Board: RAK11721 (Apollo3 Blue + SX1262)- BSP : rak_rui apollo3 v4.2.3
Problem: registerPRecvCallback never fires on receive. TX works perfectly +EVT:TXP2P DONEconfirmed every time. Two boards tested, multiple firmware versions, parameters verified identical viaAT+P2P=?andAT+SYNCWORD=? on both sides.precv(65533) returns OK. [ALIVE] heartbeat prints every 10s confirming loop() is running. No packet ever received.
Has anyone successfully used registerPRecvCallback for P2P receive on RAK11721 specifically? Is there a known issue with Apollo3 and the RUI3 P2P receive event? Is there a workaround?
