I have an MX5000 keyboard and I have paired it with my powerbook. While running PacketLogger.app, if I type the letter 'a' I get the following capture: [HIIr] HID Interrupt: [a1] Keyboard [01] Event Data [ 00 00 04 00 00 00 00 00 00 ] [HIIr] HID Interrupt: [a1] Keyboard [01] Event Data [ 00 00 00 00 00 00 00 00 00 ] but, no keystroke event shows up on screen. I have tried using one of the sample applications (hid_project) to add all the cookies to a queue to see if it is possible to see keystroke events with no luck. PacketLogger captures output for every button/key on the keyboard except the "sync" button which I assume is re-synching the keyboard with the laptop. Strange thing, some of the keys events do get through. The volume slider/mute buttons work out of the box, and I can make other buttons work by listening for the event in the hid_project sample code (ex, the digital button elementCookie is 0xf8 and the value is 440) I assumed it was a problem with the keyboard. I then had a friend try with another keyboard (I beleive it is an Apple Bluetooth keyboard but would have to confirm) and had him try packet logger with the letter 'a' as well and gets the same output. [HIIr] HID Interrupt: [a1] Keyboard [01] Event Data [ 00 00 04 00 00 00 00 00 00 ] [HIIr] HID Interrupt: [a1] Keyboard [01] Event Data [ 00 00 00 00 00 00 00 00 00 ] Am I missing something here? Is there something happening higher in the stack that is causing the MX5000 keyboard not to have events make it to the application? Any thoughts would be helpful. Thanks, Mike _______________________________________________ Do not post admin requests to the list. They will be ignored.

Bluetooth-dev mailing list (Bluetooth-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/bluetooth-dev/site_archiver%40lists.… I am not certain, but my guess is that it is all because of speed, the HID driver kext is designed to match on channel with PSM 0x11, which means that as soon as that channel shows up the kext will try to attach to it. Also an L2CAP channel (RFCOMM channels too) can have only one client. So the first client to connect wins. Simply openL2CAPChannelSync is faster than openL2CAPChannelAsync (since openL2CAPChannelAsync is a notification from kernel to user space) so with openL2CAPChannelSync you win with openL2CAPChannelAsync the kext wins. if I want to open a L2CAP connection to my MightyMouse on channel 0x11, it works if I call openL2CAPChannelSync however, if I try to open the same connection using openL2CAPChannelAsync (Async instead of Sync) my l2capChannelOpenComplete method of the listener gets called with an error. Can anyone explain why this happens ? The same seems to apply to Wii remote control devices and possibly all HDI devices.
