We upgraded a notebook to Monterey 12.4.
Its bluetooth immediately failed after the update (cannot be switched on/activated anymore).
The console displays:
bluetoothd SetPowerState failed: BT_ERROR_NOT_IMPLEMENTED 'Power on failed''
MacbookPro Retina, 13.inch Early 2015, upgraded directly to 12.4
Are there any news on this issue?
NOT IMPLEMENTED is no indication of a hardware issue!
MacBook Pro 15″, macOS 10.15
After resetting the NVRAM followed by the upgrade to 12.5 Monterey bluetooth started working again. First devices showed up only as HEX numbers. Then after deleting them devices were found by name and it started working again. Thanks for the hints.

Trying resetting NVRAM.
Keep holding down Command-Option-P-R while starting your mac and let the startup chime sound some four or five times, then release the keys and let your mac finish the startup, and see if there is any change.
If the issue persists: Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.
Follow advise from contributor @Luis S first.
Hardware from 2015 in 2022 = 7 year old machine. It may or may not be showing its' age as hardware is starting to acting up
Aside - July 20, Wednesday Apple Released Monterey 12.5
Though, that may show up in the EtreCheck Report
Age related problems should not show up directly after an upgrade with the a console message "not implemented".
And exactly the fact that 7 years old hardware is still working perfectly and reasonably fast is one of Apple's USP and makes the high price tag compared to the competition worth.
Good, the SMC or NVRAM reset fixed the issue and all is good.
IMHO - 7 year old machine, the number of UpGrades this computer has experienced in its' lifetime tends to bear out certain inevitable facts.
Anything outside of the Technical Apple Issues - No comment
