Planning on sending MQTT messages to Amazon AWS via the HL7800 module. Do any support documents exist that talk about this ability? I have seen a couple people say they have succeeded, however, I was wondering if Sierra Wireless is acknowledging support and providing support material?
Hi @tremmert, are you talking about the OTA to the third party server? I think you can refer to AT command guide section 10.7. +WDSTPF Command: Device Services Third Party FOTA.
Please refer this document to add device on AWS cloud https://docs.aws.amazon.com/iot/latest/developerguide/register-device.html
-> You should create Root CA cert, client cert and key and then add these certs/key to your device.
This server requires client certification authentication, so you should configure authentication mode =3 with ksslcrypto command
And then, using secured TCP connection to send MQTT packet, ex: at+ktcpcfg=1,3,“xxx.iot.xxx.amazonaws.com”,8883
Please refer this document for MQTT connection on HL series https://source.sierrawireless.com/airvantage/avc/howto/hardware/samples/hl-stnucleo-mqtt-c/
