Is it possible to extract the raw data in C of both antenas in different arrays

From in the P2G code you can see, how the data is packed into the transport buffer:
In function send_frame_data(…), in file EndpointRadarBase.c you can see that
• 1st the signals per Antenna are interleaved
• 2nd the Antennas
• 3rd the chirps
are wrapped into the message.

So from the frame format it is would be possible to find the required samples.
Important to know, that the comlib is providing already float values, so no need to care about the 12 bit packing.
