I change
//final buff = Uint32List.view(valueBytes.buffer); final buff = Uint16List.view(valueBytes.buffer); to solve it, but I ran into another problem: I get response when the resource's state not changes, is it right？ Please guide.

I can't see this line in the code you have provided -

final buff = Uint16List.view(valueBytes.buffer);

so I'm not sure what this has fixed or why.

The definition of 'change' for an observed resource is defined by the server, not the client see here - 


1.4.  Observable Resources

   A CoAP server is the authority for determining under what conditions
   resources change their state and thus when observers are notified of
   new resource states.  The protocol does not offer explicit means for
   setting up triggers or thresholds; it is up to the server to expose
   observable resources that change their state in a way that is useful
   in the application context.

That said it looks as though we are not seeing the completion of registration and continually sending GET requests to re register because of it -

2020-12-28 10:55:34.490: INFO: >> Scheduling re-registration in 7000 ms for

This seems to be because we are not seeing the observe option in the response message although it is present in the log debug output, I'll dig a bit more into this.

shamblett commented 3 years ago

OK, I think I have fixed these two problems, the fixes are on the issue12 branch of the repo, please update your pubspec.yaml to reference this for your coap package and see how you get on now.

fulmineazz commented 3 years ago

I can't see this line in the code you have provided -

  1. I changed the 'intValue' method in coap_option.dart and it worked fine,but i don't know why. 
    /// Integer value
int get intValue {
if (valueBytes.isEmpty) {
  return 0;
}
if (valueBytes.length == 1) {
  return valueBytes[0];
} else if (valueBytes.length == 2) {
  final buff = Uint16List.view(valueBytes.buffer);
  return buff[0];
} else {
//      final buff = Uint32List.view(valueBytes.buffer);
  final buff = Uint16List.view(valueBytes.buffer);
  return buff[0];
}
}
  2. The second problem has not been fixed. After I get the first ACK type response, the client still sends the GET request to re register. I used the Copper plug-in on Chorme to simulate the client. After sending a GET request with the observe option 0, the server's first ACK response looks like this- 
    Time: 10:50:00
Type: ACK
Code: 2.05 Content
MID: 40323
Token: 0x16895BA
Options: Observe: 5418170, Content-Format: 0, Max-Age: 5
Payload: 10:49:56

    next CON type response from server (then we will get this response every 5 seconds and send ack to server immediately):

    Time: 10:50:01
Type: CON
Code: 2.05 Content
MID: 64122
Token: 0x16895BA
Options: Observe: 5418171, Content-Format: 0, Max-Age: 5
Payload: 10:50:01

    I notice that these responses all contain observe option and there is only one GET request had been sent.

shamblett commented 3 years ago

OK, I made a test from your code above using your test server -

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();
}

When run this gives the following log output -

EXAMPLE - Sending get observable request to wsncoap.org, waiting for responses ....

So we register a the observable then just receive response messages from the server, is this not what you expected?

That's exactly what I want. What puzzles me is that I'm running the same code but the output is not the same as yours... log output:
