Subject: bluetooth-next HCI user channel issue
Date: Mon, 20 Apr 2015 12:35:13 +0200 [thread overview]

Hi Marcel,
Seems there is a regression in bluetooth-next.
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
