2 Get the APPS

Chessnut develops multi-platform apps (including Windows, Mac OS, Android, and iOS) for users to play with the Chessnut board. Many excellent third-party apps also work well with it. You can check the app list and get the download links on our website: https://www.chessnutech.com/pages/apps. [QR code for app download]

3 Connect the board to your devices

iOS and Android devices can be connected via Bluetooth, and Mac OS also supports wireless connection. Some Windows PCs may have different Bluetooth chips; some do not support BLE connection, and some cause unstable connections. Please use a USB cable on PC if you find you cannot successfully connect to your PC by Bluetooth.

Why can't I connect the board to my phone?

Please remember:

Enable GPS on your phone; the BLE connection relies on GPS [asterisk].
Allow location permission to the app.
You don't need to pair it in your Bluetooth settings as with usual Bluetooth devices. Just go to our apps and click the Bluetooth icon in the upper right corner; it will automatically search and connect to the device.
Ensure the blue LED on the board is flashing. If not, short press the power button [power-symbol] to enable it.

[asterisk] Chessnut will NEVER get or save your location data for any other use.
