Won't receive msg after sending at least one

[snachmsm]

After sending first message RX gets broken and I'm not receiving/decoding any msg... (only seeing gain in RSSI, so it comes)

First run and I'm receiving msgs without a problem, after sending at least one any msg won't be received. Hard to implement req-resp messaging...

Problem lies in LoRa module, as when I re-flash Arduino without disconnecting RFM (still powered up) then this WON'T fix a problem, still msgs aren't received, even first (when previously sent smth, even before flashing). I have to make hard-reset (power) for bringing back receiving possibility...

fixed with

writeRegister(REG_DIO_MAPPING_1, 0x00);

placed in startReceiving() just before SetLoRaMode(RF96_MODE_RX_CONTINUOUS); call
