Guideline for testing IoT device

Our company is testing a few IoT solutions and we are interested in setting up a connectivity test with InfluxData and then displaying data on a dashboard solution such as Grafana. We have already performed two connectivity tests with our IoT device: 1) sending data to AWS via MQTT commands, and 2) using PUT commands to send data to another IoT database solution provider.

We are looking on the InfluxData site any documentation which will guide us in testing one or both of the two methods – MQTT and/or PUT.

Any direction from the community is greatly appreciated!
