Hello @rishika
Welcome to HiveMQ Community! I did a quick search on the internet and couldn’t find any official documentation on MQTT AT commands for Ai-Thinker A9G board.
Apart from the lack of documentation, I found some examples of MQTT TLS using the SDK they provide, you can start from it.
https://ai-thinker-open.github.io/GPRS_C_SDK_DOC/en/c-sdk/function-api/mqtt.html
Kind regards,
Diego from HiveMQ Team
