Usage

Create RxEAAccessoryManager instance:

let rx_manager = RxEAAccessoryManager()

Available actions:

// tries to open session with first match from available accessories for given `supportedProtocols`
rx_manager.tryConnectingAndStartCommunicating(forProtocols: supportedProtocols)

// tries to open session for given `EAAccessory`
rx_manager.tryConnectingAndStartCommunicating(to: accessory, forProtocols: supportedProtocols)

// stops any working sessions
rx_manager.stopCommunicating()

You can observe:

// available accessories - Observable<[EAAccessory]>
rx_manager.connectedAccessories
    .subscribe(onNext: { accessories in
        // DO SOMETHING
    })
    .disposed(by: disposeBag)

// current opened session (nil if any session on) - Observable<EASession?>
rx_manager.session
    .subscribe(onNext: { session in
        // DO SOMETHING
    })
    .disposed(by: disposeBag)

// calls from `StreamDelegate` - Observable<StreamResult> where StreamResult = (aStream: Stream, eventCode: Stream.Event)
rx_manager.streamResult
    .subscribe(onNext: { stream, eventCode in
        switch (stream, eventCode) {
        case (let inputStream as InputStream, .hasBytesAvailable):
            // DO SOMETHING
            break
        default:
            break
        }
    })
    .disposed(by: disposeBag)
