SIM7080G AT Commands for MQTT


have anyone an example how to connect to HiveMQ Cloud over AT commands with an SIM7080G chip?

i have tried for hours but, i do not find the right commands…

need i a ca file?
with python on macOS I need no ca file and on iPhone with swift I need also no ca file.

i am using the sim7080g with a raspberry pi pico (micro python).

Thanks :slight_smile:

Hi @joe94 ,

Great to see your interest in MQTT and HiveMQ, welcome to our community!

In general, this is not enough detail, I’m assuming you’re having trouble getting SSL to work.
this usually has one of these two causes:

  1. your device doesn’t contain/support the ISRG X1 root certificate (Where to download)
  2. your device doesn’t support the TLS-SNI (server name indicator) extension, which is necessary to use Free/PAYG HiveMQ Cloud.

I hope this helps,
Dasha from HiveMQ Team
