Open the Bluefruit Playground app on your iPhone or iPad. Read through the startup screens and tap the Begin Pairing button at the bottom.
The Finding CPB list will appear, showing all the compatible devices detected by the app.
The icon at the left of each device name represents its wireless signal strength (RSSI).
Tap the row titled Bluefruit52 to connect Bluefruit Playground to your CPB.
If your CPB doesn't appear on the Finding CPB list:
- Check to see if the CPB is powered on. Verify that the green On light is lit.
- Make sure CPB is running the correct firmware. See the Firmware page in this guide.
- Try resetting the CPB by pressing the small Reset button near the center of the board.
