Hi,
This problem has been causing problems for quite some time now with numerous bluez and kernel version .
I'm using a bluetooth dongle to run a serial connection on top and the result is quite unstable: it can crash up to 10-20 times a day. The only work around is to unplug and replug the dongle (or reboot the system, sic). Hciconfig hci0 reset helps sometimes. I tried to reset the usb device and the entire bus without any success.
I caught the script outputting a couple of times:
Traceback (most recent call last):
File "/usr/local/ /serial.py", line 46, in <module>
charout = sock.recv(1)
File "<string>", line 5, in recv
bluetooth.btcommon.BluetoothError: (103, 'Software caused connection abort')
and hciconfig hci0 reset when the dongle is crashed returns Can't init device hci0: Connection timed out (110)
I noticed tonight that reception might have an influence (need to test further). Poor reception could be increasing the frequency of crashes: the signal have to cross 2 doors if they are closed.
hcitool lq <mac> gives me around 13-15 with open doors and 6-9 with doors closed:
BTW the problem looks worse with the current kernel and bluez version which I'm using
root@:/ # uname -a
Linux 2.6.38-voyage #1 SMP PREEMPT Fri Jun 24 01:46:28 GMT 2011 i586 GNU/Linux
root@:/ # dpkg -l | grep bluez
ii bluez 4.94-2 Bluetooth tools and daemons
ii bluez-utils 4.94-2 Transitional package
ii python-bluez 0.18-1+b2 Python wrappers around BlueZ for rapid bluetooth development
any ideas how to fix the problem or to troubleshoot?
cheers
Erik
