Are you using "backup power" on your module? That keeps the almanac and the ephemeris in storage and should cut down time-to-first-fix.

It's not clear from the datasheet, but I'd try two different things (only one at a time):

Feed the main power directly from the battery (that goes to a max of 4.2V or so). Use the powerdown control line to "+3.3V" on your UART jack to enable/disable.

Keep it powered on the 3.3V but feed the "backup power" from battery through a 1N914/1N4148 diode (to drop the max 4.2V down to 3.5 or so).

Yeah, a ground plane could help but the Glow2 case is already metal and gounded.
[Nook Touch General] liptonthe:
As you said, it's not clear from the datasheet so effectively i haven't try to play with the backup power.

Before on the NST i setuped a low/high switch circuit to allow to go in power saving mode. I should redo one for the glow, but this time i would use a more complex circuit with a reed switch and a little magnet to keed the glow waterproof.

I definitely should try something with the backup power, but i'm worried about the discharge of the lithium battery if the backup or main line keep drain power in a permanant way i will risk at best to kill the battery and at bad a fire.

True ! But i mean, the base of the GP module could be soldered to that large grounded piece of metal that the case are. Maybe it will help.

The NST power line :
[Nook Touch General] Renate:
Well, the current through R1 is probably a lot more than the backup power. You could use a separate battery like a CR2032 if you wanted.

Don't you use data to the GPS module? You might want to configure some things some time.
[Nook Touch General] Renate:
I'll just add that disassembly can use exported symbols or kallsyms that give you the entry point of functions. The stock disassemblers (like objdump) only look at one line at a time and so they can't see the bigger picture. There are very clever disassemblers (like IDA) but they cost money. There are things that strike a happy medium that can identify common things. Here's a chunk of a kernel. We know the function from decyphering kallsyms. Without correlating the load instruction at 8083828 with the add instruction at 8083830 we'd never find the correct string. Notice that the two instructions are not even contiguous!

; Func(4) try_to_run_init_process
8083800:	a9bd7bfd	stp	x29, x30, [sp,#-48]!
...
8083828:	d000a120	adrp	x0, 0x94a9000 ; "<3>Starting init: %s exists but couldn't execute it (error %d)\n"
808382c:	2a1303e2	mov	w2, w19
8083830:	91284000	add	x0, x0, #0xa10
8083834:	9403d9ca	bl	0x8179f5c ; printk

This is 64 bit, but 32 bit ARM often uses constants, so that means correlating two instructions and one constant to notice that we're referring to a string.
[Nook Touch General] liptonthe:
Hum that's an idea, so you think the CR would be enough for the backup.

Yeah about the data, i wasn't projecting to let it connected but you right it could help later !

Thank's for the tips about the u-boot edit ! I'm gonna work on that. Unfortunately i live the city where i am tomorrow then will not be able to works on projects before the middle of the next week.
[Nook Touch General] Renate:
Actually, I'm more for just connecting it to the LiPo using a diode to drop the voltage down a bit.

I don't have the same module you have so I can't take any measurements.

I can't even seem to find the real datasheet for the actual u-blox module.

Are you setting the baud rate on the module every time you boot up?

Using backup power will make this unnecessary.

You could also configure/check out the module using the desktop "u-center" software.

You'd need to make sure that the backup power is connected when you switch from Arduino to Android.

There is also some Android software.

I use a u-blox NEO-M9N for navigation. Right this second it's using 25 satellites on all 4 GNSS systems.

I also have an older USB Sirf IV "puck" that I use the 1 PPS output for frequency calibration.
[Nook Touch General] liptonthe:
The GP-735 datasheet say it's designed to work on a range of 3.1 to 5.5 V on main line, so does the diode is relly necessary in this case ?

If i'm directly connected to the Li-Po, the backup power is unecessary because it's alway powered on right ?

Maybe you would mean connecting the backup power line throught a diode to the Li-Po ?

The GPS driver installed on top of android setup the baudrate at the system startup. But the module itselft will already work at 9600 baud by default.

I will definitly take a look to the u-center software to tune the module itself ! It would be very cool to clone some functionnality used in expedition GPS like be able to switch between short and long interval localisation to economise the battery. That's another very good reason to connect the RX data line to the Glow to be able to pilot it when necessary.

didn't understand, but it must be related to the u-blox software, i'll gonna take look. --> EDIT : After some research i readed that the module doesn't have a non-volatile memory so the only way to keep configs is to keep it ram.

The u-blox NEO-M9N you use seem have very nice performance but also quite small size ! that's interesting.
[Nook Touch General] Renate:
The backup line has a lower voltage tolerance than the main power input. It needs the diode.
[Nook Touch General] liptonthe:
So it was for the backup ! i'm in phase with you so :) I will be able to look to apply thoses modifications next week !
[Nook Touch General] liptonthe:
Today i surprised my glow updating by itself on my desk near my computer.

I just have the time to grab my phone to take a picture of what happenned.

It's looked like it was a kind of automatic OTA but performed over the TWRP recovery.. (Rebooted into recovery then instant flash).

Of course it's now stuck in a boot loop loading until the end of the universe.

After sevaral try i'm not able to boot back in recovery mode to try a wipe cache or bring back a backup. The ADB interface is now recognized as "unauthorized" .. not cool !
[Nook Touch General] Renate:
Hmm. Did it say that it completed the update successfully?

Are you getting the unauthorized while in the system or recovery? That is usually because you have ro.adb.secure and the /data partition is inaccessible and you can't read /data/misc/adb/adb_keys Normally recovery shouldn't be ro.adb.secure

Worst case you ground the test point and imxlink.exe the regular u-boot with the UART connected as console and tell it to fastboot. If you're still floundering I'll see if I can make a u-boot that goes automatically to fastboot without needing a console.
[Nook Touch General] liptonthe:
Yes the update completed with success ! After the reboot it was loading. so i waited to obtain something, but after wait the entire afternoon i faced the reality, it's not going to show me something more.

I guess it's normal to get an unauthorized ADB, the only state of the glow for the moment is this stuck update boot phase. Also i'm very surprised that i'm unable to go in recovery mode.

I think yes, i'll going to use the imx solution. to reflash my old u-boot, then the arduino to try pass in fastboot mode. I'm on the road now, so i will wait until tesday to perform the trick.
[Nook Touch General] Renate:
You can always try my NeoNoogie as recovery. It won't automatically do any update unless you specifically execute it. Of course it has ADB.
[Nook Touch General] liptonthe:
Yes ! It will be a good occasion to work with :) Yeah the OTA is pain .. i will need to block it in the future.
[Nook Touch General] Renate:
Here you go, ub2fb. It automatically goes to fastboot.
[Nook Touch General] liptonthe:
Hi @Renate, i'm back :)

Thank's you for the Fasbooted U-boot image, I've just tried it, but it look like i'm not able to gain anything more for the moment,

This is the result i get from the imx cmd line, it. It wain for ADB/Fastboot forever.

The GPS module is actually disconnected.

Please download a new imxlink.exe

It should say:

C:\>imxlink.exe /?
... 2019-2022

That's just a cosmetic change (and a check that you have something that isn't ancient).

Run Zadig and look for the fastboot interface at 18d1/0d02

Use usbview.exe and see if something is showing.

If you screwed up your ntxconfig that could also be a problem.

Basically, we have no idea what the update did.
[Nook Touch General] liptonthe:
Yes i got the last version of imxlink from your website from the beggining. all is okay about that. So, i've replaced my driver with Zadig, but i never used this soft before. IDK if i was doing good.

I used UsbDeviceThree instead of usbview, but it seem to be the same.

The report attached is related to the glow. She is viewed as "SE Blank Megrez" on windows.

It's quite strange because all my toolbox and computer has not changed, the imxlink solution was working well the last time. But here it's look like different, no recovery mode etc..

I never heard about ntxconfig and google is not helping with this keyword. but yes, the update seem blasted away several things.

Edit: When i try a regular boot for the glow, it's obviously still stuck in a loading loop, but i'm able to see the storage and browse in. And adb stay unauthorize.

I'll gonna try to reconnect my Arduino to the serial to try see what happen.
[Nook Touch General] Renate:
Yeah, "SE Blank MEGREZ" is the iMX6 ROM bootloader. Maybe they had an employee named Meg?

The question was if anything appeared after the bootloader.

ntxconfig is the binary configuration that NTX used instead of device trees, it's proprietary. See: http://www.temblast.com/ntxhwcfg.htm

The bootloader does not need a driver because it's USB HID.

Fastboot and ADB both need the stock Android WinUsb drivers, that are in fact normal WinUsb drivers but they use a different GUID.

If you use Zadig drivers for those you will have to patch fastboot.exe and adb.exe

I still have no idea what the state of things by you is. Did imxlink.exe run through correctly?
[Nook Touch General] liptonthe:
Probably ! It's look like i'm not able to get sometheing after the bootloader.

Ok, i guess something still work, it's just that i'm locked outside of the box. Because the Nook logo appear, the loading is loading then the USB MTP goes up on windows, i can browse.

Even if it's stuck for the moment it's like if the glow was dead.

After somes tests i've come back to the regular driver.

I've retried the imlink method but now i get a write error.

Hi @Renate, i'm now considering buy a new BNRV510 from ebay us, thoses models are quite hard to find here in France.

I'll gonna keep you intune when i will receive it :)
[Nook Touch General] Renate:
A couple of years ago I bought a pair of them for $20 each.

The goofy thing is, many modern processor chips have GPS processing built in. It's just that the ereaders don't have antennas. Such is the case with the SDM636 in the Poke3.
[Nook Touch General] liptonthe:
Yeah ! I founded one with a dead screen, that could be a cheap solution for me.

The most of the time the shipping is the expensive part of the Glow !

I guess other devices could be tweaked with the GPS function, but from my research the Glow2 allow a small form factor, waterproof, decent calcul capability (for an eReader).

I believe it's possible to achieve a device that challenge professional expedition device on some points.

Maybe one day, if my skills become better i'm gonna design a complete device around E-ink screen technology from scratch using NXP dev plateform or something like that..
[Nook Touch General] Renate:
I'm still unclear what the state of your original Glow2 is. Can you run NeoNoogie on it? Can you do a manual update?
[Nook Touch General] liptonthe:
I spend much more time AFK than i would like these times.. sorry for the late answer.

Actually i’m not able to go in recovery, fastboot or bootloader mode. Then the system doesn’t load completely and stick to loading state so it’s unusable.

For the moment it’s stucked but i’ve not spend the time to try reconect my arduino to read the logs.

they don't mention any particular device or exact date, but the only device in my account with calling plus feature is the LG V40.

apparently sprint has a mess with the launch of voLTE and that's why the update has taken so long. I imagine that the same with the LG v40 US unlocked model does not receive update since it updated to android 9 pie about 5 months ago?

Hi Ladies and Gents-I am having the WORST time finding a solution to my battery life problem. I've even goten a replacement device from AT&T in case it was an internal problem.

Sitting idle during the day except for the device checking email every hour, a text here and there, and an occasional 5 minute phone call; my Tilt ends up at 20% at the end of an eight-hour work day.

Others have indicated that they've had upwards of 70% battery at the end of the day, with much more device use!

I've had the battery tested at Batteries Plus, and they conclude there are no bad cells nor leakage.

I live in the Indianapolis area and am using Radio 1.64.08.21 and Utty's April 29th Hybrid ROM if that's useful information.

I also use GPS golf software, but can only last 8 or 9 holes. It's madening!

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] scotchua:
Well, if you leave the program running in the background instead of closing it, then it will continue to actively use the GPS. In which case 8 hours would be a good battery life. Try actually exiting the programs that use GPS when you are not using them to see if that affects the battery life. Some roms will kill the program if you click the X in the corner, and others only minimize it. Just a thought.
