Arduino Portenta GNSS MQTT to AWS IoT | Telit Cinterion IoT Developer Community

Hi.
I have searched around for any blog or example how to setup with AWS IoT. I understand I need to install certificates and configure the endpoint on the modem via the AT commands using the serial interface on the H7 but not sure how and what to check if I can't establish a MQTT 8883 connections
Any help would be very much appreciated :)
thanks

Hello,
If you want to use AT interface and embedded MQTT client you have to install certificates on the module as AWS probably requires the client certificate. By default the module also checks the server certificate (you can disable it), so you should install the server certificate.
You should have 2 documents:
- AT commands specification (which also includes some basic examples of MQTT)
- Application Note 62 - Transport Layer Security for Client TCP/IP Services
Please also see these links:
