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.
