It requires root (so don't forget to run "su"). Run directly from Terminal Emulator, make a script in GScript or wait for someone to make GUI (XsCode made one - http://android.modac...p...t&p=1421228).
There's one problem - there's no way how to change the radio volume from the Android OS. It will probably require more low level access.
Turn on FM radio
Turn off FM radio
Tune a station
fm_hcitool 3 xxx*xxx = channel 880 to 1080 (88.0 to 108.0 MHz)
Scan all stations
fm_hcitool 10*Results are saved to /data/fmrssi.txt
Change/lower the volume
??I don't know.
