Hi,
It seems that there was a previous inquiry by another poster in the international forums, but I felt that this question would be better posted here.
Would anyone happen to know if the i747 has hardware support for FM radio? If so, what app would be required to get it up and running?
Thanks in advance.
I think the current state is that there is hardware support in the Snapdragon SOC, but it's baked into the bluetooth module. Unlike the HTC One X (which uses the same SOC), Samsung chose to put in a Broadcom chip that controls WiFi and Bluetooth, disabling that functionality on the Snapdragon. Given that Linux can only support one bluetooth module at a time, the module on the SOC cannot be enabled. Last I checked people were looking for a solution. I'm not sure if that's still the case.
So with that being said what is needed to tap into the FM radio even if it is combined on. Chip with bt and wifi?

According to here: http://www.ubmtechinsights.com/google-nexus-7-teardown/ there is an
AzureWave AW-NH665 chip which is endowed with an FM radio tuner. It would be really awesome if some talented soul could develop an app for that!

It depends on whether or not the bcm4330 chip actually sends power to that module. I haven't seen that module fire up in dmesg. That could mean that we simply need a driver for it. The fm framework is already out there. I'm not really a hardware guy but just some thoughts.

On another note, I have been playing with Samsung & HTC modules & drivers for the 4330 (Vivid & Captivate Glide) & I am getting 5Ghz wireless-n working sporadically. Just as HTC has added the capability to newer roms, it would also be possible for it to be supported quite easily by Asus as well. Would be great for streaming.
I would love to see this as I'm sure many would who wish to use the FM Radio for and N7 in a car install, I would gladly pay into double figures for this feature, any devs wishing to take it up there is a big market for getting fm radio working on the n7, do it and watch the £££ fly in ........
I doubt if a driver without an antenna would work - and I saw no sign of an FM antenna in the teardown.
5GHz support would be sweet... Antique adapters in the house really keep me speed limited on 2.4GHz (54MBS)..
That really sucks about the antenna. sometimes I like to listen to the football games out in the yard. Guess I'll have to use my phone.

I think perhaps the most definitive answer to this would be from Mike Reed, who I believe has a Nexus 7 and is also the author of the Spirit FM app. In this post it looks like he thinks it'll never happen.
Too bad... I use the FM Tuner in my phone all the time as well.
I just use Tunein Radio Pro. Was a FAOTD on Amazon. Used the free version before that. Gets the local stations I like...

Thanks for that info. again, very disappointing.

I use tunin sometimes too, but tunin radio is NOT a replacement for FM radio.

Are you serious? No data use. Good for emergency situations. Easier on battery. List goes on... Always wonder why people don't want fm

Exactly. We got a hurricane bearing down on us right now. The last time this happened, We were without power for 3 weeks, and 3g was a laughable dream because all the cell towers were down. We NEED FM radio.

Your Nexus battery isn't going to last 3 days. If this is for disaster situations, just get a regular FM radio or one of the ones where you can power it with a hand crank. Either way we don't NEED to have FM on the N7. It would just be a nice perk.

Most mobile devices utilize a headset as the antenna. I wonder if this could be as simple as porting a FM tuner app from a device that has the same chip set with working FM tuner app?

I was wondering if anyone had any success? I was thinking about integrating a Nexus 7 as a car stereo replacement. Mount it in the dash (trimmed to make my GM Double DIN space a little wider), and route a line out into an EQ, which then would feed into a couple amps. ~$50 for a used 7-11 band EQ, ~$200 for the Nexus = a pretty kick butt deck if you don't need CD. But I would still like FM for traffic, news, games, radio contests, etc....
Last time I checked there need not be an internal FM antenna, most devices with tuners in them actually use the ground lead of your headphones. This is also why radio apps often fail without headphones or powered speakers attached.

Lol, are you serious? I don't know about you but I had my N7 under clocked at 900mHz with WiFi on, bluetooth off, and display all the way down, and I got a week on my battery. A Nexus 7 is a tank when it comes to battery you could EASILY get 3 days off a N7 battery.
You can have FM on your Nexus 7 now
Just get one of those cheapy RTL2832U based USB DVB-T dongles (they can be as low as £5.60 from eBay - http://www.ebay.co.uk/sch/i.html?LH_BIN=1&_fcid=3&_sacat=0&_from=R40&_clu=2&_nkw=RTL2832U&_sop=2)
Then download SDR Touch - https://play.google.com/store/apps/details?id=marto.androsdr
You don't even need to root your Nexus 7.
You might want to have a powered USB OTG cable in order to make it last for longer, since the tuner and the SDR decoding on the CPU is quite a battery eater. Another downside is that you can't charge your tablet while having something plugged in the USB port.
FM Stereo and even possibly RDS are features that will appear in SDR Touch soon enough
An added bonus is that you can now also listen to police frequencies or analogue TV sound while you drive as well

Tried that, not working, maybe because i do not have powered usb hub. But does anyone know what is the problem when device freezes and restarts whan plugging out otg?
Go for spirit radio on google play.....
Can anybody please tell me how can I use spirit FM on my galaxy s? Is it safe enough? I've heard that it may cause speaker damage. Is it true? Is there any other app available for galaxy s to use fm radio?

There is no other FM Radio. Spirit FM caused (or still causes) speaker damage to 3-4% of the Galaxy S users so there's only a slight chance of that happening. The speaker can be damaged even if you only use it with headphones. If you have used Spirit FM for more than 5 minutes and everything is still good, your phone is not in any danger and you can continue to use it for as long as you like. I use it every single day for 2-3 hours (the trip to work and when shopping) since last year and my speaker is just fine. I have the unlocked version and the developer works on a safer method for Galaxy S and releases the improved one with every new version.
Can you please give me the link from where you downloaded the app? Or I will be gratefully to you if you give me the app you are currently using by any means. Thanks in advance.

Let's start from the top. I am from Romania and in my country many drivers, especialy truck drivers use emision reception stations to speack with one another to inform themselves about police filters and radars. Auto stations use very low frequencies like 15-30 mhz from what i know, i am interested if in any way a phone can intercept those frequencies, maybe emit on them. The radio chip instaled on the phone can hadle these low frequencies, and if so there is any app or someone can develop a app to do that ?
I have no knoledge about radio chips on phones and what they can do
I hope there is someone here that knows that.
(I hope you undestand what i am trying to say, my english is not very good)

Are these stations FM? AM? MW?
The HOX could, in THEORY, receive (NOT transmit) any FM radio transmission provided it falls within the frequency range the hardware is capable of receiving (i'm not sure of the exact range).
If it is transmitted using ANY other system than FM...no you cannot receive them.
Fm

Can u find the frequencies range ? Is there a way to find it ?
I know the standard range is 89-108 , i want to know if i can push the HOX to go lower than that, 27.255 is the exact frequencie i need. I don't know if the hardware alows me to do that.

Possibly No, Because as you know, headset cable acts as the antenna for FM radio.
Some says, Spirit FM works without headset, sorry i never use it.
Also there are mods for Sony, but not found any mods for Sammy. Anyways digging up a lil in the forums may find you a solution.
Playing without headset may reduce antenna gain to a very lower value, resulting poor reception.
