ESP8266 AT MQTT SSL Certificates not working
Posted: Thu Jun 08, 2023 7:35 pm
I've asked the same question on stackoverflow: https://stackoverflow.com/questions/764 ... 1_76433285
I'm using the ESP8266 (WROOM-02D) for MQTT over WIFI. I'm using AT commands for MQTT. I'm currently using ESP8266-IDF-AT_V2.2.1.0 firmware on the WROOM-02D. My broker has been configured to use both client and server certificates for authentication.
I flashed my certifactes to the module at the following addresses as per the partition table:
I configure the module with the following AT commands:
THE PROBLEM
Whenever I execute the command, the module will reset. The module will reset even if use the default provided certicates. I found that the module will reset whenever MQTT scheme uses TLS (with or without certificates).
When I set the scheme to 0 (TCP and no TLS), there is no issue.
I've tried several things and even different firmwares but cannot get it to work.
When looking at the AT command manual, the MQTT user configuration has a "path" parameter.
I'm not sure if this could be the problem, but I cannot find any documentation on specifying the path.
