So I had some weird issues while using navigation today.

I'm running stock, rooted BTW.

My navigation locks on in seconds, maps, whatever, as soon as I type in an address in nav, I'm taken right to the navigation screen. That part is good.

however, every 10 seconds or so, it seems like the navigation would lag, then catch up to my position.. as it doesn't stay locked on.

Would the AGPS patch in the dev forums fix this? I did not see this addressed anywhere in the notes.

I would try clearing data and cache for Maps in Application Manager. (maps is nav) and if that does not work, uninstall MAPS and reinstall from Google Play.

You mean your ROM? Did you make a backup? You always make a backup before flashing a new ROM.
[Sony Xperia P, U, Sola, Go] mikereidis:
It appears that at least one person's Sola is capable of transmitting an FM signal over short distances. I imagine many others can transmit as well as P, U & Go but I'm not sure yet.

If this works widely, these will be among the very few Android phones that can transmit FM, and the only widely available 2012 device I'm aware of. The only other is the T-Mobile/HTC Mytouch 4G and it's also unofficial.

I'll get an app posted soon that can be used to test. I don't have any of these phones, but a Sola owner is helping me a lot. I expect to get one soon, perhaps a U.

Probably most of you in the Sony world aren't aware of my Spirit FM app, since I've been unable to support most; see my sig.

I'm in the design phase for Spirit2 and it will use the ST-Ericsson proposed Android FM API slowly making it's way into AOSP over the last few years. Spirit2 info also in signature at bottom.

Happily for some Sony 2012 device owners, and more-so for cg2900 based device users, this is the API Sony uses in Radio3.apk. CG2900 devices may be the only ones with FM transmit at present though.

I understand the General section isn't for questions, but if mods are OK with it, I'd be interested in "discussing opinions" (which happens in General all the time) about which phone might be best for my development work on this FM API.

Feel free to ask any questions related to FM. I presume people can do that in an info thread. And yes, I've ensured there are no question marks in this post, LOL.

So these are the devices I'm considering, preceded with their best shipped prices in Canadian $ on Ebay:

$ 210 U ST25i

$ 230 Sola MT27i

$ 240 Go ST27i

$ 300 P LT22i

My take reading a bit here is that P is the "best", and as old as U, but U has more custom ROM development.

I'm presuming the carrier unlocked devices, mostly from Hong Kong or China, are also boot-loader unlocked. I think I should avoid local devices, such as from Rogers here in Canada, because they have locked boot-loaders.

I just need a good phone for testing both stock and custom ROMs not normal use. I should probably wait until transmit capability is tested on a few phones successfully.

[Sony Xperia P, U, Sola, Go] XperianPro:
How to make it work?
[Sony Xperia P, U, Sola, Go] mikereidis:
How to make what work ? :)

The Nov 26 test release linked in post 1 of my thread should actually work on stock or stock derived devices, but I think it won't run a second time without rebooting.

I'll try to put out a test release in the next day or 2 that will work better. I have it running now w/ RDS on CM10 on my OneX LTE, using the libfmradio.sony-iris.so library found on the Xperia T and similar. And hopefully my Sola tester will report good results tomorrow.

There are still some potentially difficult issues on AOSP type ROMs such as FreeXperia etc., mostly audio related. Audio issues are my most difficult task but stock ROMs make it easy. At least this FM chip is V4L and easy to enable on custom kernels, unlike Broadcom & TI combo chips that can be a pain with bluetooth issues.

BTW, these devices can support FM recording, on stock ROMs at least. I guess most Sony's can.

I looked a bit at the Snowball dev kits for cg2900 etc. None of them support FM, just like the TI Panda & virtually all dev boards. I have to imagine the regulatory issues are a pain.

...

I almost hate to say it, but I wouldn't be here in the Sony forums if the Android API used by Spirit2 wasn't hosted natively on these devices. Cg2900 devices especially seem to be the reference platform for this ST-Ericsson originated API.

I've intended to focus Spirit2 only on the most popular devices with custom ROMs; mostly Samsungs and HTCs. It's WAY too much work to support devices I don't own for testing, and to try to support more than a few dozen devices, of the thousand(s) out there.

And yet stock Sony's support this API, so it's difficult to say I won'

t officially support them. Anyway, consider this a warning that I might decide not to officially supported stock unrooted Sony's at least. My niche is FM on custom ROMs; and average "normal" smartphone users aren't really my target.
[Sony Xperia P, U, Sola, Go] Kess78:
Hi,

Here is a little FM transmit test app. Audio is not working yet but you can get a signal and see RDS data on another radio :)

How it works :

Turn on a radio on 87.5 Mhz

Make sure a headset is connected to your device as it works like an antenna

Open the app and wait 5 seconds.

Click on the Freq 87500 button

Click on the RDS button

Now if you place your device next to your radio you should get a signal and see "Test RDS written". The signal strengh is not very good so it can be hard to have RDS.

To stop transmit just open the stock FM radio app.

Feedback is appreciated on every STE devices :)
[Sony Xperia P, U, Sola, Go] freshbooy:
it first run was good

but next run get FC

try to uninstall and then install but no luck!
[Sony Xperia P, U, Sola, Go] Kess78:
Thanks for feedback

You have to open and close the stock FM app after you use the app to reset everything.

Also make sure you wait 5 seconds after opening the app before pressing the freq button.
[Sony Xperia P, U, Sola, Go] mikereidis:
Thanks kess ! :)

BTW, I think that not every FM radio (especially non-smartphone radios) can go down to 87.5. US radios in particular may only go down to 87.9 or 88.1.

For anyone reporting, please report your device, where you got the device, and ROM. Looking at freshbooy's posts I guess he also has a Sola but I don't want to search through everyone's posts or guess.

And for now at least, we're just trying to see if transmit works. It's not particularly usable with no audio, and we can't be sure if audio can even work. I think audio will work, when figured out, but we'll have to see.

So that's two reports from Sola that are positive; Can we get reports for U, P & Go ?

I'm asking "where you got the device" because of my concerns that transmit might be somehow disabled on variants from specific regions or carriers, so please specify the country &/or carrier you purchased from.

I think that only stock or stock derived ROMs have a chance of working with this current FM transmit app.

I can't stress enough how weak the signal may be, and to see RDS data requires a VERY clean signal. For testing it's probably best to loosely wrap the full length of the Xperia wired headset cable around the full length of the antenna of the FM receiver. We may be able to increase power; we tried but first attempt didn't succeed.
[Sony Xperia P, U, Sola, Go] mikereidis:
I would appreciate getting more feedback on FM transmit, particularly from Xperia U, P or anything ending in 'a' for North American 3g frequencies.

I have experimental transmit in Spirit, but haven't posted it anywhere yet.

I'm about to buy a U, and I guess it will be ST25a so I can use the 3G here with Bell Canada.

AFAICT, the 'a' models still have FM (receive at least, I think.)

I guess if the vendor allows returns, I can consider that if transmit doesn't work.

Dec. 4 test release of Spirit FM Free: http://d-h.st/HDa

Not tested on anything but HTC OneX LTE and Sony Xperia Sola MT27i.

Unofficial support for some stock Sony 2012 devices. Transmit on CG2900 devices: U ST25i, Sola MT27i, Go ST27i, P LT22i.

FreeXperia and other AOSP ROMs not supported, but S4/S4+ devices may work rooted with OneX LTE etc support.

CG2900 (libfmradio.cg2900.so): U ST25i, Sola MT27i, Go ST27i, P LT22i

Broadcom proprietary (libfmradio.brcm-prop_rx.so): S LT26i, Acro S, Ion (Not sure about Xperia Miro, Tipo, J)

Qualcomm WCN3660 (libfmradio.sony-iris.so): T LT30p, TX LT29i, V LT25i

FM Transmit test mode: Ensure wired headset is plugged in and wrapped in a "long way" along the length of a test receiver antenna. Set Debug-> FM Chip to "STE AFM TX" and restart Spirit. Can frequency be changed without restart ? There will likely be no audio.

Use seek down and seek up set different RDS data patterns.

FM Receive mode: either use automatic settings, or set Debug-> FM Chip to "STE AFM RX", set Audio-> Method to "Sony/STE/Android" and restart Spirit.

Plug a headset in each phone and place them very close to each other.

Tune the reception phone to 87.5. Put it on speaker mode so it will be easier to hear the if it transmit.

On your xperia u open the app and wait 5 seconds.

Click on freq 87500. Now on the other phone you should not here noise anymore. You should just hear nothing like if a radio was broadcasting without any sound.

Then click on set Rds. Now if you place your phone very close of each other you should see "test Rds" written on it.

This work perfectly on my sola.

[Sony Xperia P, U, Sola, Go] mikereidis:
So you think you saw transmit working ? I think I've changed my mind about ST25a and will get a ST25i, so I'd hope to see yours transmitting.

With the Dec 5 Spirit FM app, set to use Debug-> FM Chip = "STE AFM TX", you can change the RDS data by hitting the seek up or seek down buttons. They are the top buttons, under the graphic volume slider, on each side of the big frequency button. They show Previous and Next audio type icons.

We may be able to change transmit power, but I'll need to get one of these phones myself first.

Not sure what is this all about!

My experience:

I installed this Spirit Free and plugged the hands free! (Sony Xperia Sola bought from middle east (SI 1261-5054)

some noisy sound was played! Set Debug-> FM Chip to "STE AFM TX" and restart Spirit,

sound turned off!

I bring another phone (Nokia X6) attach another headset on it, bring both headset very close and set both frequencies to 87.5 ... noisy noisy sound played, set Spirit frequencies a 0.1 MHz upper or lower ... noisy sound make louder, set Spirit frequencies to 87.5 again noisy sound get deeper and quiet.

Set Debug-> FM Chip to "STE AFM RX" and Set Audio-> Method to "Sony/STE/Android" restart Spirit, sounds still not working and it doesn't matter if i put 0.1 MHz lower or higher the X6 radio still playing noisy noisy sound the same!

Hope it helps

Thanks
[Sony Xperia P, U, Sola, Go] mikereidis:
It's about getting FM working, both for receive (like the stock app) and the very rare bonus of transmit capability.

Thanks for your feedback. :)

OK. I'm just learning Sony terminology. Sony "hands-free" means a wired stereo headset/earphone with 1 or more media buttons for pause/play etc. Right ?

SI number concept is new to me. Good, something more for me to learn.

What you describe indicates FM transmit works for you. We don't have audio yet, but there are test tone capabilities and I'll get audio in there eventually.

So that's confirmation for transmit on 3 Sola's, but nothing else yet. I guess the U couldn't be confirmed ?

If TX works for you, and you're running a stock or close to stock ROM, then Rx/Receive should also work. Maybe a full cold phone reboot would help.

Is the stock FM app working OK ? It may even be possible to have both Spirit and stock FM app running at same time, with little or no interference.
[Sony Xperia P, U, Sola, Go] mikereidis:
So you didn't get transmit working on your U ? Did receive work OK ?

Is there something I can add to the test instructions to make it clearer or easier; I'm not sure exactly what you tried.

Thanks...
[Sony Xperia P, U, Sola, Go] sijav:
Second experience: :D

well RX still didn't worked until I open the Stock FM radio and now the RX spirit is working!

The next test: I open spirit and it playing radio OK and then I open the stock radio ... suddenly spirit's sound turned off (it was still on RAM) and Stock FM didn't turned on no matter what,

I restarted my phone and reopen the stock FM Radio ... Working OK, while Stock FM Radio was playing i open spirit (takes so long to start) but it looks like working by changing spirit freq the stock freq changed as well by changing Stock FM Radio spirit freq changed so!

I then click on turn off on spirit and both spirit and radio turned off and didn't turned on after that until I reboot my phone!

.

As for the SI number it's a code determine where did you get your phone and what's your operator (mine's get from Sony manufacture!), It's mostly used by our phone's update application so that the server know which ROM should be installed on your phone.

thanks and hope you find a way to transmit music by Walkman through FM Radio :D

It's good to know we have such a great ability :)
[Sony Xperia P, U, Sola, Go] mikereidis:
I think there is firmware that needs to be loaded. We had this before but I thought it was fixed. Maybe needs SU. Maybe turning Bluetooth on would help.

Spirit would keep running if Debug-> Audio Focus is set to "Disable" and Spirit is restarted. Otherwise the stock app takes "permanent audio focus" and Spirit turns off, as if the FM app was a regular audio player. But this may cause problems with audio notifications.

OK. I'll fix what I can when I get one.

Great ! Has anyone ever seen a hardware difference due to SI, other than 'a' & 'i' variants ?
[Sony Xperia P, U, Sola, Go] sijav:
well I have super user ... Turning on Bluetooth doesn't help much.

I think it disable the main FM Radio thing (the hardware)!

and audio focus was set at automatic.

Thnx a lot :)

Not sure ... mines from middle east is as same as the one from hong kong! both have 3Gs, just differences was about it's charger and it's accessories.
[Sony Xperia P, U, Sola, Go] mikereidis:
I decided to buy an Xperia P LT22i.

Apparently it's Quad band 3g so I can get International and easier ROM-ing along with local 3g. :)

And ROM dev & tech interest are still pretty good, and more RAM and space...

Hopefully I'll have it early next week from Hong Kong. From EBay vendor imobilephonex I was happy with for a OneX buy. $15 more than the cheapest, but seems not to have the "must be sealed" fine print others have on returns. And 99.7% versus 98.4% can be a big difference as I saw on another buy.

Is this gonna working or what?
[Sony Xperia P, U, Sola, Go] mikereidis:
Perhaps not for transmit. :(

I got my Xperia P LT22i from Hong Kong today, and I can't seem to get a signal out of it.

I tried my apps, the other test app, and spent the last 4 hours writing code at the V4L level. Nothing. At least I found out the default power level is at maximum, so I'd guess no more power is possible.

Everything LOOKS like it works, but that won't help if the transmit pin is grounded. There's always some possibility it's related to the specific firmware files.

So, so far, the only transmit confirmations we have are for the Sola, and I'm not sure every Sola sold in every region could work.
[Sony Xperia P, U, Sola, Go] sijav:
At least for china and middle east works ... and it seems that the hardware and software of all Sola is the same even the Italian one which is Sole instead of Sola is the same!
[Sony Xperia P, U, Sola, Go] korenisko:
Hi Mike, I had tested newer spiritfm to tx and it probably worked. On sony micro system I tuned 87.5 (there is no fm radio ). On phone opened spiritfm and headset cable I give close to microsystem antenna and on it, there wasnt rds text, but stated tuned as I found some working fm transmit. So, I tuned another freq on spirit and on micro and I heared, that signal was corrupted by spiritfm... So, on xperia p transmit worked. I have european phone with latest ics fw .54.
[Sony Xperia P, U, Sola, Go] mikereidis:

[Sony Xperia P, U, Sola, Go] mikereidis:
Thanks, sounds like a better/quicker idea than to disassemble etc. :)

EDIT: OK, I flashed that EU firmware. I originally had Hong Kong SI: 1261-5847. (I guess, I got it via getprop.)

No change.

But I've retried with my most sensitive phone, which is the only one to pick up RDS well without an antenna. With the headset cables wrapped together I've noticed that there is definitely an effect on the receiver, when the frequency is tuned. But it's not a clear silence with particularly notable RSSI change and RDS hasn't had a chance. Maybe it would improve if I tied the headset cable grounds together.

I'm not sure if this is just some RF leakage, or if there's something I can do to improve the signal. I'll see if I can adjust power and transmit some test tones.

I also finally installed my SIM, thinking that might be an issue. So the phone knows I'm in Canada, and who knows if it might disable transmit in certain countries.

Also tried a different wired headset, but I see Sony doesn't seem to like that.

BTW, the transmit power is configurable, it appears, from 88 - 123 dbuV. That would be about 12 microwatts to 40 milliwatts, assuming a 50 ohm antenna.

The default power appears to be the maximum, which at 40 mW should be good for at least a few feet^H^H^H^H decimeters.
[Sony Xperia P, U, Sola, Go] korenisko:
decimeters :eek: :)

I used any Philips ears, not from xperia p packing. RDS was not displaied too, but "TUNED" appeared.

and little OT:

In Google Play, there is SpiritFM 1, which isnt compatibile with xperia p... SpiritFM 2 isnt there... When you add it to Gplay? In January as you stated soner?

Only available spiritFM 2 are betas, so?

EDIT:

Xperia P have good fm reception without headset. So, I like fm radio listening without headset :)
[Sony Xperia P, U, Sola, Go] mikereidis:
Spirit2 mostly exists as some code within Spirit1 for now. The code that makes it work on Xperia devices supporting Radio3.apk.

Actually, the other day I finally created the first Spirit2 app, as a "shell", and it does absolutely nothing so far.

January is about right.

I haven't tried much without antenna, but yeah, my P works fine with RDS, and RSSI at the maximum of 62 (!) on strong stations at 106.1 and 106.9. A somewhat weaker station at 88.5 though only shows RSSI = 2 and no RDS. Higher frequencies need shorter antennas and may be better with no wired headset antenna.
