Unstable connection after restarting the app #57

Closed ChrisMarxDev closed 2 years ago

ChrisMarxDev commented 2 years ago

Sometimes when I restart the app and call the reconnectDevice() function. The connectionStateStream() will send a connected event and even the isConnected() function returns true. But when I then call any function that actually reads or writes data from/ to the watch (e.g. startEcgMessuringWithDuration(int duration) or getDeviceBaseParameter()) nothing happens.

Danny23523 commented 2 years ago

It should be confirmed with the bluetooth library from the third party

ChrisMarxDev commented 2 years ago

What exactly should be confirmed? Are you going to confirm that?

Danny23523 commented 2 years ago

The bluetooth library is what your team requested, not ours, so you need to confirm with the party who provide the library for you.

Danny23523 commented 2 years ago

To confirm with them why the connection is unstable

ChrisMarxDev commented 2 years ago

Okay, then I was lacking some information. I thought that your team is fully responsible for ensuring that the bluetooth connection with the watch works.

Danny23523 commented 2 years ago

Nonono, as the third party library is what your engineer requested, so we don't have rights to change it, please check.

YongHealyWorld commented 2 years ago

Hi @Danny23523 , the followings are included in the invoice (Oct 2021). Pls help ensure the function and fix the ticket. Thank you.

Major Key Points

  1. The SDK should automatically reconnect to Healy Watch if App is started
  2. The SDK should automatically reconnect to Healy Watch if Bluetooth is disabled and enabled
  3. The SDK should automatically reconnect to Healy Watch if Bluetooth is lost range and again in range
Danny23523 commented 2 years ago

I see, but because which is what your engineer asked to use that library, You need to also try to contact with them for solutions.

Danny23523 commented 2 years ago

We will also try to contact with them about the unstable connect problems, if they can update the library, then we will also update the SDK for you.

Danny23523 commented 2 years ago

The third party still didn't feedback so far, we are working hard to contact with them to solve the problem, how about your side?

ChrisMarxDev commented 2 years ago

I had a look at some of the open issues on the third party library, but since I don't know what is going on inside of the watch, I can't really tell what I am looking for. So I didn't achieve any progress on this. For me as a user of the watch sdk I can only see that the watch shows that it is connected and the watch sdk functions don't work, which could also be an issue of hardware software compatibility.

Danny23523 commented 2 years ago

The engineer already contacted with the third party to find a solution, but didn't get response. If you are a user, why your team ask to use that bluetooth library before? Can you confirm?

Danny23523 commented 2 years ago

Sometimes when I restart the app and call the reconnectDevice() function. The connectionStateStream() will send a connected event and even the isConnected() function returns true. But when I then call any function that actually reads or writes data from/ to the watch (e.g. startEcgMessuringWithDuration(int duration) or getDeviceBaseParameter()) nothing happens.

Hi, Chris, as we still didn't get the response from third party, could you please tell more details about this problem, how often it happens? It's a must phenomenon or just happened randomly?Is there any code can share for testing? As our engineer cannot get it happened as what you met, if you can share some code for reference, maybe they can help give some suggestions.

ChrisMarxDev commented 2 years ago

I have encountered this error pretty randomly. But I can tell you that it only happens with reconnected devices. So all devices that are instantiated work fine, but after killing the app or putting it in the background and reconnecting with the reconnect() function, I sometimes reach this state. And while this state occurs quite randomly and rarely, it does break the whole experience of the app.

Danny23523 commented 2 years ago

Android or IOS？The engineer need to check the Phenomenon, then know how to solve

ChrisMarxDev commented 2 years ago

Mostly on Android as far as I can tell. Do you have a detailed documentation on how reconnection should be handled, especially when putting the app in background and foreground again? Then we could maybe now if there are issues with how we use the library. Currently we will just call the reconnect() function when the app enters the foreground, but the connection state does not seem to be established correctly. This make the app unreleasable for us.

Danny23523 commented 2 years ago

Ok, we will check the android app, and let you know how to solve, we expected to reply tmr.

YongHealyWorld commented 2 years ago

Request from Jstyle @Danny23523 : the issue your engineer feedback is difficulty to make it occur, possible to send a video for reference?

@ChrisMarxDev , @BradKwon : is this bug repeatable? If yes, pls provide a video recording as requested above (+ further possible/availlable details). If no, the ticket could be closed.

Thank you all!

BradKwon commented 2 years ago

@Danny23523 I cannot reproduce this issue on Android. There were some changes on our side as well and might occur rare and might be hard to reproduce at the moment. I think this issue can be closed for now unless we are able to reproduce it.

But, I have other two issues arisen. Please check them.

1. On iOS, the watch cannot be connected if it is previously paired to the phone.

-> If I do it like below steps, the watch is not scannable anymore so cannot connect the watch. The below steps are done on HW2 because your iOS example app crashes when I connect the watch with this error

reactive_ble_mobile[/PluginController.swift:163](): Assertion failed

  • thread 1, queue = 'com.apple.main-thread', stop reason = Assertion failed frame #0: 0x0000000186bdcd7c libswiftCore.dylib_swift_runtime_on_report libswiftCore.dylib_swift_runtime_on_report: -> 0x186bdcd7c <+0>: ret libswiftCore.dylib_swift_reportToDebugger: 0x186bdcd80 <+0>: b 0x186bdcd7c ; _swift_runtime_on_report libswiftCore.dylib_swift_shouldReportFatalErrorsToDebugger: 0x186bdcd84 <+0>: adrp x8, 335437 0x186bdcd88 <+4>: ldrb w0, [x8, #0x2f4] Target 0: (Runner) stopped. Lost connection to device. Exited (sigterm)

Steps: 1) Run iOS app with this watch Sdk (so, HW2) 2) Click "OK" on Bluetooth permission native dialog 3) Click "OK" on find and connect to devices on your local network permission native dialog 4) Connect watch in the app 5) Click "OK" on native pairing dialog 6) Click "OK" on native notification access permission dialog 7) Watch connection status it connected in the app and it works fine. 8) Kill and open the app (so, cold start) 9) Watch is not automatically re-connected although the watch displayed it is paired (green dash icon at the top-left side of watch device screen) 10) Your watch Sdk tries to re-connect the previously connected device by toConnectExistId() in bluetooth_connection_util.dart. But the watch already paired is not scannable so no scanned device sent. 11) I confirmed that it works when I don't pair the watch to the phone by clicking "Cancel" on native pairing dialog

2. What are the purposes of these delays? If it is optimizable, please reduce the delay as we don't need it if it is unnecessary. And please also add a comment on the line why we need this delay.

1) 1s delay at line 531 in bluetooth_connection_util.dart

await Future.delayed(Duration(seconds: 1));

if (_connection != null) {
  log(
    'already connecting to device: $device',
    name: loggerName,
    time: DateTime.now(),
  );
  return;
}

2) 1s delay at line 665 in bluetooth_connection_util.dart

  await Future.delayed(Duration(seconds: 1));
  await _connection?.cancel();
  _connection = null;

3) 2s delay at line 733 in bluetooth_connection_util.dart

await _connection?.cancel();
_connection = null;
await Future.delayed(Duration(seconds: 2));
if (bleManager.status == BleStatus.poweredOff ||
    isFirmwareUpdating ||
    device == null) {
  return null;
}
Danny23523 commented 2 years ago

Hi, Brad, If you cannot reproduce this issue on Android, then please close it. For your new question, yes, if the Bluetooth paired with phone, the bluetooth cannot be searched, all device like this, you can also try the App we developed before. In this case, you must unpair it first, then the bluetooth can be searched by app.You must unpair it with the phone first, then reconnect with the app.
