mojave bluetooth issues

I now tried to delete the Android app, but it still freezed for few seconds after (my) nap. True I did not restarted the mac as it was finishing something.

It behaves as if the bluetooth goes into a kind of saveenergy/sleep mode and have trouble to wake up, In fact it happens usually in two cases:

• when I try to restart working after some time (and as the screen is dark only way is to push on button to discover the BT does not work)
• after few minutes of work.

I was also wondering if it is fault of VmWare fusion (I have use of virtual machines), but cannot find reference in this regards.

I will check what happens in the next 24 hours after a restart to see if it was android, then I would start the Handoff.

Thanks!

not sure of this.

Removing the auto off function solved all my problems (I still have not reinstalled Android tool to double check, but I'm confident)

possibly there are several causes and several solutions depending on the individual cases.

Finally, some indication that Apple might recognize and be addressing the issue. My fingers are crossed.

Meanwhile, it sounds like you have had the same experience with a senior technician who "owns" your issue. I am disappointed to hear that someone else has had the same experience with those who have told us they are responsible for helping us resolve issues. At a minimum, I don't think it is unreasonable that these case owners would contact customers with whom they have spoken about what is now a known issue.

You're welcome, the real credit goes to the poster who found the problem app.

Perhaps I spoke a fraction too soon. I experienced a very brief loss of bluetooth (<1 minute) this morning. Not as bad as what I had been experiencing, but makes me nervous

I too have been experiencing the exact same symptoms. I have even updated to 10.14.2 which has not helped.

Bluetooth goes down and I have not figured out how to get it reloaded without a restart.

I am afraid to say that the problem still exists on MacOs Mojave 10.14.3...

The above, stopping BT from going to sleep did the trick for me - Thank you ! Was very frustrating !

I might have find a new solution.

When I said hereunder that I had the feeling it was as if BT was going to sleep I checked my energy saving options. In fact I did because I noted that when the screen was off the entire machine was pausing (stopping some copy job in a virtual machine).

So I ticked the option to prevent Mac to stop just because the screen went off. See pick, it's in Italian but the position of the option is the same in every language.

Since yesterday I had no problem, while simply removing the Android FT did not solved completely (I had a BT short blackout once) NB: I still have to reboot the machine, so restarting after changes is not related in my case.

If this stabilize I will try reinstalling Android FT and see.

I have had 4 calls with Apple support, and have had my calls escalated up at least one level. This solution, turning on "Prevent computer from sleeping automatically when the display is off," seems to have solved my problem. (The issue with Android did not apply to my case.) After several times per day disconnections, and twice having Bluetooth being unavailable, I have had two successful days with no interruptions. So thank you for the help.

I bought a 2018 iMac 27" 5K and I am in the same boat as you. Upgraded to Mojave in the hope that it will be fixed but it seems to happen more often. I am really disappointed as it seems calling Apple or getting parts or the computer replaced does not do much more than wasting our time.

Every solution that was posted online I have tried. Given the randomness of the fault (sometimes after wake up) it suggests it is a software fault (never happened from cold boot and almost never while working). In my system, BT returns spontaneously after a while (one or two minutes).
