SparkFun LoRa Thing Plus expLoRaBLE not working

Sunday, 2021-03-07

After disruption in household wireless connections but without any other changes to files, code, connections or board, this morning I get this error:

C:\Users\clsnf\OneDrive\Documents\Arduino\libraries\BasicMAC\src\lmic\radio-sx126x.c:778: assertion failed.

Error derives from this line in radio-sx126x.c:

ASSERT( ReadReg(REG_LORASYNCWORDLSB) == 0x24 );

Why the change?
