Hanging on "async with BleakClient..."

• bleak version: 0.5.0-develop
• Operating System: macOS 10.14.6 (on early 2015 Macbook Air)

Description

In running the examples on MacOS, everything hangs after/within async with BleakClient(address, loop=loop) as client: (within run) i.e. the subsequent typical example x = await client.is_connected or any other calls do not appear to run. Despite this, the OS does indicate that the BLE device is connected indefinitely until the script is stopped. Everything appears to be working fine on Windows.

I will include the changes in #213 in a version 0.7.X release as soon as someone confirms that it is still present.

Hello, I can confirm that the issue is still present for me with v0.7.0 on macOS 10.14.6. I updated to bleak 0.7.0 and was still having this problem. I added this line as a workaround and it seems to have solved the issue for me:

if not self.connected_peripheral_delegate:

Here is the context:

@objc.python_method
def did_connect_peripheral(self, central, peripheral):
    logger.debug(
        "Successfully connected to device uuid {}".format(
            peripheral.identifier().UUIDString()
        )
    )
    if not self.connected_peripheral_delegate:
        peripheralDelegate = PeripheralDelegate.alloc().initWithPeripheral_(peripheral)
        self.connected_peripheral_delegate = peripheralDelegate
        self._connection_state = CMDConnectionState.CONNECTED

I have merged #227 into develop and will make a version 0.7.0 release later today with those changes as well as a lot of others. If the “fire twice” problem is still left after release of version 0.7.0, I will include the changes in #213 in a version 0.7.X release as soon as someone confirms that it is still present.
