Q: Bluetooth not connecting after wake up from sleep

This morning, post Lion install, none of my bluetooth devices would connect automatically - keyboard, mouse, trackpad. I was left to plug in a wired keyboard and restart the computer.

 

Had never done this with Snow Leopard.

I fixed the problem by trashing my bluetooth preferences file and rebooting. Has been working fine ever since.

    Same here with Magic Trackpad. Reboot was required.

     

    I am providing feedback as a bug report using the feedback page for the Magic Mouse (which I don't have, but is obviously also a Bluetooth device like the Trackpad):

    The form's drop down menu also doesn't have an option yet for Lion, so be sure to make clear you're talking about Lion if you also use the form to report this

    Potential FIX.  My magic mouse was not connecting after my late 2008 macbook (10.7 Lion) would come back from sleep.

     

    I went to bluetooth preferences, removed my bluetooth devices, and repaired them. 

     

    Problem has not recurred.  I hope this works for others.

    Solution Found: Remove the batteries from your trackpad and re-insert. Then the bluetooth settings will discover the trackpad. Trashing the preference file did nothing for me but remove the bluetooth settings from my preferences.

    The problem you are likely seeing is due to a bug in Lion, I've worked around it by checking the "Allow devices to wake this computer" checkbox in the Advanced panel of the Bluetooth prefs. Try that and see if that works for you. Others on these boards have tried this and it has worked for them too.

    Guys

    I've worked around it by checking the "Allow devices to wake this computer" checkbox in the Advanced panel of the Bluetooth prefs.

    It works...

    Thanks to "gtmagnet" for the post...

    I have same problem on restart. My iMac keyboard works fine from sleep, but when I restart, I get a message that there is no keyboard connected, and it searches for the keyboard. It won't find it unless I actually hit a key on the keyboard, and then it finds it.

     

    I have 'allow devices to wake computer' already set.

     

    Magic Trackpad works fine

    chip, in your case "allow devices to wake computer" will not help, that is something different. Across a restart the keyboard gets disconnected and then reconnected, although for some reason for you the (auto)connection is failing. you might try re-pairing it in that case, although you should not need to. before you do, when you open the system prefs -> Bluetooth panel, and drag over the split pane divider, from the gear select "Show more info", and then tell me what the Major/Minor class values are. also, does it indicate it is paired, configured, both or ?

    Thanks. I assume you mean gather this info before I restart and try to connect:

     

    Keyboard: Paired and Configured. Major: Peripheral (0x5), Minor: Keyboard (0x10)

     

    Trackpad: Paired and Configured. Major: Peripheral (0x5), Minor: Keyboard (0x25)

     

    I also noticed that Advanced has "Open Bluetooth Setup Assistant at Startup if no keyboard is detected" Not sure if that is new, but I this setup assistant is new.

    well, those look right. the option for opening the assistant at startup isn't new for Lion.

     

    do you happen to have dev tools installed? you could run some (deeper) Bluetooth debug tools if you did...

    I do have Xcode installed.

     

    FWIW, I ran permission repair in disk utility to try to solve another issue from another thread. Upon restart, I was not challenged with the Keyboard Setup.  Not sure if this is related, but so far, the issue hasn't returned

    Trashing the preferences file didn't quite fix things afterall. It fixed it for the keyboard but not the mouse. The mouse kept dropping connections every few minutes.

     

    Needed to disable the mouse in Bluetooth preference pane. Delete it completely from the list, then add it in again (made it a favourite but not sure if this is important or not). So far on day two of no dropped connections.
