FM-Transmitter

Hello,
Is there anyone that now if there is a program to X1 or any mobile that makes the mobile phone to an FM-transmitter?
Since there alot of technology like GPS, RDS cant that be done? Im very bad at this stuff and is very impressed by the programming persons that makes this stuff possible!!!!
Best regards John

i think its not possible cause it needs other hardware in the phone

Bluetooth is technically a form of FM radio, but I think you'd need some very advanced custom firmware to transmit analogue FM. In fact, some Bluettoth chips are also FM receivers. It's very low powered too, so you'd only get a few metres range from a transmitter. The chances of it being implemented seem very small.
But if you just want to transmit to your stereo, there are plenty of mini-jack to FM radio transmitters. They work best if there is line of sight between the transmitter and receiver.

... the Glofiish V900 has this function

the x1 doesnt have it, and i dont think it will. You can however search for an FM transmitter that will fit in the 3.5mm jack. these are sold in a lot of places and searching google yielded a lot of results. this is probably your best bet.

good day =)

transmitter == send
receiver == receive
transceiver == send and receiver
fm radios only have receivers
wifi/bluetooth are transceivers but only on 2.4Ghz Digtal signals using a spc. and only that protocol (it's how the hardware is made)
fm is from about from about 87.5 to 108.0 MHz analog
but this product
http://catalog.belkin.com/IWCatProductPage.process?Product_Id=166893
will transmit any audio from any device which can send analog audio
to a 3.5mm minijack
to the fm band one set it to
i have one it works ok not HD audio quality of cause but works

Do headphones increase data reception like the FM radio?

So noticed it won't let you use the included FM radio without headphones plugged in as they act as an aerial. Was wondering from people who use headphones more often, do you find it improves data rrcrption az well?

No, completely unconnected aerial. The data/phone aerial(s) are inside, there is no FM aerial, the wire of the phones becomes the aerial.

Adding to that - not all headphones will just work as FM aerial. You will need to use the default HTC headset as far as I know to get a signal.

FM Radio & Bluetooth

I have cause to use the FM radio but listen with a bluetooth A2DP headset. The bluetooth headset says it is connected for media and phone audio. However, the FM radio audio does not get redirected. How do I enable this? Is there an alternate FM radio app that will direct the sound to the bluetooth headset?
And before you guys jump on it, yes in fact there is a cable attached to the headphone jack for antenna. I just don't want to have to use a wired headphone to listen.
little background:
I like to listen to a particular radio station while I ride my bike. I also like to use my phone's GPS feature with a bicycle computer app while it is mounted to the stem on the bike. So it is terribly inconvenient to have a cable running from my ears to the phone while it is mounted on the bike. I built an antenna cable for the phone that connects to the stem cap bolt on the bike, using the bike's steel fork as an antenna. It works brilliantly with the phone's FM radio set to "Speaker", but when you set it to "headset", it doesn't redirect the sound to the bluetooth headset.

It seems too me that the phone is thinking (yes, thinking lol) that it has a headset plugged in and is trying too out put the audio via the headphone port... I kind of know how you feel because wires while riding a bike is quite cumbersome. It clearly seems like an overlooked problem, but most definitely can be fixed via software. I've been looking at bluetooth headsets for a while now, and this seems relavant to my interests... Good luck...

[Q] Bluetooth AM/FM App?

This will probably sound a bit dumb, but here goes... Since Bluetooth utilizes FM frequencies, is it possible with the correct app to use your Bluetooth system as an FM tuner? Basically, is there or is it possible to create a program that enable a user to pick up FM radio station broadcasts with his Bluetooth reciever, and listen to them? In that same vein, is it possible to use the built-in Bluetooth as an FM transmitter, to transmit audio streams at frequencies that can then be picked up by a car radio, or boombox? this would eliminate the need to purchase an unreliable FM dongle, or adapter cable if you wanted to hear your device's music on your car stereo.

where did you hear that it utilizes fm frequencies? bluetooth operates at 2.4ghz like wi-fi (but different protocols).... when someone says that a device has a bluetooth/cellular/wi-fi radio, they dont mean it has anything to do with am or fm unless specifically said (ie; am-fm radio).. but, why would you even bother asking that question anyway? if such a thing was even remotely possible you would surely have heard about it and seen products for it all over the place, hell, a simple search on ebay would turn up thousands of devices if they existed...

Even if it were FM, the BT receiver would still require a tuner chip to bring in the different frequencies.

Looking for a smartwatch that works as music player (via bluetooth)

Hello to everybody,
I'm looking for a smartwatch that could be paired with a couple of bluetooth earphones, acting as music player and that could works without a phone.
I found a lot of cheap device that has a TF (microsd) slot and that could be paired with bluetooth earphones, and this is good.
But I would like to have also Radio FM and I was unable to find a device that could work with bluetooth earphones because all the devices I found with radio FM needs to have earphones jack inserted because they act as antenna.
So I started looking for a device that could run app without a phone, something like "tune in radio", that streams music via data connection, but I'm not sure if someone has already developed something similar, I've seen that Samsung has created the Gear S that has a 3G and wifi connection but I'm not sure of what are its capabilities, if it could work alone (without a phone) for the task I need.
Does anybody knows if there's something that could fit my needs? (or mp3 stand alone with radio FM via bluetooth or mp3 with undependent streaming radio app)

If I could throw a bone...
I carry an iPod Nano 6G. Relatively cheap, doesn't have Bluetooth, but it has been my goto for music. I paid $10 for a stainless steel band, it has a week battery life typically, and its just a good device overall. If you're willing to compromise Bluetooth, it can't break the bank.

Thank you, but I can't give up bluetooth, Nano was one of my first choice but it doesn't fit some of my requirements.
Probably some other little device like this small phone could be good. Does anybody knows it?

Basically any MTK6260 based smartwatch will do.
I listen to music at work straight from my GT08. Either via bt heaphones or via the sound system since it has a bluetooth receiver.

Yes but it also works with fm radio ?
All the reseller I contacted told me that in order to listen fm radio I have to plug earphones into the 3.5mm hole because earphones works as antenna.
Did you try to do it without

well, best I can think of is an actual headphone with built-in FM radio, kind of like the Sony MW1 - or if you prefer, there's sport-headphones with all kinds of options (SD card, FM radio, etc.) which don't require any kind of additional device/bluetooth/etc. and are pretty much just headphones with a wire between the two. Example: Sport Wireless+ by Jabra has FM radio.
problem is, that for FM radio you will always require SOME kind of antenna - if I remember correctly it has something to do with the wavelength of FM and needing a certain minimum antenna length to pick up the signal. In cases with no cable (e.g. big headphones (over-ear)), the antenna is built into the frame, while in-ear headphones require some kind of cable/wire (even if it's the one connecting the two headphones) to function as antenna.

I agree with you but I just received a pair of Plantronics beatfit bluetooth earphones, that are superbs in terms of quality, but that lack the embedded radio FM as Jabra ones!
About the antenna, it's strange, because I think that if it's possible to integrate it inside a couple of bluetooth earphones it should be possible to do the same also in an mp3 player or in a smartwatch, don't you think?

Problem is basically that the shorter the antenna (compared to the actual wavelength) the worse the signal (more or less, google "FM antenna length" - or anything similar - for the specifics involved). And considering that FM has MUCH larger wavelength than any other frequency used in a phone (iirc BT is more or less 12cm, FM is 3m), having an antenna small enough to fit in a watch or phone COULD work, but the signal would be really bad - so you'd have to make the receiver REALLY sensitive and probably use quite a bit of power.
Kinda like the difference between turning on a world clock radio with & without extending the antenna - it'll "work" with the antenna collapsed (and maybe even pick up a station or two if you're lucky), but it'll work much better with the antenna extended.
FYI: The larger the wavelength (and thus lower the frequency), the further the signal travels & less interference from objects in between - reason why in the middle of nowhere between trees and mountains you'll pick up an AM (approx. 1kHz, 100+m wavelength) signal much better than an FM signal (approx. 98kHz, 3m wavelength). Same reason as to why the lower mobile bands (700-800) are more suited for large area coverage than teh higher frequency ones (2100, etc.).
NOTE: You'll have to forgive me for any (probable) errors in specific numbers - it's been a LOT of years since I last used/checked them

addendum...
Ok, apparently a full-length set of headphones (to some extent) isn't even needed nowadays - basically phone makers being lazy. Check this thread over @ androidcentral.com about someone getting the radio (not through BT though) working by sticking a cut-off 3.5mm jack stub (of an old pair of headphones).
No test on how WELL it receives various stations, but at least something is picked up... now all you need to do is modify the ROM so it'll allow BT broadcast even with a 3.5mm jack plugged in :silly:
Or maybe (as suggested in the thread), plugging in a standalone BT transmitter into teh 3.5mm jack?
