I need some help. I'm trying to connect my Portenta H7 to AWS using the Portenta CAT M1 NB-IoT module with MQTT and AT commands.
I found that the AT^SBNW command should work for this, but I haven't been able to find examples, so I'm unsure how the command works.
I believe the first step is:
AT^SBNW=is_cert,1
However, I'm not sure how to proceed with creating the secure command with certificates after that.
Can anyone provide guidance or examples?
