PTT (Push To Talk) script example.
|
|
|
|
Assumes Rx and Tx are contiguous device sets with Rx at index i and Tx at index i+1
|
|
|
|
When going from Rx to Tx (push) the device set index specified must be the Rx one
|
|
When going from Tx to Rx (release) the device set index specified must be the Tx one
|
|
Defaults are Rx at index 0 and Tx at index 1
|
|
|
|
Default web API base address is http://127.0.0.1:8091/sdrangel (default of sdrangel web API)
|
|
You may change the address and port portion with the -a parameter. Ex: -a 44.168.40.128:8888
