Registry lastConnectedPeripheral is always nil

[drdaz]

I've got the following code:

    self.bluetoothDeviceManager = [WLXBluetoothDeviceManager deviceManager];
    id<WLXBluetoothDeviceRepository> repository = [[WLXBluetoothDeviceUserDefaultsRepository alloc] initWithUserDefaults:[NSUserDefaults standardUserDefaults]];
    WLXBluetoothDeviceRegistry * registry = [self.bluetoothDeviceManager deviceRegistryWithRepository:repository];
    registry.enabled = YES;
    [registry fetchLastConnectedPeripheralWithBlock:^(NSError *error, CBPeripheral *peripheral) {
        if (peripheral) {
            // Connect
            [self connectToPeripheral:peripheral];
        }
        else
        {
            // Discover
            NSObject<WLXDeviceDiscoverer> *discoverer = self.bluetoothDeviceManager.discoverer;
            discoverer.delegate = self;
            [discoverer discoverDevicesNamed:@"MyDeviceName" withServices:nil andTimeout:30000];
        }
    }];

Later on in the flow, I consistently get a connection. But the peripheral variable in the fetchLastConnectedPeripheralWithBlock always comes back nil on next run. In addition the wiki says there's a property called lastConnectedPeripheral on the object we should use, rather than the block-based method.

When the peripheral parameter in the block passed to fetchLastConnectedPeripheralWithBlock is nil do you also get nil in the error parameter?

After checking the code, I realized that the documentation was not up-to-date. The main responsibility of the registry is just to listen to connection event and save the peripheral in the corresponding repository. I would update the documentation to say that fetchLastConnectedPeripheralWithBlock should be used.

Both variables are nil, yes.

OK that is weird and definitely a bug. I am gonna try to reproduce that and see where the bug is.

I cannot find a way to reproduce the bug, would you mind sharing your example project @drdaz ?

Here... use the .xcworkspace file to open the project.

@drdaz Try using this project https://github.com/Wolox/WLXBluetoothDeviceExample. I will connect to the first device that founds and then I will fetch it from the local repository. Let me know if you can reproduce the bug with that project.

Remember to run carthage bootstrap --platform ios
