I just got an S3 and I'd like to ask if it is possible to listen to FM radio over Bluetooth.
i connect the standard headphones to enable the FM radio and the only option is to switch output between the headphones and the loud speaker.
I've seen cheap chinese android phones doing that, there should be a way.
Any help would be greatly appreciated, help me avoid selling my new toy
Sorry to say but it won't work. The reason (as the app itself already accurately describes in the error message) is that your headphone's cables are used as an antenna for the phone's FM receiver.
FM antenna's are actually quite big (at least compared to other antennas) even when using the so-called fractal design because they use a very slow (roughly 80 - 110 MHz, compared to e.g. WIFI's 2400MHz) frequency. To save space, Samsung moves them to the hedphones on all mobile phones I know of.
I don't know if it still works on S3 (never tried) but on the S1, if the station is broadcasting with enough signal strength, you could cut off the plug of old broken headphones and plug it into the phone to use the radio.
Afaik Spirit FM (now paid in all versions) can override the requirement but you'll need to press your finger to the jack so you can receive anything... pointless.
Alternatively you could use an app for internet radio such as TuneIn; most radio stations (at least all around here) provide web-streams for on-the-go radio listening. However you should make sure you got a decent internet flatrate, I managed to chew through nearly 4GB just with music streaming this month.
Most countries seem to have abolished mobile data flatrates.

The OP understands that the phone needs the cord to act as an antenna. I think what they simply want to know is if the phone can then route the sound to the bluetooth device instead of through the speakerphone or the headphones.

d4fseeker I understand that the headphones should be connected since they serve as fm antenna. What i want is to listen to fm stations through bluetooth while the headphones are connected as bigb25 says.
TuneIn is not a solution for me since some stations I want are not available and cause I am a hiker internet is not always available where I go.
Maybe there is a fix or a different radio fm app?
OK quick test... plugged in 3.5mm - 3.5mm jack lead into headphone socket to act as the FM antenna and started the radio, selected sound to speaker and all worked fine. switched on Bluetooth headset no sound in headset, switched off sound to speakers still couldn't hear anything. Unplugged patch lead (this ends radio anyway) played an mp3from music player and sound returned to BT headset.
So unfortunately the answer is no you can't, as soon as you plug the anything into the headphone jack it cuts out the sound to any other device.
This may well be a mechanical switch within the headphone socket and so unlikely that there's a get around in a custom rom....but then I know nothing about roms

The latest Free version of Spirit can always be found at the top of post 1 of my Q&A thread. See my sig.
My cheapest ($80) test phone gets good audio AND RDS with no antenna. Ironically it's the best of 12 operational test phones I have. It's a Samsung GT-i5500 with the great, sensitive new Broadcom 4330/20780 family of chips.
But yeah, my Galaxy S and S2 don't do very well with no antenna. My Galaxy Note does better. Haven't heard from anyone with an S3 yet. They all have the Si4709 FM chip, which has positives and negatives. Internal circuitry etc. makes a difference too.
And I can thank the very positive sales response I've had from S2 and Note owners for being able to buy these expensive devices for testing. I'll do everything I can to make Spirit run well on S3 and hope to buy one soon.
I have yet to find a phone that does FM over BT, except for a strange very low quality mode I have working on some BCM 4325 based devices.
If the FM can be done in the digital domain, instead of the more common analog, then in theory it should be possible to do FM over BT.
But then again, in theory the Galaxy S and S2 hardware are capable of FM record (digital). Yet the audio libraries don't seem to support it, and I think it'd be a major/infeasible job to hack the libraries for it.
The Note and I think the S3 can do FM record with stock audio libraries. So I think FM over BT on these devices is feasible, at least with stock ROMs and/or using stock libraries.
But on non-stock ROMs like CM9, the Note seems incapable of FM record.
Basically, if the stock ROM and stock FM app don't support FM over BT, then I think it's not EASILY possible.
If it could be made to work, there's no reason why a phone couldn't have a wired earphone plugged in at the same time that FM goes over BT. This might "confuse" the audio system though, which usually sends audio over a wired headset if one is plugged.
Then again, it's also possible to have a plug that's partly inserted (or maybe even wired creatively). Enough for antenna but not enough to push audio through the wired headset.
Thanks mikereidis.
I tried the free version, it plays only when the headphones are connected.
Do you think you could look at the possibility to send output to bluetooth?

This dual active android phone does it: Star B79 Android 2.3.6 MTK6575 Smart 3G Phone 4.3"HD. I can not insert link cause of the ten posts limit but you can find it at aliexpress website
A colleague has it and I tried it just now and the quality is superb. And it is much cheaper comparing to the 730 Euro I gave to buy the SIII (greek retail price 32 GB version)
Actually this was the reason I switched from IOS to Android I mistakenly thought it was a default option in Android.
Also my ancient HTC diamond could do it with the help of a bluetooth utility but it woud often crash and quality was not good.

Yes.
I have one person reporting success with my app on GS3 on CM9 June 19 now.
It only works one time though, then requires a reboot for the 2nd time.
This was with an experimental release I haven't made public yet.
I hope GS3's will be coming down at least $100 over the next month. $700 is pretty darn steep, even if it's got a leg up on the One X and One XL I bought recently for 570 and 500.

That's very interesting; thanks for the info.
There are a variety of relatively inexpensive Chinese devices that have unique qualities, such as FM on an Android tablet, or digital TV tuner, or FM transmit I think.
But these devices are not widely available, or popular I think, in most Western countries. Information, source code and custom ROMs can be difficult to impossible to find.
As for Android: the audio systems can be kind of a big complicated mess. I don't think I've ever seen a single phone with an audio balance setting, among other things. But at least some Androids have "over the air" FM, whereas iPhone's have never had FM, despite years of rumors.
i am thinking of using one of these dongles though I doubt about the quality

Kind of a drag to have a dongle hanging off though, in addition to the wired earphone for antenna.
There's been a lot of praise for the Sony MW600 Bluetooth stereo headset with built-in FM the last few years. Under $40 on EBay now.
I just ordered the apparent successor, the MW1 for $120 plus shipping the other day. It even has a music player built in, besides the FM and BT 3.0 support.
I need the A2DP headset because I think I'll be able to support FM over Bluetooth on some devices in the next few months, and I need something to test with.
MW1 seems interesting with many features but the price is ....

Not an exact solution, but you can get bluetooth headsets with built in FM radio.

The headphone jack has a part that senses when a headphone is inserted (the metal
in the headphone plug shorts it. It seems like you could make a plug that connects
to the metal of the ground pin (for the radio antenna) but isn't "inserted" so the phone
won't disable using BT.
Anyways, only i9300 will support FM, there is no way to get FM working with the Broadcom
chip in the US S3's. http://forum.xda-developers.com/showthread.php?p=31576462#post31576462
I use a sony ericson bluetooth headset that has built in fm radio works well.
Model MW600havent priced them in a while,should be under $50 by now.

Hi,
I don't know too much about bluetooth, but I guess I assumed that these things were usually backward compatible. I bought a Samsung HM1100 bluetooth headphone which is BT 2.0 for use on my Palm Centro (don't laugh; it's ancient, but I like it) and for Skype on my SGP 4.0. Paired right away with my Palm, but my SGP can't see it. I see in the documentation that the SGP has BT 3.0, but - as I said - I thought that that would also work with 2.0 (also seeing that they are both Samsung products). Does anyone know if the SGP can not use BT 2.0 devices? If it can, any ideas about what I might be doing wrong?
Thanks.
I use a LG HBS-700 which is BT 2.1 just fine with my SGP 4.0 and honestly I can't see why your pairing wouldn't work.
http://en.wikipedia.org/wiki/Bluetooth#Specifications_and_features
From what Wikipedia says BT 3.0 is just higher data transfer which probably has nothing to do with low transfer rate devices like headsets. Anyway, I can confirm that the Galaxy Player 4.0 can use BT 2.1 so...I guess check your manual and make sure that you are properly pairing the devices. Obviously you've gotten it to work with your Palm, so the same procedure should work with the Samsung. Why isn't it? Meh, Android can be flaky sometimes. Every so often my headset won't show up so I just power it off then on again and I'm good to go.
Sorry, that's the best I can think of.
Is anyone aware of any mods that support bluetooth low energy. I'm really interested in getting a sports tracking wristband but every one of them requires BLE to sync to phones. I've read that android 4.3 will support it but I doubt our phones will ever see that officially.
Check out the "UP by Jawbone" in the accessories section. There's some discussion there regarding these fitness bands
I've been involved in that thread. It seems that the only android devices officially working with these wristbands through bluetooth are S3/S4/Note2 as Samsung has done their own work to get BLE working on these devices. Just wondering if there are any mods I'm not finding through search out there that would work on other phones.
I'm not sure what to tell you. Hopefully somebody else chimes in...
I know the up syncs thru headphone jack. I also know that the Bluetooth stack used in our phones is lacking...
Have you tried any AOSP ROMs ?
No I haven't made the jump to try out that side yet(I'm pretty attached to Sense's Car Mode vs other apps lol). Possibly will when 4.3 comes out. Especially with the upgraded bluetooth stack.
So now having had a chance to take a trip in my truck I was so pleased to see how much better 4.2.2 is with my stereo.
Here is a list of what now works that didn't with 4.3
1. BT Metadata now pushes title and track etc.. from my music apps to my trucks touchscreen
2. Stereo was 100% instead of 75% in announcing an incoming text and reading to me if I choose to on touchscreen
3. I can finally!!!! Hit reply on stereo from text and then speak and have it send without having to touch my phone or even choose template replies if i don't want to have it dictate
So glad to have this all working and hope others see these advantages as well

Hi there,
I hope I'm posting this request in the right section.
I have recently bought myself an Xtrons TD730a Double Din Head Unit, I would post a link to it but unfortunately I am unable to as the forum won't let me. You should be able to find the unit in question with the help of google though.
On the whole I've been pretty happy with the device. The main downside I have discovered though is that it appears to be running a rather cut down version of Android 4.1
It is unable to communicate with my Bluetooth OBDII device, which having read through a few of the other threads on here seems to be a common issue with many of the Android Car Headunits.
The other, more annoying issue I've noticed is that when I am streaming music from my home server over 3G, it doesn't seem to support gapless playback when changing to the next track or Audio Chaining or whatever it is known as. I use exactly the same apps and set up on my LG G3 and gapless playback works fine on that.
From what I can gather, the necessary APIs to support Audio Chaining were added in to Android API Level 16 which was introduced around the time of Android 4.1 so this Headunit should support it.
I'm wondering, if the Headunit is running a rather cutdown version of 4.1, is it possible that Audio Chaining support has somehow not been added to it's supported APIs?
Is there a way I can check if this is the case? And if so, can I get them added in somehow? I'm guessing that a good place to start would be if there is a root method available for this device?
I hope it was OK to post these questions here. Please let me know if I should have posted them elsewhere.
Cheers,
Jim

Even though its an 7 inch screen it is the same as the AN21 head unit internally. So it doesnt support obdll over bluetooth. Try getting the wifi version that it works. Try the same rooting method as that head unit.
@ little off topic question
Im sorry I do not have the information on that for you but it shocked me when you said that it didn't work with your phone over bluetooth . I was thinking about buying this model and want to make sure that the Bluetooth is able to stream my music and also make phone calls from the dash !? Is that possible with this unit ?
Another question I had is about the sound quality
The watts are not listed online so does it get loud and clear or do you need an amp with this unit
Again sorry I couldn't help ( sorry for asking a bunch if random stuff )

Thank you so much for pointing me in the right direction :good:
I've had a good read through the AN21 head unit thread. I've ended up upgrading the system software to version 2.8.3 and I've also managed to root the device.
The result is now that I am able to play my music over 3G without there being any annoying gaps between each track.
As you've mentioned, it still doesn't support OBDII over bluetooth and this does turn out to be a hardware issue rather than a software issue. In fact, the software itself does clearly support OBDII over bluetooth, it's just the hardware version of my bluetooth controller that doesn't support it.

The head unit does connect to my phone over bluetooth, I never said that it didn't. I was referring to a bluetooth OBDII adapter (for reading out diagnostic information from my car's ECU) that does not work with the head unit over bluetooth.
I've not actually attempted to make or receive any calls over bluetooth, or to stream any music via Bluetooth, but it is my understanding that the head unit does support these features.
It is probably a good idea to have a proper read through the"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit [ROOTED] thread available on here in the Android Development and Hacking --> Android General section as it seems as though people have had different results with regards to sound qualities depending on which software version / MCU version they are running on their unit. For what it's worth, I've left my MCU version untouched as it looked as though it was a whole different ball game to change MCU versions as apposed to simply changing the software version.
I can't remember off the top of my head what the speaker wattage outputs are, I seem to remember something around the 45X4 mark, remember those are peak ratings. I do have an amp running a sub woofer in the boot of my car but the rest of the speakers, which are just the standard speakers that were supplied with the car, are powered directly off the head unit.
I've got to be honest and say, I don't think they go as loud as they did with my previous head unit, a Sony MEX-BT3100U, so I will probably look at amping them at some point in the future, probably after replacing them with some good quality aftermarket speakers.
