If you are to use mBlock 5 on a PC that runs Windows and is equipped with a non-Bluetooth 4.0 protocol, you need to use a Bluetooth 4.0 dongle to connect a device to mBlock 5. Check the Bluetooth version of your PC before performing other operations.

If you are to connect CyberPi, Halocode, or Codey Rocky to your computer directly through Bluetooth, the Bluetooth protocol on your computer must be Bluetooth 4.0 or later. If your computer is equipped with no Bluetooth adapter or the Bluetooth protocol is earlier than 4.0, consider purchasing the Makeblock wireless adapter or a kit including the Makeblock wireless adapter.**
