AMAZON AWS IOT EXAMPLE
|
||||
|
||||
Description:
|
||||
Connect to Amazon AWS IoT. It requires MQTT protocol over SSL session. The original MQTT library client handler does
|
||||
not support IP port for MQTT over SLL (8883). So we implement it without client handler. You need to undef MQTT_TASK
|
||||
to enable related configuration.
|
||||
|
||||
Configuration:
|
||||
Modify MQTT_BROKER_SERVER, THING_NAME, rootCABuff, certificateBuff, privateKeyBuff based on you account settings.
|
||||
|
||||
Execution:
|
||||
You need to connect to WiFi manually by AT command. After connected the mqtt connection will preceed.
|
||||
