The most common Bluetooth frequencies are 2.4GHz and 5GHz. If you want to connect to the same frequency as another device, you need to set it in your device’s settings. For example, if you want to connect your phone, laptop, or tablet with your speaker, the best way is by setting both devices on the same frequency. However, it’s not possible for two Bluetooth devices with different frequencies to communicate with each other even if they’re close together Before deciding which Bluetooth frequency you will use for your devices, make sure they are all compatible with one frequency of your choice. 2. Ensure your device is in range of the Bluetooth signal.
