How to fix Bluetooth connection errors

The Bluetooth connection allows us to link devices with devices and also with peripherals . In iMac , without going any further, the mouse or trackpad, as well as the keyboard, are connected via Bluetooth. In general, it is a technology that works perfectly, but when it shows a fault it is quite difficult to know why it fails and how to fix it.

Diagnostic menu to the rescue

The options that we normally try when a Bluetooth device has a connection failure are, in general, to turn it off and on again, restart the computer or disconnect and reconnect the device . When all this fails we will use a little more forceful systems: the Bluetooth diagnostic menu.

The first thing we have to do is make sure that in the menu bar we see the one that corresponds to Bluetooth. We will do it with these steps:

  1. In the Apple menu () we choose System Preferences.
  2. We enter Bluetooth.
  3. We activate the Show Bluetoothoption in the menu bar .

At first glance, this menu allows us to connect the different linked devices, disconnect them, activate or deactivate the Bluetooth antenna itself or access the preferences panel. If we want to see more options we just have to hold the alt / option () key while we click on the menu . In doing so we will see additional information appear, such as the MAC address of the module and if the visible mode is activated. Let’s go one step further and access the diagnostic menu.

  1. We hold down Shift (⇧) + alt / option (⌥)
  2. We click on the Bluetooth menu.

In doing so, we will see that the Debug option appears in the menu, which offers us three options: Reset the Bluetooth module , Reset the factory settings on all connected Apple devices and Delete all devices . Before continuing, a note of the utmost importance for all of us who use a computer whose keyboard and mouse / trackpad connect via Bluetooth: it is important that we have a mouse or keyboard that is connected by cable at hand to control the computer if something goes wrong with Bluetooth.

How we use the Diagnostics menu

The options are self explanatory, trying to resolve any connection error we will first try to remove all devices and reconnect them. If the error still continues, we will try to restore the factory settings on all connected Apple devices , in this case it is important that the device that gives connection errors is currently connected to the Mac so that the computer can send it the order to Hola.

Finally, the option to reset the Bluetooth module , which we will use as a last resort, allows us to completely reestablish the bluetooth connection of our Mac. After doing so we must restart the Mac and reconnect the peripherals , it is important here to have a mouse or wired keyboard so you can continue to interact with your computer.
