Hello Javispedro!
That are good news!
Can you please tell me with which software you do this?
Or can you give a little piece of code?
With the regular programs you have to choose:
plug the headphones(antenna) or not.
If you plug the hp the transmitter doesn't work.
If you don't the receiver doesn't work.
I only want to send a sample (e.g. sinus curve) of 1 kilobyte with a fixed sampling frequency with the transmitter at a fixed radio fequency.
And I want to get the result at a fixed sampling frequency at the receiver with a fixed radio frequency.

Depending on whether you want to have the HP cable plugged in or not you should do one or the another.
I always wanted to file a feature request in fmradio to make the above a gconf option but I tend to forget

Follow the guide on forum for removing the frequency limit of the FM Transmitter, it has the added side effect of allowing FMTX when radio is active. Need to enable FMTX before plugging headphnes or runningFM Radio.
There are people that pretend that it is not possible to use the receiver and the emitter at the same time.
Is that true?
Is that a hardware limitation?
Or is that a kernel limitation?
Or is that a userland limitation?
I can't imagine that this is a hardware limitation, because both (emitter and receiver) are on a different chip.
The only hardware limitation could be the antenna part.
But as I'm experimenting with communication inside the device I don't need an external antenna any way. And the FM-chips have their own internal antenna on the chip.
So: What's the reason, why communication between the FM-Chips should be impossible?
