hi marcel and all,
I have the following doubts
1> I use "hcitool cc <bt_addr> command " to connect to my neighboring
BT device. The first few times this connects with no errors. After
sometime, the connection goes down for some reason and if I try yo
coonect again, I get an error saying
"Can't create connection: Input/output error"......can someone tell me
as to why i am getting this error.
2> I use bnep for tcp/ip communication and this connection also goes
down after sometime. I try to connect using "pand --connect
<bt_addr>"....and in /var/log/daemon.log in get the following lines
Nov 16 19:42:29 edpc449 pand[2128]: Bluetooth PAN daemon
Nov 16 19:42:29 edpc449 pand[2128]: Connecting to <bt_addr>
Nov 16 19:42:29 edpc449 pand[2128]: Connect to <bt_addr> failed.
Operation already in progress(114)
I have tried killing the processes and connection(using pand --kill)
on both sides....and then restarting them....but to no effect. Only a
clean reboot seems to be the solution.
Hope u can help me with this too.
regards,
manjunath

the RSSI, link quality and transmit power level commands of hcitool also
work when you created the connection through L2CAP etc. If you confuse
your Bluetooth chips with creation and termination of the low level HCI
connection then it is your fault.

Update to at least 2.6.9-mh3 or use 2.6.10-rc2.

the "hcitool cc ..." command is only for testing. Don't use it.
