Hello! I’m communicating 2 RAK3172 using P2P.
Is there a documention where it describes how is the P2P frame constructed? Does it have a header and a CRC? I couldn’t find this anywhere.

Thanks in advance.

Hi. Thanks for answering, but my real question would be:
Is RAK3172 P2P actually using those Header/Header CRC/CRC? The documentation says that those are optional fields.

If the chip uses CRC, what happend when the CRC control fails? Does it output an +EVT?
