Adding CoAP to the actuator is done in more or less the same way as the sensor. The main difference between the two is that the resources will be used for the control resource instead of data readout. For this reason, the POST
method will be used instead of GET
to send data to the actuator. We start by adding a CoAP endpoint to our actuator, as follows:
CoapEndpoint CoapEndpoint = new CoapEndpoint (); Log.Information ("CoAP endpoint receiving requests on port " + CoapEndpoint.Port.ToString ());
First, we define a series of simple control resources named do
N
/txt
that can be used to read the state of the digital output, as well as change their status using simple plain text GET
and POST
method calls. In the resource name, N is used to identify which digital output is being referred to. When we register the resource, we need to provide two delegates. The first delegate will handle the GET
method call and the second delegate will handle...
