I-NUCLEO-LRWAN1 - AT command issue

[HDesa.1]

Hello,

I am using I-NUCLEO-LRWAN1 development kit for LoRa setup. I have interfaced that setup with USB module and I am trying to communicate it using X-CTU. When I start the module the module sends #, but it's not responding to AT<CR>. I have attached the image of terminal output.

What would be the reason for this?
