I'm unable to communicate with my Intel WP chip via HCI User channel. To test user channel, I use bluemoon: $ hciconfig hci0 down $ bluemoon -i hci0 Bluemoon configuration utility ver 5.30 Then bluemoon hangs up, no HCI event... HCI packet seems successfully sent, but no HCI response: [ 491.525914] Bluetooth: hci0 [ 491.525918] Bluetooth: hci0 [ 491.525924] Bluetooth: hci0 [ 491.525927] Bluetooth: hci0 [ 491.525964] Bluetooth: hci0 [ 491.526114] Bluetooth: hci0 urb ffff8800c1f320c0 status 0 count 3 When I kill bluemoon, I get same kind of issue (cmd timeout): [ 895.603661] Bluetooth: hci0 urb ffff8802f89d5b40 status 0 count 3 [ 897.606323] Bluetooth: hci0 command 0xfc3f tx timeout [ 897.606350] Bluetooth: hci0 [ 897.607011] Bluetooth: hci0 urb ffff88030c2c83c0 status 0 count 244 [ 899.612007] Bluetooth: hci0 command 0x0c52 tx timeout After that, device still usable by other sockets (hciconfig, hcitool...) I wonder if you reproduce this issue on your side? Regards, Loic -- Intel Open Source Technology Center http://oss.intel.com/
