MacOS 12.0.1 Monterey Bluetooth issues

Hi, I am an application developer for Mac. Our application uses bluetooth to connect to our hardware devices.

Since the upgrade to MacOS 12.0.1 Monterey Bluetooth is broken customer wide. Hence pairing works but our driver cannot connect (code worked for MacOS 10.7 - 11.3). The internet reports a lot of Bluetooth issues related to Broadcom BT on Monterey and the Bluetooth Framework has changed significantly by Apple.

  1. Where can I find detailed information about Apple's Bluetooth changes ?

  2. Should I just wait until Apple fixes this from their side ?

Any other guidance is appreciated.

Thank you?

    The Bluetooth Core on Monterey is buggy.

  • Hi!

    I don't have a solution but want to report the same problem here. Maybe this helps to get more attention. We also use bluetooth to connect to our hardware. Worked until 11.6.

Our production application has also been unable to create Bluetooth socket connections since the last update. We have validated this issue with two independent API for Bluetooth connection -- all of which are fully functional up to and including Big Sur.

Customers having upgraded to Monterey are all unable to connect their devices to our desktop application. This is critical and we are waiting for a fix.

  • Is Apple ever going to fix this bluetooth problem? since my mac updated I can no longer connect to my iphone which means i cant use airplay to transfer files from iphone to mac, strangely it works the other way round, so annoying, when i try to connect via bluetooh on my phone to my macbook i just get an error message saying my macbook isnt supported,

I installed 12.4 public beta about 6 hours ago but bluetooth hasn’t fixed yet. I think Apple did it on purpose to force people to buy new devices.

This is frustrating. it is still not fixed in 12.3.1 APPLE Please Fix it, or use a proper QA before release !!! Your devices such as Mouses, keyboards, etc ... are using BLE for connecting to your macs. !!

I have the same issue with electron apps with macosx 12.4 Beta (21F5058e); I can use the node library but if I compile it for electron it stops working. Same code works on Big Sur, I think it has something to do with plist permissions aswell but couldn't get them to work yet!

Hi guys. I had a same issue is that I couldn't connect my bluetooth earphone to my MacBook Pro M1 Monterey OS. However, I found a solution and I hope it will be worked for you. Follow my steps: Settings -> Network -> Advanced -> Hardware -> Configure: Manual; MTU: Custom; number: 1280.

That's all. try to reconnect your bluetooth devices. I hope it works :)

The phone's "Nokia PC Suite" Bluetooh service is not present on the macOS 12.3, this is a serious bug.

Not fixed in macOS 12.4

I am still facing issue connecting my bluetooth earbuds on M1 pro

Using v12.4 as of now. Has apple still not resolved this issue or anyone who found something?

@Ayeshiz I had this problem initially when connecting to Lego with this library, which in its turn uses some common Bluetooth dependencies https://github.com/nathankellenicki/node-poweredup

Not sure if it was both Apple and code base updates, but it has been working for me on 12.4 and 12.5 both M1 and Intel.

hope this helps to further investigate your problem.
