What happened?

I'm using setNotifyValue when im getting data from BLE device. When i set this value i get some errors.

try{ await buttonCharacteristic.setNotifyValue(true); } catch(e){ print("ButtonChar $e"); }

I used this like that for an exception and im getting these errors :

try using the example app!

I/flutter (14956): [FBP] <setNotification> args: {remote_id: 84:F7:03:1B:DD:E6, service_uuid: 0000181a-0000-1000-8000-00805f9b34fb, secondary_service_uuid: null, characteristic_uuid: 00002a37-0000-1000-8000-00805f9b34fb, enable: true}
I/flutter (14956): [FBP] <setNotification> result: null
I/flutter (14956): [FBP] [[ OnDescriptorResponse ]] result: {secondary_service_uuid: null, error_string: GATT_SUCCESS, service_uuid: 0000181a-0000-1000-8000-00805f9b34fb, success: 1, remote_id: 84:F7:03:1B:DD:E6, descriptor_uuid: 00002902-0000-1000-8000-00805f9b34fb, error_code: 0, type: 1, characteristic_uuid: 00002a37-0000-1000-8000-00805f9b34fb, value: }

^ these logs are interesting. OnDescriptorResponse returned success, which means <setNotification> succeeded, but the value in the result is empty. I am not sure why that would be. It is supposed to return the new value of the descriptor.

Perhaps your device has bugs!

chipweinberger commented 1 year ago

did you figure it out?

umuttsaltan commented 1 year ago

No, i don't know what's the problem. Tried too many things but same error.

Sample function from my code :

void powerChar() async { final powerServiceUuid = Guid("0000181a-0000-1000-8000-00805f9b34fb"); final powerCharacteristicUuid = Guid("7e422156-ab78-11ed-afa1-0242ac120002");

for (var service in servicesList) {
  if (service.uuid == powerServiceUuid) {
    BluetoothCharacteristic? powerCharacteristic;

    for (var characteristic in service.characteristics) {
      if (characteristic.uuid == powerCharacteristicUuid) {
        powerCharacteristic = characteristic;
        break;
      }
    }

    if (powerCharacteristic == null) {
      print("Power characteristic not found.");
      return;
    }

    try {
      await powerCharacteristic
          .setNotifyValue(powerCharacteristic.isNotifying == false);
    } catch (e) {
      print("Power Char: $e");
    }

    powerCharacteristic.lastValueStream.listen((power) {
      if (power.length == 2) {
        int powerdata = (power[0] << 8) + power[1];

        dataDeviceController.powerData[currentDeviceIndex!] =
            powerdata.toString();
      }
    });
  }
}

}

Am i doing something wrong ?

chipweinberger commented 1 year ago

the problem seems to be your bluetooth device, not your flutter code.

umuttsaltan commented 1 year ago

I checked the device, descriptors allows only read. Could this be the problem ? Does package trying to writeDesc when setNotify ? If thats the problem can i fix this, change anything on device software ?

chipweinberger commented 1 year ago

that is a problem. you must change device firmware

chipweinberger commented 1 year ago

did you fix it?

umuttsaltan commented 1 year ago

No, my friend works on device firmware. I said the problem, after he change the firmware i'll try it again.

chipweinberger commented 1 year ago

does it work on iOS?

flierville commented 1 year ago

Hello, I am joining this conversation because I have encountered the same error message since I upgraded from version 1.4.0 to version 1.14.23

Before with version 1.4.0 it worked with my BLE device (this is not a problem on the device side) (android, flutter 3.13)

When upgrading to version 1.14.23 the only ones I changed concern the connection (static call, method name etc.)

Thanks for your help

chipweinberger commented 1 year ago

So it turns out there was a bug in FBP.

Android actually deprecated the API we were using, because it made this bug easy to make.

In short, descriptor.getValue() can only be reliably called after a READ, not a WRITE.

I've fixed this on master branch. please try it: e270e09dc68fee0296b90b6933258b73ca34f6b8

I have updated to 1.14.23, but the error is still reported on Android, but it is normal on iOS.

chipweinberger commented 1 year ago

@brain9520 , you must use master branch

dependencies:
  flutter:
    sdk: flutter
  your_package_name:
    git:
      url: https://github.com/boskokg/flutter_blue_plus
      ref: master
brain9520 commented 1 year ago

According to what you said, the error is no longer reported, but there are other problems, I will try to solve it myself first, thank you. Then I have another question, that is, flutter_blue_plus does not seem to have duplicate devices when scanning on iOS, but many duplicate Bluetooth devices will appear when scanning on Android. Is there a parameter that can be turned off and set to not repeat scanning.

chipweinberger commented 1 year ago

but there are other problems

what problems?

Then I have another question, that is, flutter_blue_plus does not seem to have duplicate devices when scanning on iOS, but many duplicate Bluetooth devices will appear when scanning on Android. Is there a parameter that can be turned off and set to not repeat scanning.

please file a separate issue, with logs & screenshots

chipweinberger commented 1 year ago

@brain9520 that issue not not related to notifications, and should not be in this thread. please file seperate issue

chipweinberger commented 1 year ago

fixed in 1.14.24

Zqiang12345 commented 11 months ago

I also found this problem. My problem is caused by setting mtu. When setting setNotifyValue, I have to wait for mtu setting to complete before using it
