Re: [cf-dev] Response unknown Token: Rejecting CON-2.03

Looks like the token does not match the one used in the request. Best use Wireshark to confirm this.

Then check your CoAP implementation on the device, why does not mirror the token correctly.

If it does mirror it correctly, maybe something is wrong with your request. Always use the CoapClient to issue request. Only use the raw (advanced) Requests when you know what you are doing (they are not reusable for instance and you need a new instance for every request you issue).

Hi there,

We are using CoAP Califormium library for a server implementation communicating with an IoT device

The server sends a command/query to the device and receives a Valid acknowledgment from the device

 

However we are seeing an error message from the library: Response unknown Token: Rejecting CON-2.03

and would appreciate some “user guide” to interpret/take action of reported errors

 

best regards,

Jamal Mouline
