FM Transmitter

Our GSII comes with a built in FM Transmitter/Receiver chip. I haven't seen a link on this. Has anyone unlocked the potential of this hardware feature yet? I would love to be able to transmit an FM signal.

Hrmm really? That would be too cool for school!

Here's the tear down of the phone. http://www.ifixit.com/Teardown/Samsung-Epic-4G-Touch-Teardown/6481/2
The phone has the Broadcom BCM4330XKFFBG 802.11 a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0+HS and FM Transceiver/Receiver. Not sure if we're going to have to be rooted to utilize this hardware but we have the internals to broadcast our music to our cars with our phones alone.

Here's more info on the specific chip in question http://www.broadcom.com/products/Wireless-LAN/802.11-Wireless-LAN-Solutions/BCM4330

it all boils down to if the transmitter is actually connected to the chipset
the evo also has an FM transmitter but there really wasnt any attempt from anyone to get it working.

My galaxy s II came with an fm receiver app that works nicely. idk if it would work on the epic

Hmmm....think of the possibilities. With a lot of states requiring hands-free cell phone operation, could this be made to work as hands free device for your vehicle? It would definitely save us consumers from having to buy yet ANOTHER piece of hardware for our phones, which can damn near drive our vehicles for us anyway.

Are there any in the market that has been tried?

I've tried spirit FM and it did not work, I wasn't really aware how much I used it, till I got this phone.

dont give up on this, the potential is amazing!

Noone has gotten fm transmitter stuff working for any phone with these chips, even og epic had the chip capable of this. Probably the feature cause interference so it was not enabled. It would be a killer feature and u would imagine one manufacturer would enable it if they could. So native something preventing then if doing that. I remember long time ago there was lg fusic flip phone that had fm transmitter on sprint, haven't seen any phone with that after that.

[Q] galaxy nexus has fm radio device? or not?

i cannot find it in system features

No, there is no FM radio
Sent from my Galaxy Nexus using Tapatalk

Actually there is a chip (at least in the Verizon version) that has an FM radio in it, but there is no antenna and no low level software to run it.

The Galaxy Nexus has a Broadcom BCM4330 which features an FM receiver and transmitter.
It seems there's no antenna wired nor driver access, though.

Tune-In Radio (free app on the market) had the local stations I used the FM antenna on my old phone to listen to, so I haven't missed it on GNex yet, perhaps that is an option for you.

The Nexus One had a Broadcomm BCM4329 and someone figured out how to get FM. If i remember correctly, it needed headphones plugged in because it used the wire as an antenna. It was in Cyanogen roms, and probably others as well. So, hang on, surely the chips aren't that different and surely someone will get it working sooner or later.

I still miss true FM. I use Tune-In daily, but the cons are: 1) data usage 2) any broadcast of protected content, i.e., sporting events, are typically not streamed.

FM Radio in Galaxy S3?

Can someone test this app and see if it works? I saw someone mention the FM Radio app in the U.S. GS3 is missing.
http://forum.xda-developers.com/showthread.php?t=1059296
You will need to plug in a pair of headphones to see if it works.
Our kernel indicates the CDMA S3 implements a BCM4334 much like its international brethren. This chip provides:
-2.4ghz and 5ghz WiFi a/b/g/n
-BT 4.0 + High Speed
-WiFi Display
-WiFi Direct
-FM Radio

Can someone with S III please try using Spirit FM Unlocked, it is an app that enables FM radio on some handsets where the carrier disabled it or did not include a radio app even though the hardware is there. As pointed out, headphones need to be plugged in as the antenna. If Spirit FM does not work yet...Mike the dev might be able to make it work, provided S III has an FM radio inside. That dev works miracles so if he can enable FM on SIII on VZW I'll def. buy the Spirit FM radio app.

Didn't work for me
I downloaded the 'Sirint FM Unlocked Light' and it didn't seem to work on my rooted S3 16gb phone. It may take some settings changes but I didn't have a clue in the settings what to chance.

Try the settings changes as the page describes. Primarily the Audio Output setting.
A "No Audio" problem is common. If the app seems to tune, show signal strength and/or show RDS data, but no audio is heard, try configuring the Audio Method. Tune to a strong station and select each Audio Method in sequence until sound is heard. If no method works, your device is likely not yet supported, sorry...

Broadcom should be the right setting (sorry, BCM4334 is a Broadcom chip, should have mentioned that).
Did you try tuning it to a station in your area?
Negative is probably normal, I'd imagine that's measuring power in db. Negative just means below 1 Watt. Extremely negative (-120) means just noise (thermal noise). But noise is a good sign! I hope.

Don't know. But if you read the dev Mike's thread on Spirit FM you will see that if ANYONE can get FM working, it is him. He single-handedly reverse engineers the drivers for each handset. LOL he must have a lot of phones. Once he has an S III... he will let us know..

Yeah, none of the stations worked. I thought negative was odd because the Youtube video I saw of the app working did not have negative numbers.
EDIT: My Bluetooth actually turns on by itself when I change it to "Samsung Broadcom." Could that have to do with Bluetooth being on the same chip?

Yeah.
I wouldn't be surprised if the App author would have to change some things for it to work. It's probable he's interacting with the IO layer directly, in which case the IOMap could, and likely would, have changed with the different architecture.
The key thing I wanted to determine is if the BCM4334 FM Radio circuitry is even hooked up in hardware. With the move from Exynos -> Snapdragon, the board design would have changed too.
My fear is they didn't connect it up for whatever reason.

So do any phones on Verizon, Sprint or TMobile have FM tuners? This is probably disabled by the carriers if they don't. Seems like US Cellular doesn't care as a girl I work with has an HTC phone through them with FM radio. Maybe the US Cellular version of the SGS3 will have it and developers can find a way to port it from there if it's not disabled in the hardware.

Odd, none of those pictures show a BCM4334. Or any other WiFi chip.
I know the 8960 doesn't have it built in....

Does this device have a Qualcomm combination chip for FM/BT/WiFi ?
Or is it a Broadcom BCM4330/4334 ?
Someone sent me a debug log from an unrooted SPH-L710 and I see evidence of Qualcomm FM, but there are Broadcom files too.
The Spirit FM June 28 test release link and info are here: http://forum.xda-developers.com/showpost.php?p=27996724&postcount=3894
It's now working on my AT&T HTC OneX(L) which has the same Qualcomm SOC as the US S3, and which has Qualcomm FM.
If you are rooted, please try the June 28 test and send me debug logs with Menu->Test->Email->Logs.
Thanks !

Yes, I'm REALLY, REALLY hoping that Samsung was strong enough now to tell the carriers:
"No, we're not going to remove FM this time. Don't provide an app if you want, but the FM hardware stays, and there are only 2 HW variants."

I rarely look at the SOCs too closely, but it appears the MSM8960 has integrated "digital" Bluetooth and FM, AFAICT. An external WCN3660 is sometimes used for analog.
Otherwise, if the antenna pins are hooked up, we may have FM. Audio should be digital and internal. Heck the Qualcomm chips allegedly support an "internal antenna", but not sure if that's on the chip.
The most important FM file on the OneX LTE version is the driver:
/system/lib/modules/radio-iris-transport.ko
It's not on your ROM. Kernel differences might prevent just using a file from another device.

When I tested the June 28th release it said "Fm: QC OEM," something I had not seen on previous releases (I'm guessing "QC" means Qualcomm).

FM Radio.. anybody

Does anyone know how to enable the FM radio inside the G Pro (assuming ATT kept it inside). I know from past smart phones that FM radio ability can lay dormant inside the handset until software enables it. This was the case with a windows phone recently. I do know that the international model had the FM radio. I need to know if ATT removed the FM chip or disabled it with software. I hope some one has root ability to offer some type of FM radio on this device (or using the Bluetooth radio as FM). Thanks for any help!!!!

Default settings are usually best.
It's more likely to work if you're rooted though.
If there is no FM driver in the kernel, an alternate kernel may help.

All recent modern phones have FM tuners built in to them. They can utilize the headphones as a receiver. The problem is AT&T has disable the tuner so we cannot use it without a special driver. @nerdyblonde what do you think could you guys pack this into Blisspop?

Any way to retrieve the necessary programming?

If the FM antenna pin is grounded, as it is in most "Western world" phones now, nothing short of an extremely expensive and/or "heroic act" will fix it.
Do you know, or can you afford to hire, someone with access to thousands of dollars worth of micro-soldering and multi-layer PCB reworking equipment. And the skills to use them ?
In 4 1/2 years devoted almost exclusively to FM radio on Android, I have only ever heard of 1 successful case: A Chinese Android tablet that had an easily accessible antenna jumper. He used my app but we could never enable audio, which can be another huge hurdle.
Vast majority of devices use a PCB ground trace, that can be thick and very difficult to break. Then you'd attach a wire to a 75 cm or more long antenna/headset cable. Never mind the few coils or caps etc that need to be installed too.
TL;DR: Forget about it and get a new phone with stock FM, or a BT/FM headset like Sony MW-1.

NextRadio through phone speakers

Anyone know of a workaround for NextRadio's requirement that headphones be plugged in before I'm allowed to play through my phone's speakers?

This is correct. It's a limitation of physics: you need an antenna of a certain length to receive the radio signals.
