Tradfri Pre Shared Key Generation about coapnet

[DubbyMcDubs]

Solved. For anyone looking at doing the same thing, use the following code. The hint in getting it to work came from this line of code in another project (https://github.com/eriklupander/tradfri-go/blob/master/main.go#L170)

To create a PSK:

using (var LCoapClient = new CoapFactory().CreateClient())
{
    var LConnectOptions = new CoapClientConnectOptionsBuilder()
	    .WithHost("INSERT IP ADDRESS HERE")
	    .WithPort(Convert.ToInt32("INSERT PORT HERE")
	    .WithDtlsTransportLayer(o => o.WithPreSharedKey("Client_identity", "INSERT SECURITY CODE ON GATEWAY HERE"))
	    .Build();
    
    LCoapClient.ConnectAsync(LConnectOptions, CancellationToken.None).Wait();
    
    var LRequest = new CoapRequestBuilder()
		    .WithMethod(CoapRequestMethod.Post)
		    .WithPath("15011/9063")
		    .WithPayload("{\"9090\":\"" + "INSERT YOUR CUSTOM CLIENT ID HERE" + "\"}")
		    .Build();
    
    var LResponse = LCoapClient.RequestAsync(LRequest, CancellationToken.None).Result;
   //...use LResponse.Payload to get the new PSK
}
