Bluetooth is what your Mac uses to connect to wireless devices like keyboards, mice, trackpads, speakers, and other peripherals. Generally, it's a reliable technology. At some point however, the chances are you'll run into difficulty establishing a Bluetooth connection with one or more of your devices. Most problems can be fixed by unpairing and repairing the Bluetooth device, changing its batteries, rebooting your Mac, or performing an SMC reset. But if none of these methods work, you can always try resetting your Mac's Bluetooth module.
Here's how to do it in macOS using the hidden Bluetooth Debug menu. How to Reset Your Mac's Bluetooth Module Before proceeding, bear in mind that if your setup relies exclusively on Bluetooth for communicating with your keyboard and mouse, then you're going to temporarily lose connection to them using the following methods, so you might want to have a backup wired input device option just in case. Locate the revealed Debug submenu and hover your mouse cursor over it.
Click Reset the Bluetooth module. Now, restart your Mac. You'll notice a couple of other potentially useful options in the Debug submenu. Factory reset all connected Apple devices does exactly what it says — forces any Apple-branded Bluetooth accessories back to the default settings they came with out of the box. It's a reliable fallback option if you've tried everything else to fix a connection issue, including resetting the Bluetooth module.
Lastly, the Remove all devices option might prove useful if you're moving your Bluetooth mouse and keyboard to another Mac, for example. Removing devices in this manner means you're not also banishing a whole bunch of other established Bluetooth connections like speakers and so on that you might want to keep. Tag: Bluetooth.

During Apple's earnings call for the fourth fiscal quarter of this week, Apple CEO Tim Cook said he believed that the Apple Card had the "most successful launch of a credit card in the Somewhere I read about the batteries loosing their connection inside the mouse.
It sounded ridiculous. My batteries did not seem to be out of position in the battery slot. As a last desperate attempt I did fold a post-it note and stick it between the batteries and the battery cover. I know some of the issues mentioned in this thread are different than what I have experienced, but my hope is that some will find this page from a Google search. I started experiencing keyboard, mouse and trackpad on my iMac simultaneously dropping out recently.
Sometimes it was for a few seconds, sometimes much longer and quickest way to resolve tended to be reboot. Apple support failed to diagnose the problem but then I stumbled across a comment on the internet that an app called Android File Transfer was a potential cause.
Since deleting this app my Mac has been fine.

SO beware this app used to backup my wife's phone. Thanks to Keith it seems my problem got solved! My disconnects of both keyboard and mouse started when I installed that "Android File Transfer" app. Also unlocking with Apple watch works again, which it didn't for the last couple of days since I installed this damn app. Does anyone else have the same experience? Maybe someone else has a different app that interferes with bluetooth like this? Not connecting after sleep. All seems fine now. If so - great tip.
Have not seen this mentioned anywhere else as a possible cause. I saw your question on apple support forums, I used to have a similar issue. Occasionally my bluetooth would also get stuck on, as in, I was unable to power off bluetooth either in the menu or from blueutil.
Start with the simple stuff
When another device is discovered, a connection is established and some basic metadata is exchanged device model, manufacturer, mac address, battery level, device local time. The process which handles these interactions is wirelessproxyd, and you can see in your console log that it is running and discovered an apple device and exchanged some metadata..
There are several ways in which this information is used by your device, most notable is geolocation when no GPS satellite signal is available. When your inside your house and look at your location in maps, it knows straight away that you are home because it can see that a familiar fixed device is nearby ie. Similarly, those fixed devices detect your phone and make the assumption that you are at home and feed the information to homekit for location based smart device control and location based reminders, handoff etc.
There are also some nefarious ways this information is used also. There are devices which exist which scan and log all nearby wireless signals bluetooth, wifi RFID etc.

They're marketed to shopping centres, retail stores and hotels for the purpose of targeted advertising and analytics. It also worth noting that BTLE has been actively exploted in the past by malware and hackers, and many vulnerabilities existed in many devices which allowed an attacker to gain access and execute malicious code.
These were actively exploited in the wild by the BlueBorne and BlueJack malware and HackingTeam's RCS surveillance platform, which is used by law enforcement around the world. Those particular vulnerabilities have since been patched on all recent Apple devices. Now i'm sure the following solution is probably not recommended by the Apple support community, which is why I gave you the background information above, so you can consider your particular situation and decide for yourself whether this solution is right for you.

I only use one bluetooth device with my iMac, a magic mouse 2, its operation has been perfect since. I don't use airdrop or any other bluetooth features. FYI - I also disabled bluetoothaudiod, wifivelocityd, AirplayXPCHelper, I figured that the less funtions using the broadcom wireless chip the less wireless interference and less bluetooth bandwidth in use etc. Not sure why but connected to MacBook Pro , the AirPods signal drops at about 20 feet already at home.
The connection with iPhone same location as the Macbook Pro seems to be much solid. No clue why.

I am having Bluetooth disconnects continuously throughout the day on my MBP Apple Magic Mouse disconnects and reconnects. The mouse is literally within 6 to 8 inches of the laptop when this happens. I switched it out with a new Magic Mouse and still have the same problem. The issue occurs both at the office and at home.
MacBookPro15,1 Intel Core i7, 2. I don't really use any other Bluetooth devices other than occasional hotspot from my iPhone. Whenever it happens, the mouse will disconnect for 2 seconds, then immediately reconnect, then disconnect for another 2 seconds and reconnect. Not sure what else to try as it seems to be a hardware issue. Seems like a very expensive computer to have such a fault. I also have the same problem with my iMac 27 late with Mojave I have reported to Apple Support. I was experiencing the same BT audio dropouts that many people have reported.
After much googling and crawling through logs, it looks like possibly some timeout issue between wirelessproxd which scans for nearby BTLE devices and sharingd AirDrop and Handoff. I have read one report of solving the problem by disabling Handoff, but that didn't work for me.
