FM Transmitter Yet?

Ive seen many threads with questions like these but none of them have answered the question:
Is it possible and will it be done in the future?
Thanks

Ummm, no. The phone does not have a transmitter in it. Just an fm receiver, which doesnt transmit.

it is technically able to transmit but it would need to have that software written for it, the likes of which its taking to get 4g on cm

It needs power going to the antenna in order to transmit, as far as I know it was not designed to do that.

Umm, no. Again, there is no TRANSMITTER in the phone. If there was one, I'm sure sprint would have used it, and touted it as a feature.

the FM chip manufacturer spec sheet lists it as capable of transmitter but htc did not include the firmware for it to work, they also did not include an antenna for it to work (requiring a cable plugged in to receive signal as well) this was discussed months ago in detail, if you search deep in q/a or dev you can find it
found this one http://forum.xda-developers.com/showthread.php?t=693253 it has links to some others

Well, this is turning out just like the other threads, some say yes, some say no.
Is there a developer that thinks that an FM Transmitter is possible?

some of the same chips for BT WIFI are being used as in the ipod touch and those are capable of transmiting as well as receiving so in theory it should work on the evo....then again SOFTWARE

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.

One V Bluetooth Problem

I recently bought this phone and found that there are problems with Bluetooth, I've tried to transfer files to other HTC One V, and its not working, even after getting devices paired, files are not transferring.
I am looking for any patch to solve this problem.

Hey even I've faced this problem and was really frustrated! But for me the Bluetooth transfer worked flawlessly after i switched my WiFi off. Guess its probably due to the Bluetooth - WiFi interference. Hope they fix it soon.

Tried.. Still Not working

Guys this is happening because of bluetooth version 4.0. Most of the devices are not compatible with this one. You will have to download a bluetooth manager app from Google Play shop to resolve this.

I'm pretty sure HTC and the chip company took it into account. Now it's possible they made some errors and a software update might fix it.
Can anyone tell me the manufacturer of the WiFi/Bluetooth chip and if it does FM too ?
EDIT: A ROM indicates Broadcom BCM4330 in /system/etc/firmware. This is one of a new generation of Broadcom combination chips that I've seen to be sensitive enough to even decode RDS with no earphone plugged in as an antenna.
The One X and One S are using a Qualcomm chip, which is a big departure from the TI and Broadcom chips HTC used in the past.
If someone could send a log from my app there's info about that here: http://forum.xda-developers.com/showpost.php?p=26102918&postcount=3
Thanks !

The H1S has a Qualcomm BT chip, the H1X has a BT chip from TI.
Looks like the H1V is on the older and you would hope more reliable Broadcom chipset, the 4330 is used in many other AOSP phones.

That's interesting...
So the H1S is the only HTC device with the Qualcomm chip then... ?
But then why does the teardown for the One X say it has that Qualcomm chip ? : http://www.techrepublic.com/photos/cracking-open-the-htc-one-x/6363151?seq=54
There's an AT&T variant that has a hidden FM app, but I'm not sure it's the same chip as the International H1X with NVidia Tegra.

The Qualcomm chip is the baseband/modem for the phone, not the Bluetooth/Wifi module.

A phone can have more than one Qualcomm chip.
Qualcomm is a chip manufacturer, and they make SOCs, as well as BT/WiFi/FM chips.
They've also acquired other companies, such as Atheros, adding to their chips portfolio.
This One X teardown: http://www.techrepublic.com/photos/cracking-open-the-htc-one-x/6363151?seq=54
Says this: "Qualcomm WCN3660 dual-band Wi-Fi, Bluetooth and FM radio combo chip (WCN3660 PFN634G6 A201002)"

Here is something intresting, I read an article on wikipedia about bluetooth 4.0 and got to know that its actually a downgrade in terms of its functioning. Bluetooth 4.0 is also called as Bluetooth low energy, designed to consume less power from battery, and some of the major features are-
(A) Its speed is less than classical bluetooth.
(B) Its latency is less.
(C) Its range is greater.
(D) It is not voice capable (which means BT headset won't work)
Check out the whole comparision table and more info at http://en.wikipedia.org/wiki/Bluetooth_low_energy

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.

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.

I cancel any order at any time on request. And have been doing so for over 2 years. Back then HTC Desire and Nexus One were big and I still support those (as best I can of course).
Now, GS3, HTC One and Xperia's are big and I'm now supporting those too.
It's a "crazy" job trying to support all these, on MANY different custom & stock ROMs, and nobody else is crazy enough to seriously try it seems.

I presume we were emailing about this ?
My ability to support a device is directly related to how much support I get from customers. If it's enough, I buy the phone to support it better.
I was dismayed all variants of the "normal" GS4 had no FM. I expected to buy one, but got an HTC One instead.
I'd be happy to get some GS4 variant with FM, again, if there's sufficient interest in supporting me. I'm working 70 hour weeks and making about the legal minimum wage here for those hours; That's nice, but don't imagine I'm living in app dev luxury or some such.

I think we can blame the US market for the lack of recording in most FM apps. I think there's some group or something that charges $10 or so for "FM recorders". And as always, US market effects often hit the rest of the world.
I think this is why there are virtually no MP3/FM players that record. It's a simple feature addition is many cases, so it's omission seems strange.
And only one company, Samsung, has (had) recording in their FM app on International high end phones (GS2, GS3, Note, Note2). And none of the US carriers sell/sold these International phones.
I presume that whatever groups demand ransom for FM recording have either never heard of my app, or figure I'm small potatoes and not worth pursuing.

Could be a bug in the kernel FM driver.

Hi,
so I have tried turned off the RDS and it doesn't help.
I live in the Czech Republic and I found several stations with this problem.
The first was Country radio 89.5 MHz (Prague)
My phone is i9195 with Cyanogenmod 10.1 (problem is same on all modifications based on the same kernel) so problem is probably there.
