Hey guys,
I was just thinking about that nasty little problem with cyanogenmod and our legends and since there was no meaningfull advencment, we could put some money on it. I think from 5 to 10€ for each doner would be enough or what do you think? Of course the developer has to give us an account to send the money to.
I would just like to use the FM radio and since it is working on desire for some time now, why not on legend.
So who is ready to do it?
would support that idea.
It is already stated waaaaaaaaaaayyyy before. The FM radio WILL NOT WORK on the Legend because of it's alien architecture. Don't ask me, I don't know ****. But if you're do want to make a donation then you can donate to Ali Ba which has been the sole reason CM is running on the Legend.
This is a good idea.

here on this link http://forum.cyanogenmod.com/topic/8260-fm-radio-support-for-legend/ ale baba himself says it is possible but that he hasn't got the time for it. So it is possible we just need someone who will do it. But first of all we need more people.
I'd consider doing development on this. I was wondering why there was no FM Radio app on CM7, LOL.
At the very least I can commit to finding all the info I can gather on this issue. I have no (satisfactory) employment at present and want to break into the Android specific field.
I have 14 years experience in embedded Linux development, including lots of low level kernel stuff. In a previous life (more decades ago than I dare admit) I did electronics engineering stuff, and I still love the low level nuts and bolts.
I'm pretty new to Android however, got my first cellphone (ever!) 17 days ago, first Android phone 15 days ago, and my Legend yesterday.
I think I can learn quick, I'm CM7 nightly, S-Off, new radio one day after getting it, LOL.
So my point is I, and this project, could use help in areas of Android specific knowledge.
Does anyone know if the normal FM radio app I've used before is proprietary Google code ?
Are there any generic FM radio apps that would work if standard drivers existed ?
My quick research on this is that only a driver might be needed. A V4L (video 4 linux) driver, which I have already had some experience with.
But there DOES seem to be a V4L driver already for Linux for the TI WL1273 chip apparently used in the Legend, and apparently a number of other phones. So in theory, this job might be as easy as integrating an already written driver in to the CM kernel, as a kernel module or 2. There MIGHT be some copyright issues with any chip firmware though.
Alas, some comments indicate using such a driver might interfere with Bluetooth functionality.
Interesting stuff about the 1273 chip is that it may support an FM transmitter, and it supposedly supports WiFi N. But who knows if needed hardware support might not be on the PCBs.

I've been reading that there IS an FM Radio app integrated into CM now. It comes from MIUI, a chinese group of some sort that also makes an Android ROM.
The app apparently uses /dev/radio* which is the standard V4L radio interface. I have these also on my Hauuppage PVR boards I used for HTPC before I went completely digital for movies, tv, etc.
So yes, what we need is integration of a driver into CM kernel, but coding may be needed to fix bluetooth driver interference etc. And of course who knows what else might be needed.
I'm reading that FM is much more important to those without data to stream. Not all of us live in wireless data dense cities and countries.
Would be interesting to see what frequency range can be received and maybe transmitted.
Would be MOST cool to stream from video camera to transmitter for local "pirate TV" type functionality, LOL. Actually can't imagine ATSC or even NTSC (or PAL etc.) encoding possible, but wireless streaming will do the job...

Thanks for joining in, great highly appreciated. If there is any time left it would be nice if you could look into the GPS problem with CM 7 it is currently not addressed.
Anyhow thanks for your participation and contribution.

@mikereidis
So are you going to try and port it?? If you will and you'll succeded then you will be the legend in Legend community!

I can keep my eyes and ears open to GPS, but best to concentrate on one issue at a time.
What is the GPS issue ? I thought it didn't work on my phone after new ROM but within a few hours it was working OK for whatever reason. And now I see 2 metre accuracy compared to the minimum of 5 on my Optimus Chic.

I'll do whatever it takes.
The userspace FM Radio app shouldn't need any porting work AFAIK. It seems to already be in CM 6.1 ROMs for the Nexus One (any others?). So I'd guess installation would just need to be enabled for other phones.
The tricky part is getting a device driver working that creates a /dev/radio interface for the MUIU FM radio app to use. There IS already a Linux driver for the WL 1273 the Legend uses, but it might need some modifications to run on the Legend.
But there is some complicating factor regarding bluetooth drivers, so it may not be too straight forward. For initial testing at least the bluetooth drivers could be disabled.
What about HTC's kernel source. As I told in cyanogenmod forum the drivers should already be in HTC's kernel source. If the code is there it should be easy to put it into CM7 kernel and use HTC's FM Radio app. Or what do you think?

Yeh, thats the problem. GPS is working on some devices and on others not and nobody knows why. As a matter of fact when I'm running CM 6.1 its working great. Flashing CM 7 no change to get it working. As mentioned others are reporting the same issue with CM 7 on some its working on others not.

When I get tired of Google maps seeming to take forever to figure out my GPS location, I've downloaded and run the "GPS Test" and "GPS Status" apps. I did so and for some time the status color on one of those showed yellow, meaning no GPS fix, but power on.
Anyway sometime later it was working. One of those apps downloaded data to make cold starts work faster and that may have helped. A few things to try for anyone interested anyway.

The problem with running the HTC FM radio app on CM is that it, like many other HTC apps, uses the HTC framework with Sense UI. So CM can't run it, although stock or modded Sense ROMs should be able to.
IMO right now the MIUI app is the way to go, and it's open source so anyone can modify/fork it.
Yeah I think a /dev/radio is likely in HTC source, but it's possible it's something different and/or kind of proprietary.
The Chip manufacturer, TI, and their partners who make RF modules based on the chips, DO have android /dev/radio drivers. So they are definitely out there somewhere.
I think, as usual that "In Theory" this should be a simple matter, in reality there is usually some problems to solve. Otherwise we'd have FM already in CM.
A few pointers:
TI 1273 has a few interfaces for communication. One of them being a (standard) serial via bluetooth, the other one I2C.
HTC did not use I2C because they already had to use the serial interface for bluetooth and it's a lot cheaper that way (that's what all manufacturers do, by the way). The wl1273 driver in the Linux kernel does have support for the FM capabilities, but unfortunately via I2C only.
So basically we already have all the drivers we need in place (tiwlan_drv, sdio), no kernel stuff needed. What's missing is valid documentation about how to enable radio, route it to the headphones, seek/tune, etc.
You could reverse engineer /system/bin/btipsd, which does bluetooth and FM communication in original HTC releases.
Once you are able to control FM stuff (with bluetooth turned on) write a nice summary and I'll ask cyanogen how to implement it. Won't be that hard, given the fact that currently all supported devices use the serial interface via bluetooth.

Thanks ali ba ! Yes I know about cheap manus, I've worked for a few, LOL. Linux VOIP and security appliances mostly though.
By "The wl1273 driver in the Linux kernel" do you mean the TI provided W1273 driver in the CM7 ROM ? I had thought that driver was for WiFi only, or perhaps WiFi + Bluethooth. Or does my seeing an rfkill device mean FM radio is in there too ? Would it create a /dev/radio device ? There are some FM init BTS files that may enable FM.
My understanding is that the WL1273 WiFi driver in the mainline Linux kernel (not the Android kernel) is WiFi only. There's a guy from Nokia trying to get WL1273 FM radio only driver into main Linux kernel but not there yet. That driver will be separate from WiFi driver even though they may both have WL1273 in the name.
I've been finding some HCI commands usable with hcitool to do audio routing stuff at least. RevEng has been a specialty of mine, so I think if it can be done, I have a good chance.
Quickest route to a working FM radio on Legend is to find an existing app for another phone that works.
Phones with the WL1271/1273/1281/1283 chips include original Moto Droid, Droid 2, Droid X, Motorai, Nokia N800 (or N900?), N8 (?), B&N Nook Color.
There's a thread here on XDA about Droid 2 phones using the Droid X FM radio app with success. I tried that app but there seems to be some problem launching the fmradioserver.
I saw a logcat message that may indicate I need to "adb install" the APKs instead of just copying them to /system/app. I tried but got the error that indicates the UID does not match the signature. I guess that's not an issue on Droid 2 (or motorola phones in general?)
Does anyone know if/how to mod/repack an APK to avoid the UID signature issue ?
A few more of my findings for anyone interested. BTW should I or someone create a thread in the dev section at this point ?
As mentioned above a guy from Nokia is trying to get a V4L2/dev/radio driver for WL1273 into mainline Linux kernel. That driver could be integrated into our kernel, but it might take a bit of work. And as mentioned that driver is not in kernel yet and may have lots of changes still coming in the next several months at least.
But TI also has a driver, and it's meant for Android. I haven't been able to grab source code for that driver yet. I think TI driver references WL1283, the biggest baddest version with GPS too. But driver is supposed to work on all 4 variants, down to WL1271.
TI has a command line app for testing fm radio, I think called fmapp if memory serves. It's possible this test app could at least help with exploration.
Unlike the poor original Droid owners, we are lucky that we know our FM receive antenna is connected, since stock Legend has FM radio. But there seems to be a different pin for FM transmit so it's possible we will never be able to transmit FM more than a few inches. But Tx would just be a bonus, but a potentially wonderful bonus.
And, ya know, I'm not even sure if MIUI FM app works with /dev/radio. I was looking at some source and it seems to be hardcoded with Broadcom chip specific stuff.
Oh, and my understanding is that even if we ever managed to get Wireless N working (with a new or improved stack perhaps?), that it will likely kill batteries quickly enough to be effectively unusable. Would be interesting though.

Hi,
Could somebody with a rooted Droid and some insight into how Linux bluetooth works try to test if we can enable the FM radio part of WIFI/BT chip (wl1271) in Droids/Milestones.
I downloaded some init scripts from Texas Instruments that should allow enabling the FM part. I don't know if there is any antenna or if the headphones can be used as antenna though. Can't try this out myself as Milestone hasn't been rooted yet and I'm not allowed to use 'hcitool' or 'hciconfig' commands without root.
I have attached the init scripts downloaded from: [h]ttps://gforge[dot]ti.com/gf/project/wilink_drivers/frs/
More information about how to use them: [h]ttp://www[dot]omappedia.com/wiki/WiLink_Connectivity_Project
Files and links are for the Zoom2 development platform which uses same hardware as our phones. Don't know if some config files should be altered also to enable FM radio.
I also found TI's own FM radio test application. Source is here: [http]://git.omapzoom.org/?p=platform/hardware/ti/omap3.git;a=tree and compiled Android image for Zoom platform here: [https]://gforge.ti.com/gf/project/omapandroid/frs/
Haven't got it working though. Actually I don't know if it's easier to try with the HCI commands and scripts found in the bts files or try to get the fmapp working.
Hi,
you can test it self... milestone is rootet look here

It wont work on milestone, hardware is missing some parts to connect antenna to the headphones. http: and-developers.com/motorola_milestone:fmradio
That´s right, the Milestone/Droid not have some parts of reception and transmit modules, so, it´s quite a hard to get it work decently
I see this thread is quite old, but...

The MUIU app lack several things like auto-tuning so I would be nice with a better FM Radio app which supports RDS and auto-tuning!
I've released version 2.0.2 of the "Spirit FM Radio" app. See my sig for the details post.
The best support is for CM7 ROMs with the CM FM app. It may also work on MIUI ROMs as well.
My app supports RDS data on TI FM chips, and more basic functionality on Broadcom FM chips, such as used on the Leo/HD2. I intend to add RDS support for Broadcom with further reverse engineering.
The app is running well on my HTC Legend and Desire HD, and I think should., or I've heard does, also work on Leo/HD2 and several other devices.
Thank you for your app.it works better than the default fm app in hd2 that we have in non sense roms.

Thanks for your report !
If you are using v2.0.3 from the Market, and you have ADB on a connected computer you could ensure you have an SD card and try running:
adb shell touch /sdcard/fm_su
or from an on phone terminal emulator:
touch /sdcard/fm_su
This creates a file that enables this command in the code:
su -c "chmod o+r /dev/msm_snd"
The code then does an "ioctl" hack that can enable FM audio output on some phones. I needed this hack before CM was updated to do this internally for FM audio routing.
But it's possible you don't have a /dev/msm_snd pseudo-file and this hack won't work.
I might be able to find some other workaround for non CM ROMs.
Another trick for audio routing on HTC phones with stock or stock derived ROMs is:
adb shell "echo fm_speaker > /sys/class/htc_accessory/fm/flag"
or
adb shell "echo fm_headset > /sys/class/htc_accessory/fm/flag"
Use this to verify:
adb shell "cat /sys/class/htc_accessory/fm/flag"
I DO have this in the code, but it's possible the ordering of different audio routing methods is a problem.

Yes, I have it running on my HTC Legend with the Blayo ROM which is a Sense ROM derived from the stock ROM.
I should be able to get this app running on any Android 2.1+ device with a TI or Broadcom FM chip (or future supported FM chip) providing the following conditions are met:
(1) - I find some way to route FM audio from the chip to speakers or headset. Thus far the app only supports analog connections, but most (or all?) phones with a usable FM chip seem to have an analog connection. It might be possible in future to route digitally, or even to BT headset with the audio never leaving the combination BT and FM chip.
(2) - I find some way to control and read registers on the chip. Most phones seem to piggy-back FM on the Bluetooth HCI interface. Currently, my app, and the MIUI and CM apps, all use the "hcitool" command for this. AFAICT, none of the stock HTC ROMs has a working hcitool, and copying one from the CM ROM doesn't work. IMO, these ROMs do not fully support the Bluez BT APIs.
Version 1 of my app had the abiliity to run a daemon that directly accessed the Bluetooth library, which is a better way than running hcitool. Unfortunately, running the daemon seemed to require root/SuperUser and I'd prefer my app not require this, Furthermore, I could not get this to work on the stock or Blayo ROMs. It might be possible, but I haven't figured out how, and nobody "On the Internet" has figured it out either.
So for the Blayo ROM I found I could use a "btipsd_cli" command that also seems to be on the stock ROM. It's an ugly hack because my app "pretends" to be a human entering commands, but it worked, although with some occasional stability problems due to btipsd crashing. And BTIPSD* is Texas Instruments FM chip specific; it will never work on Broadcom chips. Perhaps there is some Broadcom command line utility or API that can be used; I haven't looked too deeply yet.
The iPhone uses a Broadcom chip and apparently has a "bcm" command that can control some functions. AFAICT, many people have wanted an FM app on the iPhone(s) put out in the last few years with this chip, but nobody has ever got it working. Broadcom apparently only supplies specs for their chip to their large customers. I can't even find a decent datasheet on foreign web-sites that contain other confidential type materials.
Beyond that I could possibly reverse-engineer the API that the HTC FM app uses, which seems to live in the android_runtime library. That would have the advantage of likely working on all HTC phones, regardless of chip. But I would very much prefer to control the FM chips more directly, using the BT / Bluez library for HCI access.
So hopefully, eventually, many more phone and ROM combinations will be working. I'm happy to work with anyone who might have ideas or time and expertise to try and help me hack these "secrets".
In the longer term, it might be nice if the Sony Ericsson proposed Android FM API gained some traction, but I'm not sure if other device or chip manufacturers, like HTC and Broadcom, will support this API.

I just purchased an A501, rooted it and am running the Alexander III rom, (very nice job on the rom!!!)
I was hoping I would get the bluetooth Headset HSP profile in the new rom but sadly it was not there.
A little research has shown that there is a Bluez driver plugin installed and various bluetooth libraries, my question is can I potentially just replace these libraries with bluez libraries from another rom that has the HSP profile?
I really need to get the bluetooth headset profile working on this A501, and am willing to pay a bounty for help in getting it working
Sorry to say, it doesn't work... as with most other Tablets.
Just using some libs from another ROM isn't going to work either, unless they are extremely similar... and all ROMs similar enough to try such a stunt are almost definitely broken as well.
Sorry, but you'll have to roll your own BT stack if you're desperate enough to try... I'm not gonna.

Still doing a little research on this. I discovered, in the Bluetooth folder, a couple of files pertaining to what Acer has deemed "black listed", which simply means, certain brands and models are not allowed to work with bluetooth. System/etc/bluetooth/
Also noted, if you modify the files, you need to make changes in a couple of other module files (android_bluetooth_ScoSocket.cpp). The info in the above files tell you where to look.
Not sure why Acer black listed those devices. Legal reasons maybe? Plain incompatibility? Who knows.
My dev skills, are not quite up to modifying .cpp files. Probably enough to muck things up really good Not to mention, I would have no way to test them. But when I get a chance, I'll see what's in them.
Of course most of this pertains to Auto pairing, so might not be of much use. As with the .so files in the Bluez folder, you'll need to de-compile them first to see what's in there.
Also, I saw some bluetooth apps onn the market that some folks had some success with getting HSP. Not the off/on widgets but an app itself. Might want to give them a try and see if you can get the headsets to connect.
Additionally, it seems bluetooth headset problems seems to be across all devices, and not just the a501, but Zoom, Transformer and Thrive as well. Hit and miss with what works. Most issues say the mic doesn't work.
I tried a couple of the apps with no joy on my plantronics earpiece but one of the widgets actually connects...for just 2 seconds...then disconnects...I think the capability is there and you are correct there is some file manipulation that needs to occur...
I have a friend in Egypt that is very good with android bluetooth, he is working on another project right now but when he finishes his current project I will send him these files...he might be able to figure it out ...
Hello,
does our device suppor ANT radio? maybe in some kind of custom rom/application?
thnx
You have any link or info on what "ANT Radio" is?
yes, this is a good site for additional info : http://runningdigital.com/2010/10/30/bluetooth-and-ant-sensor-tech-for-mobile-phones-today/
seems some processors are able with ANT radio , but must be opened with firmware/apps
from previous link :
Android Let me start off by stating that no current Android supports USB dongle-type adapters, like those available to iPhones. While this isn’t great news, I’m more keen on native support solutions anyway than to have something else plugged into my phone before every run. That said, to have native ANT+ support we need the right hardware and firmware specs. Texas Instruments is one of the first, or only, to supply chip sets for mobile phones that supports ANT+ connectivity. I say “supports” because the phone’s firmware has to be written to activate the ANT+ radio, and I have not been able to find an example of this yet. The Motorola Droid X contains the Texas Instruments ANT+ capable WiLink 6.0 chip, however it lacks the out-of-the-box firmware to make ANT+ connectivity possible. Even if you were to enable ANT+ by hack, there still isn’t an app in the Android Market that’s ANT+ ready. Bottom line, widespread Android/ANT+ solutions are going to take some time to be available. *EDIT Sony Ericsson is now the first Android handset maker with ANT+ connectivity solutions. On February 1, 2011, SE began rolling out firmware updates activating ANT+ hardware on their X8 and X10 family. No word found yet on compatible applications. ENDEDIT*
As new as it sounds, especially with something like the Erickson being the first to have it in Android, I kind of Doubt that the Desire-Z/G2 is going to have it.
Though if I knew what to look for in the DMESG output I could tell ya.
i have read om some other website that seems also some HTC desire series are able to have ANT radio, but seems HTC disabled it in the rom...
but cant find the link anymore

MAJOR EDIT TO THIS POST AS NEW KNOWLEDGE HAS COME THROUGH. (BUT YOU MAY KILL THIS THREAD AND GO INTO THE I9305 forum and go into the I9305 Tear down thread)
The I9305 may or may not have hardware capability for FM radio, But the firmware software doesn't have it installed. The funny thing about this is even the Optus Customer service and technical support are not aware of this, they do beleive they are supposed to have the FM radio.
MOBICITY sells it and there specs show FM radio and I even asked there customer service again and made them triple check and they confirm it has it and I seen a youtube video of the White version but this is from UK and its definitely having the FM radio app. So Maybe some developers can get involved or maybe not, If there is a 3rd party app around that will work in place of the Fm radio app then if it can be posted it would be great thanks. EDIT: Mobicity Now changed and said Because they are coming from Hong Kong there wont be FM radio Installed as per hong Kong Laws. Specs have now been changed on there site a i told them it was false advertising lool
Edit: Apparent Proof that FM radio is in some I9305 >>> http://www.youtube.com/watch?v=VGICeramJxc Look @1:14 4th column 3rd row you see FM radio app- I also messaged the guy and he confirmed it working, Edit: User Said he heard static, Then after more people interrigated him, he seemed to have changed his waysss and said he thought static meant Silence I then questioned him aswell but I basically called B S . In electrical terms static means Hissing/white noise/ Scramble. etcc...... He then questioned me as to why he had it pre-installed on his I9305 ... Apparent I9305??? Is it even a I9305 in the video Or a changed Build.Prop to show different Model number I9305. Can be done in 10 seconds. Cause why would samsung put the Radio FM app in it and its not working. NOT 1 Confirmed I9305 has the FM radio app. Except for that guy. Hmmm..u get my point now.. Anyway After he questioned as to y he had radio I told him to question where he bought it anyways that is the last i heard of him.
More Edit : We have a 9305 Hardware teardown thread, and as we are not hardware minded we cannot confirm 100% yet. Although we do know we have the a broadcom Chipset with the capabilities of FM radio, but the problem there is it is not linked up. So really then we do have the hardware but its not plugged in. Just like the I9300 has The broadcom one which is not hooked up and the Silicon labs which is hooked up, Now i dont think we could locate the silicon labs chipset on the i9305 board from a few pictures show.
SO far there is no 100% proof of this radio so untill then , I say it does not have FM radio. Unless some that knows chips and fm chips please go into the teardown thread and advise us so we may solve this query
As I said I have only seen 1 with the FM radio that you-tube link above shows it and I also emailed the user and he confirmed it working but then after more thorough interrogating the user changed the meanings of his words loll. Anyway Kill this thread. Come into the I9305 arena and go into the (I9305 Teardown thread) if you want to discuss this topic
Thanks for your research man. Unfortunately I'm not 100% convinced since I can't see that the phone is i9305 in the video (only the screenshot below which could be from another phone :/). But, I hope it's true, we just need more evidence and help. Did the youtube guy tell you what firmware he was on?
So you mean the original firmware of i9305 doesn't support FM, so even rooted and use Spirit CANNOT use FM radio feature?

If the hardware is there, then what we need is a kernel driver. Flashing a custom kernel (and/or ROM) with the driver, along with root/SU access should be sufficient.
Hypothetically, a kernel driver could be loaded without a new kernel, but practically it's quite difficult to do. In theory one could also poke the I2C or whatever controller, but that too is not easy.
Latest free release of Spirit is here if you want to help test: http://d-h.st/lfR
Anyone tries, please send me a debug log using Menu-> Test-> Email-> Logs. After 10-15 seconds press Send.

Edit: Proof that FM radio is in some I9305 >>> http://www.youtube.com/watch?v=VGICeramJxc Look @1:14 4th column 3rd row you see FM radio app- I also messaged the guy and he confirmed it working,

I watched some of the first hands on videos and saw the FM app, but no video I saw had somebody try it, that I can recall.
I was reading I think about the above person, and the story seems to be that they heard static and thus didn't really confirm full operation. They may have been in a bad reception area though.
Static is actually a good sign to some extent. It indicates the FM audio path is there and usable. And I think static is better than relative silence, which you might get when an antenna pin is grounded to disable all usefulness.
It's possible that a software controlled switch exists for the antenna connection, or a hardware jumper. It's also possible that US variants won't have the Silicon Labs chip installed, but other variants might.

Sent you the logs (with signature "Shujen Chang" in my email).
P.S. I'm using Hong Kong version of i9305.

Got it, thanks.
I see something in your log I hadn't noticed before, but it's also in the other logs too:
10-25 22:04:21.955 I/dalvikvm(16354): DexOpt: not resolving ambiguous class 'Lcom/samsung/media/fmradio/FMPlayer;'

What this means is that the Framework code is there for FM. If there's a chip and we can load a driver, then there's a good chance the Samsung GT-i9300 or GT-i7100 FM app would work.
But we're no closer to knowing if the FM chip is there. Here's the teardown thread in progress: http://forum.xda-developers.com/showthread.php?p=33275259
