hi..
i am trying to embed a fixed sequence which i want to recover during
demodulation. I have read from the previous archives that it would be easier to
embed it in the payload part.However, as soon as i add anything in the payload
part, and try to receive using rx_voice, i get an error saying
terminate called after throwing an instance of 'std::runtime_error'
what(): msg length is not a multiple of d_itemsize
Aborted (core dumped)
What I have understood is that the msg length changes as soon as I add
something to the payload.If I dont do anything and just run rx_voice.py then
the msg length comes to be 1687/1720
I have tried getting the msg length after adding different sequences.
If i change the code as:
payload = payload + preamble, the msg length changes to 1719
Otherwise, If i change as:
payload = payload + default_access_code
the msg length changes to 1751
where default_access_code and preamble are given in packet_utils.py.
I have not been able to find out the value of d_itemsize or what should be its
value so that the code runs.
I would be very grateful for any help.
Thanking you,
Pratik Hetamsaria
