bluetooth not turning on

I am frustrated too by bluetooth issues - I am on macOS Mojave 10.14.6 on an iMac 21.5 late 2012

First of all my keyboard or mouse tells me - connection lost- after a few minutes when not touching any key or mouse movement.

Usually I put him/her/it to sleep when absent for a break. After the break I cannot wakeup the iMac with a keystroke nor moving the mouse. Only thru restart I can get out of that trouble.

I see that last posts are from 2019 - now in 2022 still same sh...? I tried the given workarounds - no luck.

I can not upgrade to newer macOS Versions (hardware to old)

Q - " I am on macOS Mojave 10.14.6 on an iMac 21.5 late 2012 "

Q -" I can not upgrade to newer macOS Versions (hardware to old) "

A - macOS Catalina 10.15 hardware requirements this computer does Qualify to run Catalina macOS 10.15

A - Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.

Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.

@P.Phillips I am refering to this thread

Bluetooth not connecting after Mojave 10.… - Apple Community last posts Dec 2019.

Obviously no solution was presented. Not even an upgrade to Catalina -which someone did- resolved the problem.

I checked hardware requirements for my iMac.

As for today I can say that powering down the iMac with no bluetooth keyboard / mouse powered on resovled the problem. After power on I was asked to present a keyboard and voila it activated bluetooth connection
