Detect Bluetooth signal strength in Mac OS X

A few days ago we shared a way to detect the strength of WiFi signals on the Mac OS X platform, and many fans said it was practical. Today's small series to share with you the method of detecting Bluetooth signal, if you find that the Bluetooth connection is often interrupted, may come in handy.

The method for detecting the strength of a Bluetooth signal is simple:

Go to "System Preferences-Bluetooth";

Hold down the option key to see the Bluetooth signal strength.

The greater the number (the smaller the negative) the better the signal, such as the 20 signal is much better than the 90 signal. However, it should be recalled that the battery of the Bluetooth device is also one of the determinants of the signal, such as your Bluetooth mouse and keyboard placed next to the MAC, but the signal is very bad, then you should check whether the battery is fast. Check the way is also very simple, in the "System Preferences" click the mouse and keyboard, the bottom left corner of the interface can see the remaining power.
