L2Cap

Implements L2Cap channel capability in Core Bluetooth.

Usage

Instantiate L2CapCentral to discover and connect to peripherals

    self.l2capCentral = L2CapCentral()
    
    self.l2capCentral.discoveredPeripheralCallback = { peripheral in
        self.peripheral = peripheral
        self.l2capCentral.connect(peripheral: peripheral) { connection in
            self.connection = connection
            
            self.connection?.receiveCallback = { (connection,data) in
                print("Received data")
            }
            
            self.connection?.sentDataCallback = { (connection, count) in
                print("\(count) bytes sent")
            }
        }
    }

Send data by calling self.connection.send(data: data)

Instantiate L2CapPeripheral to advertise a peripheral and accept connections from centrals

    self.peripheral = L2CapPeripheral(connectionHandler: { (connection) in
        self.connection = connection
        self.connection?.receiveCallback = { (connection, data) in
            DispatchQueue.main.async {
                self.bytesReceived += data.count
            }
        }
    })
