Hi there,
So it depends on the RATE for the FEC , the 2 bytes are included,
P2P Mode Frame Format
Yes, LoRa P2P (test mode) as used in modules like the Wio-E5 typically operates using:
- Implicit header mode when maximum payloads are transmitted (253 bytes)
- No encryption unless added in software (i.e., raw payload)
- LoRa CRC: a 2-byte CRC is usually present when enabled
- Forward Error Correction (FEC): LoRa always includes FEC, determined by the Coding Rate (CR) setting (e.g., 4/5, 4/6, etc.)
