Re: Information about linux drivers for voice in neofreerunner........
I haven't got any clue about software access of FR's MCU's sound port i.e, IIS port. Please provide me with help regarding this. Thanks!

Hi, I don't know the laws of your country, however, encrypting GSM might be illegal.

Re: Information about linux drivers for voice in neofreerunner........
Hi Arslan, A while ago i tried to write a software modem to communicate between 2 freerunners. One of the things that went wrong was a 90 degree phase shift in the audio signal. So when you write audio software, please keep in mind that it might get phase shiffted.
