@onyeka_embedded so this particular error “+CMQTTCONNECT: 0,34” indicates that you have a connection failure using the MQTT protocol. The specific reason for code 34 well depends on the module implementation, but it often relates to issues with TLS/SSL certificate verification most of the times
I don’t know if the endpoint URL in your AT+CMQTTCONNECT command (“tcp://xxxxx:8883”) matches your AWS IoT Core endpoint exactly, including the region identifier. Check AWS IoT Core console to find that end point.
Yeah, copied the end point from AWS
I am looking to build a project in IOT, but choosing a topic became a problem for me so I ask ChatGPT to list topics I could do. I am thinking of building a Remote Monitoring System using three sensors connected to two arduino WiFi microcontrollers and maybe two microcontrollers to connect the actuators, the sensor is connected to the AWS iot core where I will provision DynamoDb, Lambda, kinesis, alert system and a cloud watch, the actuators will receive commands based on mqtt from the AWS cloud and I intend to use IaC to provision the resources. Can someone advise me because this seems too much and I don’t know what I am getting into. Thank you
