Thomas Kolb 3b7628882c utils: open output file in binary mode 2023-05-12 13:49:20 +02:00
Thomas Kolb c8e0516e80 Implement time-based carrier sensing 
In the following events, the modem cannot switch to transmit mode for the
given time:

- after a preamble has been received, for 500 ms
- after a packet has been successfully decoded, for 1 ms
- after receive mode was initially enabled, for 500 ms

Note that the times are that long to work around the RX/TX switching of
the hackrf and can be hopefully reduced to <10 milliseconds in a later
version.
