I am using rfd900 radio for communication between my drone and system, Firstly on both sides I used rfd900 and was able to get the data correctly on the system. I was manually serializing and sending the data from transmitter side and reading it on Putty on the receiver side. Now I am using plutoSDR on the receiver side and to get the IQ data. I am running a MATLAB code that generates a CSV file which then I give input to URH and generate a binary data file, Now I am checking the binary file manually to verify Whether I am getting the data correctly, So yes there were Sik frames present in the binary file and was able to extract preamble, sync1, sync2, netID, length fields correctly but the payload of it contains different data then MAVLink. but the Sik payload contains an MAVLink packet. Does anyone have any idea of it? I am sharing a sample packet below that I extracted from the binary file
[0101010101010101010101, 2d, d4, ff f8, 10, 9a 10 8c 33 25 e4 7d d0 24 70 97 6f 08 5a c7 83, ff, ff ff]
[preamble(22 bits), Sync1(1 byte), Sync2(1 byte), NetID(2 bytes), Payload_length(1 byte), Payload, Trailer(1byte), CRC(2 Bytes)].
