Hello,

thanks for this firmware this helps to understand a little more about espnow
I program the transmitter and receiver on tw esp32 dev
I copy the Mac from receiver into the FW for tranmitter (by the way I add now receiver MAC on Receiver FW in setup such to avoid having to run the GetMac before then flash the receiver FW)
Receiver is rebooting every second obviously no receiving)
Transmitter loop on "Error sending the data"

Any idea about what can be the pb ? I try with 2 other Dev board with same result

SCROLLING SERIAL MONITOR IFOUND OUT THIS :
20:34:28.022 -> Succes: Initialized ESP-NOW
20:34:28.022 -> E (334) ESPNOW: Peer interface is invalid
20:34:28.022 -> Failed to add peer
