CoAP

This page describes the CoAP connectivity in more detail

If a device communicates over CoAP with akenza, a CoAP device connector has to be set up and assigned to a Data Flow.
After creation, a secret is generated which has to be provided in the request. Both the secret and the device ID are set as query params in the CoAP request.
NOTE: The akenza CoAP connector currently only supports JSON content format. Make sure to provide the appropriate header for it.
