Question
What is the cause to switch from OTAA to ABP automatically in the LoRaWAN software in STM32WLE5 ?
We developed our software in our STM32WLE5 board for LoRaWAN applications. It is working well to connect the TTN with OTAA in the NUCLEO-WL55JC1. When we migrated the software to our board with modification of the RF switch control GPIO pins, the software switches to ABP and sends the data out although it is actually not connected to the TTN server.
Is any expert be able to help in solving this issue ? Many thanks.
Kind regards,
W.K. Tam
