Peripheral connected through the system never connects if not advertising

[Florian Bürger]

I am not too familiar with the internal workings, so maybe I am missing something: We upgraded to the recent version, but all our tests are breaking now because a mock peripheral that is already connected by the system never connects.

Looking through the diff, it seems the manager now only set mock.state = .connecting. The actual connection is only triggered in static CBMCentralManagerMock.peripheralBecameAvailable(_:) which is called when a peripheral is advertising. Previously, the connection was established during the CBMCentralManagerMock.connect(_:options:).

Our peripheral does connect to iOS in the background without any involvement from our app. The peripheral stops advertising when connected. Our mock looks like this

CBMPeripheralSpec
	.simulatePeripheral(proximity: .near)
	.advertising(
		advertisementData: [
			CBMAdvertisementDataServiceUUIDsKey: (...)),
			CBMAdvertisementDataLocalNameKey: "Mock",
		],
		withInterval: 0.250,
		alsoWhenConnected: false
	)
	.connected(
		name: "Mock",
		services: [(...)],
		delegate: MockSpecDelegate()
	)
	.build()

If I revert the change in CBMCentralManagerMock:728

mock.state = .connecting
mock.connect() { result in
  switch result {
	case .success:
		self.delegate?.centralManager(self, didConnect: mock)
	case .failure(let error):
		self.delegate?.centralManager(self, didFailToConnect: mock, error: error)
}

everything works again.

Is this an oversight? Or am I missing something? Is there a new way to simulate this use case?

Hello,

First of all, sorry for the delay. I missed your post.

You have a valid point. I will update the library. If the device is already connected, the connection should happen even if the device is no longer advertising.
Expect 0.16.1 soon.

[Aleksander Nowakowski]

The version is now tagged. I'm releasing 0.16.1 on CocoaPods now. Please, give it a spin. Your issue should now be fixed.
Additionally, the fix also includes fast connection to already connected devices.
