Yes the previous shell script didn't solve the problem... sorry. This might mean that the UDI should contain the interface name as you were saying
The C code misses the setrfkill section, and a !=null check when you fopen the file.

ok here is a new version.
it implements setrfkill too and uses g_strdup_printf instead of sprintf.
