A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

AN2606 describes the pins involved. Shows the UART Rx pins. You send an 0x7F data pattern at baud rate with 8E1 format for it to auto baud.

AN3155 describes the protocol after you reset with BOOT0 HIGH.

See examples on Arduino MKR WAN1300 Github
