Has anyone had success with installing “external” certificates into the SIM800L?
I’m no guru in this area, and especially not in SSL/certificates, but I’ve tried out to use the internal SSL-certificates (by setting the command AT+CIPSSL=1 before doing CIPSTART), and it seems to work fine.
However, I plan to try out MQTT against Azure IoT Hub, and it seems to require a separate certificate:
The Digicert Baltimore certificate is available here:
I’ve downloaded the .crt-file, and installed it into the Sim800L’s file system as described here in sect 3.10 in this doc:
- but the SSLSETCERT-command fails, most likely because I don’t have a password to put in.
What password is to be used here, and how to obtain it?
I find sparse documentation regarding this; Has anyone had success using external certs for this module?
