1 | # L2CapDemo
2 | Demonstration of using Core Bluetooth L2CAP channels in Swift on iOS. Use the [L2Cap swift module](https://github.com/paulw11/L2Cap)
3 |
4 | You will need two iOS devices to run this demo. Bluetooth is not supported in the simulator.
5 |
6 | On one device, turn on the *Scan* switch - this device is the central that will look for a peripheral
7 | On the other device, turn on tyhe *Advertise* switch - This device is the peripheral.
8 |
9 | Once a connection is made, text entered into the text field on the central will be displayed on the peripheral when you tap *Send*
