Instructing ChatGPT to produce TLS code on the ESP32

Now, let us list the necessary information in the ESP32’s main code to access AWS IoT Core:

• TLS certificates, which will be stored in the SecureCredentials.h header file
• MQTT server address and port, which will be stored in the Platformio.ini file, for example, AWS_IOT_MQTT_SERVER=\"xxxxxxxxxxxxxx.iot.your_aws_region.amazonaws.com\", AWS_IOT_MQTT_PORT=8883
• deviceID, which will be populated from the HardwareInfo.h header file

Be aware that AWS_IOT_MQTT_SERVER is the endpoint address as shown in the following figure; it is in the settings under AWS IoT. Please remember to remove -ats from the endpoint address because we use the endpoint type of iot:Data, not iot:Data-ATS.

You can now continue using the code created in the previous chapter and add the TLS MQTT requirement as the following prompt:
