P-NUCLEO-LRWAN3 End node AT command terminal communication

I just flashed the end node of the P nucleo LRWAN 3 with the AT master firmware, but I am still unable to send AT commands via my terminal to reconfigure some parameters of the end node. I also made sure I set up all the necessary parameters in the terraterm software correctly and I am still not able to communicate with the end node via terminal using AT commands.

IIRC, 'AT Master' is the one where the STM32 is sending the AT commands to an external LoRa slave device.

So the AT commands are not for you to control the system ?

 

again, the P-NUCLEO-LRWAN3 is marked as NRND - and probably should be marked Obsolete.

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.
