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.
Here's the tear down of the phone. http://www.ifixit.com/Teardown/Samsu...eardown/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/Wir...utions/BCM4330
Will we need an app or root and a kernel or something?

Looking into this right, it seems like the stock kernel comes with it turned off but I am compiling a new kernel with support, let me c if it works. watch for zedomax v4 soon...

this would totally make this an epic phone!

if it is possible you will then need an app that can broadcast

Spirit FM Radio?

I think sprint FM radio is a Data based streaming application. Has nothing to do with actual FM reception or transmission. As it relates to an app that exists for the international GSII, are you familiar with the name of it? I just want to commend Zedomax again for his tremendous efforts and early historical success as it relates to this device. Thank you very much sir.

(Discussion) best radio for T-Mobile

Anyone have any thoughts? I've been rocking la2, but I'm interested to see if anyone thinks anything is better...
Sent from my Galaxy Nexus using Tapatalk 2

I've been much better off with UGLC1. Switching over from XXLA2 dramatically improved my signal in several places.

I'm going to have to agree UGLC1 with matching ril is best one I've cone across

Excuse my ignorance but does the stock radio not work well with T-Mobile? I am coming back to the States in a few weeks and would be sorely disappointed if that is the case. Will I have to root or custom just to have decent service in the States?

Depends what you mean by stock. Each build variation usually has a different radio being that they are region specific build. I know yakju is packaged with xxla2 which is what most roms have by default and I think uglc1 comes from the yakjuux build

There will not be a general consensus. As with all radios, it really depends on where you live in the US as to which one performs better.

Though it seems like at least so far, there is some consensus...

Not only that. All of these and more:
Network congestion
Weather
Distance to antenna
Terrain/buildings/obstacles
Usage patterns
etc.
That is why it is so difficult to take someone else's suggestion for a radio.
Try a bunch out for a few days and see which one works best for you. And don't use speedtests. Use your perception of what works best for you and what doesn't.

Is that a streaming radio app? As far as I know the T-Mobile S3 does not have a FM radio thus having an FM radio app would not prove to be useful.

no sound on call with the new UVLH1

i'm sorry but anyone noticed the issue of the new UVLH1 update or i'm the only one? when i make a call i have no sound on the phone neither to know that i'm connected with the other side nor to hear him?? even if it's not all the time but it's annoying sometimes to make 3 or 4 call to have one!! anyone have the same issue or a solution please?? i'm on UVLH1 rooted

Might be a bad install. Try wipe cache and fix permissions
That will do. If not reinstall and so the wipe again

I had this problem when using my Plantronics Voyager Pro. To fix it I wiped data from all system apps involving blue tooth.
Sent from my SGH-T989 using xda app-developers app

still nothing
i tried almost every thing, i tried to wipe cash, to do a factory reset, to reinstall the rom, still the same problem

This problem happened again for me as well, but only on cdma. Try switching your phone to gsm only and see if it functions. That is what seemed to fix mine. (I know, not really a fix. I am just curious if the problem is a bug in the new radio.)

That post perfectly describes my device. Now, try going to Wireless Network settings and select Gsm only and see if it stops hanging on connect.

i prefer not to do that, i'll lose my fast connection, i prefer to downgrade to 4.0.3 rather than to do that, but only i'm worried if that will happen to me again when i do that

You need a custom recovery and you need to know how to use it (the recovery you have).
Again, towle has a sticky with mirrors MANY helpful downloads. a flashable zip of uvle1 radio was in it the last time I checked.
If you don't know how to check if a flashable radio has a ril then flash the radio, THEN your ROM. Custom ROMs tend to have custom rils and it is best not to overwrite them.

As an end note, I'm using lh1 and have been on every ROM I've used (tried too many to remember), not everyone has issues; it may depend on the area you are in.

I agree!!!!
I just Re-flashed both my phones to GINGERBREAD 2.3.6 UVLDE That I got from Here: http://www.sammobile.com/firmware/?page=8&view=4798 using the ODIN software and a great walk though found Here: http://androidforums.com/samsung-galaxy-s2-t-mobile/628449-how-odin-any-stock-rom.html
So far, we haven't had any calling issues as of yet....Plus, the phone is super fast again!! I noticed that with ICS on the phone, and Factory Reset with nothing on it, My RAM was tipping between 500-600 MB of use!! and now that we are back to Gingerbread, it's at 295-340MB....Which is a HUGE difference!!!!!
Let's hope, that maybe it might be defective SIM cards or chips like you said, but I am also tired of wiping these phones and starting all over again!!! I think Im gonna stay with GB for now......It's woking as intended anyway...

I'm having this issue where when i make or receive a call at times there is no sound and either party cannot hear. This happened to me on GB too. After monitoring it for a long time, i figured that it only happens when inside home where i get poor reception and not outside or places with good reception.
When i'm at home i usually get 1-2 bars of signal. Often, when i get a call and i don't get any sound, i look at the signal strength and it is at 4 bars but as the call disconnects it drops back to 2 and then if i make or receive the call then it goes fine.
I searched around the net i see this issue is with S3 users too, when they have poor reception they do not get any sound on call. I'm thinking that it has to do something with the radio hardware or holding reception in low reception areas.

iFixit Teardown - FM Radio

I was on this site looking at how to take apart the Nexus 7 2, and on this page:
http://www.ifixit.com/Teardown/Nexus+7+2nd+Generation+Teardown/16072/2
It said "Qualcomm Atheros WCN3660 WLAN a/b/g/n, Bluetooth 4.0 (BR/EDR+BLE), and FM Radio Module".
Does that mean this device can support FM Radio?

I saw that too, might be pretty cool. It might have the receiver and no antenna though.

I feel like that's more than likely the case. Which is a real shame. Maybe it's possible to use the headphones as an antenna who knows.

Oh man that would be such a cool option. I use my phone all the time just to listen to the local morning show. If it would work with the Nexus, that would be one more reason to buy this for me.
I am still on the fence about buying one, at least for a couple of months, I want to wait unit some good reviews come out.

Isn't that exactly they work? My phone has an FM receiver and requires the headphones to be plugged in before the app is turned on and uses them as the antenna.

I d/l the free spirit FM app, bit it just causes my tablet to reboot. That's the thread you would need to follow though.
Sent from my Nexus 7 using xda premium

I'm pretty sure there is no way that Google allowed the FM antenna pins to be connected anywhere but shorted to ground. Like any Nexus device, if it was FM capable, I'd be thrilled and would rush to get one ASAP.
For this chip, the kernel config needs to include radio-iris into the kernel itself (not a module). AND radio-iris-transport.ko needs to be a module, it can't be in the kernel like radio-iris. Strange, but so. You can insmod the ko, but the official method is to run this as root:
setprop hw.fm.mode normal ; setprop hw.fm.version 0 ; setprop ctl.start fm_dl
If the ko isn't loaded the phone will reboot due to stupidity in the kernel driver.
With the driver loaded properly, Spirit should detect the FM chip OK. Most likely, RSSI signal strength at top left will be negative or zero.
On the IMO very tiny chance RSSI is 10 or higher with a wired headset plugged in, and the frequency set to a good channel, then we can worry about making audio work.
The only Nexus device EVER released with FM hardware capability was the old Nexus One, based on the HTC Desire. And even that required a custom kernel at minimum to get audio.

Any updates to this?
