I just got my Bluefruit board and when I run a sketch it hangs forever on the 'Connecting...' stage!

There are several possible explanations here, but the first thing to try is to:

1. Disconnect and close the Bluefruit LE Connect app if it's open

2. Disable BLE on your mobile device

3. Restart your Bluefruit sketch and HW

4. Turn BLE back on again (on the mobile device)

5. Open the Bluefruit LE Connect mobile app again and try to connect again

If problems persist, try performing a Factory Reset of your device (see the appropriate learning guide for details on

how to do this since it varies from one board to another).
