[iOS] Connect to device doesn't seem to respect timeout

[cbreezier]

      try {
        await device.connect(timeout: Duration(seconds: 3));
      } catch (e) {
        debugPrint('Failed to connect to device: $e');
        Util.showError(context, 'Failed to connect to device');

        return await onError.call(device, e);
      }

device is a Peripheral object. This dart code works fine on Android, where a connection attempt is cancelled after 3 seconds and an exception is thrown (and caught).

However, the same code doesn't seem to do anything on iOS. The connection attempt seems to last forever.

Is the timeout parameter supported on iOS?

It should work the same way. https://github.com/Polidea/MultiPlatformBleAdapter/blob/master/iOS/classes/BleModule.swift#L400

i have the same issue

@cbreezier @dokinkon As a workaround you can use Dart's timeout method: await device.connect().timeout(Duration(seconds: 3));

If you have some issues with scanning or connecting to the device once it's available/in range again, also add this hack:

try {
   await device.disconnectOrCancelConnection();
} catch (e) {}

No news, sorry. I'll try to fix it this month.

Almost a half year later, but the issue will be fixed in the nearest release, probably by the end of the week.
