FM Radio - Hardware on the Vibrant?

I see the specs all over the Net for the T-Mobile Vibrant say there's an FM radio and that for the Samsung Galaxy S generally there's one too.
Is that accurate, is there FM radio hardware on the Vibrant? (I am not talking about software that provides Net FM radio, I am referring to the hardware radio.)
On the Touch Pro2 (TMOUS) it came without the FM radio app to use the hardware radio that was in fact on the phone. Is it the same with the Vibrant, where we simply need the FM radio app to activate the hardware radio?
Or does the Vibrant NOT have a hardware FM radio?
If the FM radio is on the motherboard, anyone know where to get the app or software to make it work?

I don't have much info for you, but a few of the reviews I remember watching on the net last week have said that the international version does indeed have a built in hardware FM tuner (you have to make sure to plug in headphones though, they act as your antenna). I even saw a demo of this app. I don't remember if this was on the international Galaxy S or the ATT Captivate.
So unless T-Mobile totally removed the hardware chip (I wouldn't say to be very likely) it should still be there. Hope this helps.

I don't know for sure but based 0on what I have read it seems like the Vibrant does have the hardware for a radio...and as of now there rumors that 2.2 will bring out the fm radio to its fullness but nothing has been confirmed as of yet.

Check tunein in the market no need for fm radio

Check the think tank for this. It seems the Vibrant has the hardware as part of the GPS chip (correct me if I'm wrong). People are having a hard time getting it to work though. I'll try and find the link and post it.
I found the link, but i can't post it because i don't have rights.

Would be interesting if the GPS chip was a full software radio. Scan just about any frequency...

True, but an FM radio would probably use less power.
Not a big deal for me since I have a tuner in my BT headset, but it would be cool if the Vibrant had one.
I thought people were trying to figure it out in the Dev board without much success.

Yes. For the Atheros chipset on my wifi card, the Linux kernel has the complete source code. A few simple limit changes in the reg.c (if I remember correctly) lets me scan from nearly from 2.1 to 2.8 GHz. Unfortunately, I haven't figured out how to change the channel spacing, modulation type and all that.

is there a way to use to fm radio.apk from the i9000?

hahaha. I gotta say, that would be a pretty stunning achievement if you could get that working.

I don't know really but 2 weeks ago I flashed Galaxy S i9000 Rom on my Vibrant and when I tried FM Radio first it gave me "Unable to switch on Radio" then I managed to switch it on but I only heard shshsshshshshshshs and when I shift the tuner to another band nothing happens !

How did you manage to switch on the radio? Just wondering may be that will give some clue. Also could you confirm if it asked to plug in the head set before it produced static.

Indeed, how were you able to turn this on? Though, I am more interested in the transmitting side of having an FM Radio built in, but receiving might be neat.

Actually I used a custom made update.zip file to enable Arabic support on my vibrant (which it's inherited from i9000 ROM) .. Anyway after applying the update.zip I saw FM Radio icon in application menu so I clicked it and it loaded and asked to connect the headphone to use it as antenna so I connected the antenna and that message disappear. Then I clicked on start Fm Radio and at the beginning a message appeared telling me cannot switch on FM Radio so I clicked it again and again and for the forth time it worked ! I started to hear the (shshshshshsh) sound but unfortunately changing the frequency didn't show me anything! Maybe because it can be used only in US and I'm from Bahrain so maybe that's why it doesn't work !

Is the bahranian vibrant different from the US version? When I load eugene's "froyo that does not brick", I get nothing (i.e. no static). Additionally, headphone logic is reversed, so I only get the "please connect headphones" message when they are already in.

Tune in
Tune-in I ve found to be the best and most reliable Also it uses very little power if you are on head phones

[Q] FM Radio??

Hey all,
I saw an article just now, where the Droid 2 was rooted and the Droid X's FM Radio app was installed, bringing glorious FM Radio to the D2.
It reminded me; isn't the Galaxy S supposed to a have an FM radio built in? Has anyone been able to get an FM Radio app installed and running?

It's physically not present. The FM radio on the the I9000 and other international variants of the Galaxy S used the Broadcom BCM20751 chip, which integrated BT/FM/GPS. This was replaced in the US versions with the BCM4751, which doesn't have FM.

A little more information
I'm not sure of the actual chip being used but after unlocking the secret menus as discussed in another thread there are settings for fm radio audio. logically thinking, if verizon and samsung built this phone to not have fm radio why would they waste time writing that code ???

That's not logically thinking, that's wishful thinking..
The didn't write any additional code, they reused the existing code from the i9000, and then hid the options that were irrelevant, to keep from confusing people. You don't think they start from scratch for every Galaxy S device, do you?

Fm radio on any vzw phone is wishful thinking. Moto must have had to pull every string they had on the droid x to keep fm radio. Its possible on the droid 2, once you root (that's not an accident). In the past, vzw has even forced manufacturers to physically disable radio in the phone (htc). They can't track (and thus charge) your fm radio usage. So they try and force you to dump money into their worthless, overpriced v cast crap. And when tiered data plans get here, jackpot!
Vzw is a scheming, horrible excuse for a carrier. The ONLY redeeming factor is the network.

The BCM4751 is a dedicated GPS chip, which also is used on the I9000. There were early, erroneous reports that the internationa I9000 used the combo BCM20751 chip, but I believe they were debunked in threads about that phone here at xda.

Umm... seriously? Just take one look in the Android Market and you'll find probably hundreds of radio apps. Just because this phone doesn't have a physical FM tuner in it doesn't mean that Verizon's scamming everyone.

That's just one benefit of android being open.
And why would a carrier ask a manufacturer to physically disable fm radio on a phone that had fm radio on all other carriers (ex. touch pro2)? Why would they disable fm radio in the droid 2 when it has the same hardware and rom as the droid x?

Nope, i've read on multiple places that Motorola has disabled the hardware that gives you the Radio feature and nobody has found a way to enable it through hardware mods.

as much i know u have to modify the mother board, last i check we do have fm receiver but antenna is not connected to the outer body or some thing and in order to to make it functional u have to do two things.
1. Modify ur mother board (connect the antenna)
2. Drivers for ur current operating system.

It's also a BGA package chip so if that pin isn't connected then we're surely SOL.

The pin is not connected.You can refer to Spirit FM radio thread.It had been discussed.

This thread is named like a tutorial, when it's a question. That's no good.

i looked at the thread and learned that, Atrix will not play fm radio, NEVER :banghead:
Sent from my MB860 using XDA

Moto's original release specs at CES before the phone was available said very clearly internal FM radio.
But the Broadcom spec says FM TX and RX, meaning the chip supports both FM reception AND TRANSMISSION and that could explain a lot. The FCC might have certified the phone as apporved for sale on the condition that it could not transmit in the FM commercial bands, and that might have meant knocking out all FM TX/RX as one feature set.
If that was true, Moto could have gained a lot of good will by simply saying "We couldn't get FCC approval for the FM radio, we tried."
So few companies get it: You play honest with the customers, they become fans. You play honest with the fans, they respect you. They become loyal to you because you've been loyal to them. And then the sales start going up and everyone becomes happy.
Now that Google owns MotoMobility...Ah Jeez, talk about the deaf leading the blind.

It has totally different internals since its an Intel device. The MSM8960 is what the Razr M has and it does have FM radio, whether or not Motorola wired it up is another question.
From Qualcomm's Website:
The latest family of Snapdragon chipsets will include the single-core MSM8930™, the dual-core MSM8960™ and the quad-core APQ8064™. All chipsets in the family will integrate a quad-combo of connectivity solutions — WiFi, GPS, Bluetooth and FM

Your best bet it to hope the international version of the M or the HD shows up with an FM radio app. Its possible the chip is wired up but no app was loaded. This is how the Droid 3 and Bionic shipped, the app used was from international phones or earlier Motorola phones. But that was easier because they had been on the OMAP platform for a few years. Now that they are using S4 chipsets, you'll need to find something else. You could try SpiritFM but try at your own risk as its quite a powerful app and use on an unsupported device could possibly cause issues.

Spirit only breaks a few speaker on OG Galaxy S's. Nothing else bad has ever been reported.
My findings on these new Motorola's are here: http://forum.xda-developers.com/showpost.php?p=33135362&postcount=4614 and here: http://forum.xda-developers.com/showpost.php?p=33241361&postcount=4635
The quick summary is that an SMD channel is not opened for "APPS_FM". I don't know enough about the mysterious, undocumented SMD channel arrangements on Qualcomm devices to say why, at this time anyway.
You can see the top of my thread for free versions to test: http://forum.xda-developers.com/showthread.php?t=1059296 but it won't tell me anything I don't already know.
Perhaps a custom kernel or ROM will help, or someone will figure out the magic to make it work.
THEN,... we have to figure out if the FM antenna pins are connected. At least the audio is all digital, so I don't think that'd be the normal big problem.
I'm hopeful but past experience makes me think we may discuss this for months, at least, before any resolution for yes or no. Unless maybe we see a variant with FM.

you'll be annoyed to hear that the Aussie Razr M has a perfectly working FM radio.... probably the radio chip we use (GSM/LTE1800) is different to your CDMA one.

Now I'm curious, I'm assuming the Razr M uses the same S4 chip which has FM capability. I wonder if the apk could be transferred to US Razr M's and get FM working. On older Motorola phones there was an FMRadio apk and an FMRadioservice apk. Both were needed to get FM working.
Its still possible that the US M has FM, its just been shipped without an app. This has been the case on other Motorola phones. Unfortunately Verizon would rather have us use up data streaming so they can make more money.

FM radio and GSM/LTE radios are completely distinct.
Where did you get this information ? Nothing I see on Telstra's site or from a quick Google.
If it has the same hardware and PCB, then I'm very happy to hear that, because it means we just need "software". But there's no guarantee there isn't some locked bootloader type obstacle.

If "mere software" could make the FM work, I'm reasonably certain Spirit should work, or at least show more promising signs, and it doesn't, yet.

Thanks for the log from Spirit. RSSI seemed good for a while there. You may get audio if you set Audio-> Method to "HTC OneX QCom" or "HTC OneX ALSA".
First weird thing I see are the FM app and service names under /system/app:
-rw-r--r-- root root 1122913 2012-09-21 19:13 signed_FMRadio.apk
-rw-r--r-- root root 40307 2012-09-21 19:13 signed_FMRadioService.apk
My first fear was that "Signed" meant some sort of "security" measure to prevent it running on other variants of the phone.
But all apps are signed, so I think it was a last minute addition, perhaps due to a customized app load. It's not odexed like other apps either which strengthens that theory.
I've sent you Unlocked as it would be nice to verify RDS.

OK, whats verify RDS?

I just mean see if RDS works. If a station transmits it, you should be able to see song or other info on the Spirit Unlocked screen.
It would only work using a high level OEM proprietary API though, not the low level.
My impression at this point is that the Motorola stock FM app and service alone won't FM enable devices that don't ship with FM enabled. I'd be happy to be wrong though.

Hurrah using HTC One X settings I get radio via your app. Sent you another log. no RDS thou

So, the radio is working? I'm near NYC and this is something that would be extremely useful to me as we have limited access to power and tv/phone/net.

No. I've got the Australian version which has radio natively. Just getting some logs to help

Yep.
And I don't think we know yet if there is some slight hardware difference in the Australian variant, or a difference in boot-loader or kernel or libraries or what.
My feeling at this time is that simply installing the Australian FM radio and FM service APKs won't magically enable FM on other variants. But someone needs to try and I'll be happy to be wrong. But then again, the fact that my FM app Spirit works on the Australian model but not on others, even rooted, is a pretty good sign that my feeling is correct.
And don't expect quick resolution on the various questions about whether it's possible and how, unless there are some lucky breaks or someone with the skills, time and phone shows up. Many similar threads for other phones have gone on for months.

I diffed the xt905 system with the xt907 system and found there are some files referring to fm radio in /system/etc/snd_soc_msm. I tried installing them along with the two /system/app apk files but still nothing. there don't appear to be any /system/lib .so files relating to the fm radio but I installed all of the ones that only the xt905 has anyway, still nothing.

/system/etc/snd_soc_msm is only sound stuff.
It's "vestigial" and won't help.
What you need is a working /dev/radio0 "pseudo-file". You get that by successfully loading the firmware with:
setprop hw.fm.mode normal ; setprop hw.fm.version 0 ; setprop ctl.start fm_dl
I think that does an insmod on radio-iris-transport.ko .

Can anybody actually check for fm radio support?

Using spirit fm perhaps?
I know this has been posted before, but but nobody really bothers paying attention
So, someone with a N4, does spirit fm work at all?

Not sure if the N4 has an FM chip or not.

Thank you
Things aren't looking too good for the Fm crowd sadly

I think Spirit FM's developer wanted people to post an in-app log to him from the N4, to see if he can tell if we'll ever get FM working (because stock FW was never likely to work in the first place)

Both the nexus 4 and US htc one x use the same wireless chip. And the latter has FM radio support, so, I doubt we can't have it too. It might be matter of someone developing a kernel and/or ROM with it.

There was a massive thread on it somewhere here in Q&A, and the developer of spirit even chimed in. Someone compiled a kernel with ask the right drivers, and when everything was said and done, they arrived at the conclusion that FM Radio is crippled on the N4, just as it is on the GN.

Just because it uses the same chip, doesn't mean they can't still disable it at a hardware level
