If it is a laptop, move your laptop closer to the device.

Check your devices support Bluetooth

It is all assumable that your computer or Bluetooth device supports wireless technology when actually it doesn't. Not all devices use Bluetooth or have the technology built into them, so check the device packaging or manual to see if it supports Bluetooth or not before trying to connect. Otherwise, you can connect using a cable or Wifi connection.

Sometimes it might also take time to scan or detect other devices, so if it goes off, turn it on again and try the connection.
