How to setup STMM32Lo72CZY6TR MCU

I'm trying to set STMM32Lo72CZY6TR MCU along with workshop video on YouTube.

I also install Virtual COM Port and install AT_slave_exe.bin on the kit.

However I received "AT_EROOR" when I input "AT".

This is first trial to use this discovery kit.

I appreciate it if you could give me some advice.

Best regards.

Perhaps you can try over and be specific about what software you got from where, and which video you're referring too.

Thank you very much for your reply.

I checked "LPWAN workshop - 2 AT Slave Hands On" via Youtube.

Now, I use another GW which is ordered by partner.

But, I understand that it is no problem to use another GW when I check "AT command response".

I refer to attached document which is provided by ST Micro.

I really appreciate your cooperation.

Best regards.
