I’d received the following files from our FAE example_mqtt.c, ril_system.c, ril_urc.c using which we can add MQTT support to M66_OpenCPU_GS3_SDK_V2.4_Eclipse. I want to use it to connect to Google IoT Cloud.
I have 2 questions:
- Whether quectel mqtt uses SSL.
- How do I provide the private_key.pem in order to make secure connection.
