3 years ago If you look at issue 12 I wrote a test for this reproduced below -
import 'dart:async';
import 'package:coap/coap.dart';
import 'config/coap_config.dart';
FutureOr main() async {
// Create a configuration class. Logging levels can be specified in the
// configuration file.
final conf = CoapConfig();
// Build the request uri, note that the request paths/query parameters can be changed
// on the request anytime after this initial setup.
const host = 'wsncoap.org';
final uri = Uri(scheme: 'coap', host: host, port: conf.defaultPort);
// Create the client.
// The method we are using creates its own request so we do not
// need to supply one.
// The current request is always available from the client.
final client = CoapClient(uri, conf);
// Adjust the response timeout if needed, defaults to 32767 milliseconds
//client.timeout = 10000;
// Create the request for the get request
final request = CoapRequest.newGet();
request.addUriPath('obs');
// Mark the request as observable
request.markObserve();
// Getting responses form the observable resource
request.responses.listen((CoapResponse response) {
print('EXAMPLE - payload: ${response.payloadString}');
});
client.request = request;
print('EXAMPLE - Sending get observable request to '
'$host, waiting for responses ....');
await client.get();
}This still works for me in version 2.0.1. Please run this test to verify operation then re try what you are doing but post a full log, I need to see all the messages exchanged, not just a fragment.

Hello @shamblett , I am using coap version 2.0.1 and checking markObserve() functionality for get request. But it gives following error. Please guide me.
