Hi Andreas,
Is my line of interest irrelevant to the OsmocomBB project? In short,
is the project  intending to explore use of the phone for anything
besides the conventional calling and conventional SMS. If you recall,
my interest was to write code to enable the phone to 'sense' and
detect signal from a remote source of few metres. I need to be able to
write the code. Can i?
I need a response desperately so that i stop cluttering the forum.
