Implements L2Cap channel capability in Core Bluetooth.
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
}
}
})
