nRF905 single-chip radio transceiver demodulator + FLARM protocol decoder
I am not able to setup a connection between flare an QGroundControl (Ground Control Station). Which port should I use for that connection ?
Hi, Since April 1st the received data seems not correctly decrypted. I think you are already aware of this, do you know of any effort to reverse engineer the new...

Because the nrf905_decode binary uses `gettime` internally, its output does not reproduce. I'm not sure what the best way is. Preferably, rtl_sdr would write out a format with timestamps inside,...
Max ADC value 255 - 127 is 128 unsigned, which is actually -128 in a signed int_8. // sliding_dft(raw_buffer[i] - 127, raw_buffer[i + 1] - 127); sliding_dft(raw_buffer[i] ^ 0x80, raw_buffer[i...
