BLE Serial IOs Example

This is a simple app, which scans for BLE Peripherials and connect to them. The example works with NORDIC_UART_SERVICE.

UUIDS

Here are the UUIDS:

SERVICE_UUID: "6E400001-B5A3-F393-E0A9-E50E24DCCA9E"

CHARACTERISTIC_UUID_RX: "6E400002-B5A3-F393-E0A9-E50E24DCCA9E"

CHARACTERISTIC_UUID_TX: "6E400003-B5A3-F393-E0A9-E50E24DCCA9E"

How to Run the App

Clone the source code and open it in xCode. You'll need an apple computer and an actual iPhone to run it. The emulator wont work with BLE. Connect an iPhone with a USB cable and run the application and scan for devices.
