Is it possible to send AT command from a Nucleo-L0x to a B-L072Z board? (LoRa)

My purpose is to realise a new set up for LoRa.


Before, I used a B-L072Z-LRWAN1 board with the I-CUBE-LRWAN1 software with the End Node code or the AT SLAVE code.


For the AT_SLAVE code, I used a terminal to send AT COMMAND to the MCU of my LoRa module.


Now, I want to configure my B-L072Z board with the AT_SLAVE code (as I realized before) but send AT_COMMAND with a Nucleo_L073RZ board with the AT_MASTER code (and not with a terminal). In comparison with this picture, I don't have application module and my AT_master module will be a the Nucleo_L073RZ board.



Is it possible? Is the AT_MASTER code functionnal with a Murata LoRa module? Should I just connect Tx-> Rx and Rx_>Tx and GND of the two board to communicate (UART) or there is some modification with jumper?


Thanks in advance!
