content: Seeking testers for the iphone application sign up here:https://goo.gl/forms/rkZiS3Jh3HJpmblC3Please use your apple app store email address as I suspect it will make things easier.Please take screen shots, even if there isn't a problem we don't have enough screen sizes in the office to submit to the App store.We need screen shots specifically from an iPad and 5.5" iphones, we currently don't have any of these devices.

content: @Seppy,backer 1443Well, I have an iPad and a 4.7" iPhone, and have written a few apps including the core and plotting part of an i121GW app. Unfortunately, I don't have a meter to test with. Will the screen shots you want require a connection?I'd like to try it anyway.

content: Quote from: Seppy on June 08, 2018, 05:21:16 amI installed the app and did a very quick test logging temperature for a few minutes and then mailed the data to myself. It looks good so far. I would like to have the start Date and Time set in the file header. Maybe there is an option for that, I have not done any exploration...

content: Quote from: JonM on June 12, 2018, 02:11:20 amThere isn't currently an option for that, I'll add it in, I don't want to do a full time stamp for each item though as it makes the data less importable.I can however change the default filename to the following, how does that sound (it would also be the default email title):"Log DD-MM-YY, HH-MM-ss.csv"Edit: for sortablility the following format was selected, what do people think?"YYMMDD, HHMMss Log.csv"P.S. Post screenshots if possible we really need them for the App store submission.

content: Quote from: JonM on June 12, 2018, 02:11:20 amI’m confused. You are able to log or retrieve logged data with the App?I’ve installed it on my iPad mini. I.m getting a nice mirror of the meters display but no ability to log or retrieve logged data that I can tell. The settings and maths buttons appear essentially non-functional.

content: Will run some tests with my iPhone 6 tomorrow once I put my meter back together (again).My iPad mini is the original model, so it can't run iOS 11 unfortunately. I considered upgrading, but I just don't use it enough (or do enough iOS app dev) to justify buying a new model. I may have to eventually now that Apple is forcing all new apps to be built for iOS 11.

This is the first App I have tried that insists on iOS 11.3 as the minimum supported version.

content: Quote from: IanB on June 12, 2018, 08:30:06 pmTrue.My understanding is that all new apps submitted to the store must be built with the iOS 11 SDK. I'm haven't done any iOS app dev recently, so I haven't dug into what backwards compatibility that provides. I imagine that Apple wants to encourage people to move to new devices though.I guess it will be a matter of what Seppy can build using the Xamarin framework, and I'm sure there are some limits to what they can support.

content: Quote from: Kean on June 12, 2018, 10:47:17 pmI can say that my iPad has been running iOS 10.x for a long time, and no app downloads or updates have so far complained about the OS being unsupported. This app seems unique in saying it "requires iOS 11.3 or higher before it can be installed".My guess is that the minimum OS level is a setting in the build that can be changed, and that perhaps the app package is picking up a default value corresponding to the latest OS release?

content: Well, on my iPhone 6 running iOS 11.3.1 (soon 11.4), I have severalolderapps installed some time ago that won't run anymore.e.g. Trying to start the ONsemi app shows a popupQuote(Yes, the capitalisation of "to Be" is exactly like that - unusual for Apple).It then has a link to a learn more screen (Settings->General->About->Applications) which shows 14 apps I have on my phone that no longer work, and with no new updates in the app store.That includes other large companies like Officeworks and Kathmandu that apparently haven't updated their apps.Anyway, back to the 121GW app - it appears that Xamarin does support older versions of iOS.https://docs.microsoft.com/en-us/xamarin/ios/platform/So unless Seppy is using some specific features requiring iOS 11 then he can probably adjust a build/publish setting for backwards compatibility (iOS 9 and above would be nice).

content: I have done some more testing and am seeing issues when my phone gets about 1.3 m away from the 121GW. Moving it closer does not recover the connection. There could be some interference so I will do some tests in a clean environment later (outside in a park maybe). The phone is an iPhone 7 running iOS 11.4I was going to test on my iPad Pro but TestFlight said that I used up my single allotted test copy. Maybe there is a setting to allow each tester to try it on multiple devices?A screen capture will be sent via mail.

I don't really see the need for commas either in this data. Space separated should be sufficient, in which case the suffix would be .txt or .dat or something.It would be good to set the logging interval, and as someone else said, a "round number" for the time interval is nicer.

content: Quote from: JonM on June 13, 2018, 12:53:41 amWindows FTW!It's true though, spaces can cause grief in scripts and on the command line. I think underscore is more portable than dash, so that would give a name like YYMMDD_HHMMSS.csvQuoteActually, comma separated with a .csv extension enables apps like Excel to open the file directly as a spreadsheet without any need for import filtering. So I would strongly favor retaining the current csv format and file type.

content: I will never open the data in a spreadsheet but I can live with the commas, and maybe I even need them for the header. 98% of the time I will be using R and if there are spaces in the header without commas that will be a problem. In any case I will still have to cleanup the column names since they will become the column names in a R dataframe, and if spaces, and parens, in filenames are an issue, they are far worse in variable names!

I'm sure when you set up an iOS device you can choose country, region and culture settings to your preference.With that said, I believe the tendency in science and engineering is to standardize on "." as the decimal separator these days.

content: A few observations from tonight's testing:1. I would like a way to change the graph update rate (e.g. every second, or every 5 seconds)- the maximum speed update is sometimes too fast, for example if logging temperature2. The scroll and pinch gestures on the graph area only affect the time axis, not the vertical axis- if I pinch or drag in a vertical direction I would like it to affect the vertical graph scale3. A minor bug: put the meter in temperature mode, press Hold so the value freezes, press Reset to clear the graph- The vertical axis does not display and graph does not draw a visible line4. Suggestion: when you press Hold the displayed value is frozen and no new readings are sampled (as expected)- In this case the graph should stop scrolling since there is no new data to log5. OS compatibility: I'd like to test the app on my iPad if you can remove the iOS 11.3 required version when installing

content: Quote from: Seppy on June 12, 2018, 06:51:48 amOK, so I can't take a screenshot of the first issue - that is on the iPad mini, when I tap the save button at the bottom of the graph, it just kicks me out of that app every time and puts me back onto the home screen without saving any logged data. This is consistent and does it every single time. The app is still running in the background - I am just booted out of it.The second issue - the graph axis values with open leads on volt setting was mostly my misreading. I did not immediately get that the small m - meant millivolts and with the tiny font I did not at first see the negative sign for negative values, so without a zero on the y axis it was difficult to orient the labels to what I was seeing on the digital readout. It would help if the axis labels specified the units (eg mV for millivolt - not just m). And with the small font, the negative sign so close to the y axis line with hash marks makes it difficult to discern on the iPad mini.The x axis time values did not immediately make sense to me either but I think I've now figured them out now.On the iPad Mini the graphing still has some issues. The axis label font is very small relative to the graph which as I said make the negative sign very difficult to discern. There are also sometimes long pauses before graphing resumes after hitting the reset button. Other times it resumes right away. Lastly the y axis labels with low values (open leads) tend to sometimes, and apparently randomly, throw a microvolt value in with the millivolt values. I have not noticed any of these issues with it running on my iPhone 5s. Screen shots below.iPad mini 4 - microvolt label inserted amongst millivolt labels on y axisAlso - very small axis label fonts - looks fine here on the enlarged posted picture on a computer screen but on the iPad mini screen the fonts are tiny relative to the graph size - especially the negative - sign.iPad mini - graph reset but no plotting occurring - even after waiting some time.iPhone 5s. OK.

content: Quote from: Seppy on June 13, 2018, 07:01:47 amI can't provide any help on how to make that work from a programming perspective.It's not an engineering app, and not exactly independent x and y control, but an example of excellent implementation of x and y axis pinch and drag, pan and zoom, etc is thethinkorswim mobile app.It's a financial trading platform but it has extensive graphing (charting) features which automatically adjust the x axis values to the appropriate scale of whatever is zoomed or panned on the y axis. You don't need an account to use the app BTW.Even though you cannot adjust the y axis independently, because of the way its implemented, it feels like you can. IOW since the y axis automatically adjusts as you pan and zoom (time wise) on the data of interest, it gives the impression that you have direct control over the y axis. Not sure if that makes sense - it's something you have to experience.

content: OK, confirmed it works on iOS 10.Pinch zoom is better now, it's more intuitive. It's still difficult sometimes to move a zoomed in section of trend to the middle of the view port. I think this is because the scrolling is bounded by the limits of the zoomed out view, so if part of the trend is near the outside border then further scrolling is blocked in that direction.I think that on a bigger screen some of the text is quite small and needs a scaled font so it doesn't appear so tiny at higher resolutions. Especially applies to < Settings > < Maths > [ 0 ], but the other blue text could also be larger. (See screenshot attached.)I still wish for a way to pause and resume data acquisition, and a way to adjust the sample interval.But overall, looking good. I do like the way you can control the meter from the app.(By the way, in the attached screenshot, I am not sure what the "686.7 m" is for at the lower left corner of the chart? It is not temperature, and it does not appear to be time either.)

content: Just a pedantic usability thing, but I get confused when I see the "Save" button on a live feed of data. What am I saving? Do you actually mean "record"/"start logging"? It seems like the functionality here is very broadly similar to an audio recording application (only in the sense that new data is rolling in all the time, and the user wants to capture that data of a certain range of time). You never open an audio recording application to find a audio level indicator and just a "save" button. You record some data, and then save it; or possibly start recording to disk.Whenever you see a "save" button, you already have a pre-existing well-established block of data (a document, a recorded audio segment, a PCB file) that saving simplyinstantaneouslycopies to disk/flash. If that's not what the button does, it shouldn't be labelled "Save".

content: Quote from: Seppy on June 18, 2018, 01:24:21 amI think the way to do this is to have a partial grid division on the right hand side of the time axis. For example, suppose there are 4.32 seconds of data. You would have time axis divisions at 0 s, 1 s, 2 s, 3 s and 4 s, and then a partial division 0.32 seconds wide to complete the width. As more data arrives the 4 s grid line would scroll to the left until there are 5 s of data, at which time the 5 s grid line would appear and also start scrolling to the left. At such time as there are let's say 20 s of data, then the grid interval would change from 1 s to 2 s, and the same process would repeat.I can show a picture of this, maybe, if you do not follow from my description.

content: Alright, I don't know who reported this error but it is resolved with another firmware update.Pre-1.22 firmware the main value was sent to the app via a 16 bit unsigned value.In frequency measurement on the multimeter it was possible to display 99.993 xHz.The 16 bits that were allocated in the packet for the 50000 count multimeter wasn't sufficient as 16 bits can represent a maximum of 65535. To resolve this the packet format was revised in a backward compatible way. I.e. future versions of the App will work with old versions of firmware (except for this error condition).We added 2 extra bits to the packet we can now display 99.999 kHz if needed. This fix will be included in Build 1.4. This fix has been tested and confirmed functional.

content: Quote from: Seppy on June 20, 2018, 01:33:24 amNono, ignore that. That's just to make the blue curve in the plot look interesting when scaled hugely. Don't look at the blue curve at all if it's confusing you; the behaviour of the tick marks on the axis (which clearly aren't a log scale) is what's actually being demonstrated here. x is time (in seconds), y is voltage. Sorry, didn't expect people to be inspecting that part of the code.I can modify the code to just have a normal linear sin wave if you want; but again that's nothing to do with the axis behaviour. It'd just look a bit silly because the plot would just be a solid blue block for most of the demonstration.

content: Never mind, looks like it was fixed in 1.5. The bug I was talking about was loosing Bluetooth connection, and when the device gets back in range and the app try’s to re-connect again it would crash. It was relatable, but I just tested again with 1.5 and it seems to work fine now.I was even able to switch between 4 devices just by walking some out of range. 20 times in and out of the garageI’m getting dizzy.I checked accrosed the iPod touch, IPad Pro, iPhone 6S, IPad mini 2 and iPhone X, looking good.iPhone X looks a lot better now also :-)I don’t allow apps to run in the background, so I found it odd even if the app was closed (minimized/background) it kept the connection. This might not be anything you can change in the app since it’s the Bluetooth that’s keeping the connection. So it might be more of an iOS vs Bluetooth conflict and background app refresh won’t matter in this case. But it was funny to walk one device out of range and watch the other device pick it up. I’m sure that would cause blanks in the logging, and both logs would need to be combined from both devices to see the full story. But I just did this to see how it would handle that situation.Another random idea for you, you can ignore it or put it on the list of future ideas. I know I’ve thrown a lot at you already. They are just suggestions.Is it possable to put a little dot in the corner or a Bluetooth icon that changes green for connected, and red for connection lost? Sort of like my mobile gimbals have, a Bluetooth connection status icon. The gimbals change the icon but I find that not to be as visible and usually miss it when it changes. That why I suggested changing the color of the icon between green for good, and red for bad lost connection.It’s looking good, I’ll do more complete testing after a night of rest.Thanks for the hard work on this,Scott

content: Quote from: IanJ on June 30, 2018, 08:53:49 pmThis app needs iOS 10 or higher to run.Apple is moving away from all older devices ad their older 32 bit architecture. The original iPad mini was official discontinued on June 19, 2015. I think this is because it runs the A5 32 bit processor.The iPad mini 2 is still cheap and runs the A7 64 bit processor and I can confirm it works in this model.The app description under supported devices also say it needs iOS 10 to run, and part of this is for Bluetooth LE but mostly for 64 bit app support. I don’t think Apple is allowing any new 32 bit apps, and all app updates must be 64 bit now to be added to the App Store for a while now. I think this was announced over a year ago giving developers plenty of time to update the apps.Apple has been good for supporting old apps and upgrading iOS on older devices for many years, but eventually technology goes to a way that things have to change with new and better hardware to keep up with performance.I can say I am surprised the 121GW app works just as good on the iPad mini 2 as it does on an iPhone X and iPad Pro 2nd gen. No difference in performance at all.Compared to testing the mooshie meter that had an app crash every 5 minutes, I have not had this app crash yet. Impressive for the first app release version by the EEVBlog team.The mooshie meter was returned since it didn’t have an LCD and I couldn’t keep the app running, this made it useless to be running with Bluetooth.

I tried 5 different 64 bit latest iOS updated devices with the same results. Same devices I beta tested with the 121GW app. Then I gave up. The videos they have in the site are not even the same app when they show how to use it and demos. Oh well. I have this one now and it will do what I need it to do.I hope as this grows and the firmware grows (or goes open source completely) the app will see features like the mooshie with the second channel for power factor. Oh wait, they limited that to 50VAC, or did they bring it back? Well if it’s limited I guess it won’t do those things for mains voltage devices like LED lights bulbs.

It is fully supported by iOS 8 with the notable exception of "Health" functionality. It is supported by iOS 9, but lacks support for major interface features as well as "Transit" functionality. It is not supported by iOS 10 or subsequent versions of the iOS at all.But unlike newer Apple devices, some older devices had a hardware vulnerability for jail breaking and doesn’t depend on a signed certificate from apples server. If his modlemhad this hardware vulnerability, I can’t say for sure. I’ve been out of it to long to remember.

content: Quote from: Brumby on July 01, 2018, 07:22:07 amSorry Ian. Sometimes that sucks. I have an iPhone 4 also. It is the one I didn’t do test in out of all the test devices. In fact I traded in a lot of the older stuff last year to be recycled because of the iOS cutoff. I figured I don’t need them for testing anymore but somehow missed the 4 in the box. I guess I can make it a test for a hot air station?With the iPod touches it’s a little different, these do not get updates every year. But I think 2 models use the processors high enough to run iOS 10. I know the 6th gen does, I was able to use it for the original FLIR ONE. And I think maybe the 5th gen might be ok, but I’m not 100% sure on that.I’m still waiting for them to drop the first watch, it’s 4 watches back but they are still updating it despite it being a single core processor/less ram and much slower then the series 1, 2, And 3. The original didn’t have a “series” name to it at all. It was just called the Apple Watch. I wish I could keep it as a collector thing but I know I won’t turn it on and charge it up every few months so the battery will just die. In something that small I’m sure the OLED screen or sapphire will crack when the lithium rechargeable battery swells.Rechargeable can be good except for storage over years if its not being used. I just had the same realization about my old insulin pump when I put the new one on last year. It won’t last 4 years in a closet for a backup because of the rechargeable battery. It’s sort of dumb, it was replaced under warranty last year from a bad software update that bricked my original one. I’m required to get a new one every 4 years so this still has technically 3 years of life left. They charge the insurance $8K (usd) but because it’s a prescribed item I’m not legally allowed to give it to someone else that needs it. I guess part of that cost covered overnight shipping replacements as a medically needed device. And they don’t have a recycling credit program yet.I know some needs it that can’t afford it, but then I would be breaking a federal law,go figure. I wish the FDA would make exceptions for these things like maybe have the pump tested and certified so it can be passed on.Well it might make a good medical device tear down video?

content: I can't get the Windows app working that's available here:https://www.microsoft.com/en-au/store/p/eevblog-121gw/9n2681hjrtm8The 121gw BT pairing seems to be working and "121GW BluetoothLE#......" is displayed in the app - clicking this shows "Connecting..." for a few seconds - but then nothing - just a blank screen.I'm using windows 10 v1803 and a HP Zbook g2 laptop.

content: On the Windows 10 app, I recorded a lot of data and then saved to a csv file, which was created OK. However, when I later went back to look at the log file I found it to have zero size and was empty. On a second attempt following the same steps with the same amount of data (about 10 minutes worth), the file was created successfully. So I don't know how to reproduce the problem.(BTW, maybe this thread could be pinned like the other 121GW threads? I had to scroll down quite a bit to find it.)

content: Quote from: IanB on August 27, 2018, 07:38:34 amOK, I just reproduced it a second time. I was running the app on Windows 10 and recorded several minutes of data (10 minutes or so). Then I tried to save it to a csv file. On the first attempt it produced a file with zero bytes. However, a second attempt succeeded.

content: The Bluetooth interface on Windows 10 seems very touchy. I got the meter to pair, but it wouldn't connect for more than a second or two before going back to paired. When the app was launched then most of the time the meter did not show up. When it did show up a connect attempt produced a "Connecting..." message from the app that lasted forever.In the end I got it to work by rebooting the computer.This might be a Windows 10 problem. Maybe it is outside your control. Many Bluetooth devices fail to work properly under Windows 10 as a quick Google search will verify.(I have not seen any connection issues with iOS.)

content: Yeah very touchy indeed, my Zbook G2 is supposed to be BT 4.0 + LE compliant but as it seems not compliant enough. Disabling the BT in bios and using a cheap BT 4.0 dongle instead the Win 10 App works. Haven't tested it much more though, mainly wanted to check that wasn't a problem with the meter.

content: It is at least somewhat windows related, some drivers behave very differently.You shouldn't actually need to pair at all. Might take a while to appear though...If you didn't pair before try do that (even though it shouldn't be necessary, some drivers treat this slightly differently).There is a new version of the windows up released, major changes.There was a dependency that I was waiting for that wouldn't allow an update to be released until it itself was updated.

If it is lack of hardware maybe someone in Australia could send an old iDevice to the mailbag (actually maybe not put 'mailbag' on it so that it does not sit on the shelf for too long...).Another possibility is to use the TestFlight app and have us users do the testing.Thanks!

content: Hi Seppy,With W10 theme set to 'Light' buttons are visible (attached screenshot). This shouldn't be hard to fix given the software project files. If needed, I can have a go with fixing this issue.Also, from usage perspective, I had trouble to switch between DMM screen/plot/combined display form - now I understand that it is controlled by click and window proportion. Is there any brif help/FAQ for the app available?Best regards,

content: Its entirely possible I have missed something, but the Win10 app isn't updating if the app isn't in the foreground, even when the app is on a second monitor, if it is not selected it just maintains the last value read when it was the foreground app, then when coming from background to foreground, quickly updates again.I was unable to find anything so enable background updating, the settings page has nothing but the connection information.Have I missed something or is this a know issue/non-issue?Thank you

content: I purchased a 121GW brand new from theofficial storein Jan. 2023, and I then downloaded theMeteor appfor my iPhone. It works well enough via Bluetooth communication, but I wanted to compare with the official121GW iOS app here. Sadly, it says Not Available regardless of whether I am signed in with my Apple ID for the USA or my other Apple ID for Japan. Is it region locked to Australia (which would be crazy)? Or is the official app totally dead on iOS for some reason?The reason I even ask is because I dislike the Meteor app because it lacks a FREEZE/HOLD feature. When logging data with the app via Bluetooth, I want to be able to tap the iPhone screen or a button in the app to freeze the waveform display so I can better examine it. If I stop logging, the frustrating Meteor app dims out the waveform display, making it harder to see! I wanted to download the official 121GW app to see if it works better than Meteor in that regard. But again, I can't find the iOS official app anywhere now in 2023!
