hi, Marcel

I am using arm-linux 2.4.27-vsr1 from atmel, and libs&utils I am using the 
latest 2.17 version. The kernel version is hard to change. I just think 
hcidump should also report the command status after inquire suceed. And 
since from the hcidump output, the inquire has already suceeded, the hcitool 
output should print the inquire result, but not"Inquiry failed.: Connection 
timed out".

Below is more information: 
1. I tried "hcitool inq", "hcitool scan", sdptool and l2ping, only l2ping 
outputs correctly.
2. If I don't run hcidump, my Nokia 7650 can connect to the arm box via 
Serial Profile every two times, but if I run hcidump, it can never connect 
succefully.
3. Among two data sendings from Nokia to arm box, one succeed, one failed 
(no data output from hcidump)
4. After about 5 times data sending from arm box to Nokia, it does not send 
back data to Nokia any more, and also at that time no more output from 
hcidump.

Everything seems to work perfectly between my linux PC and Nokia 7650.

Could you please give me more infomation for my next hacking? Thanks a lot!

If you need any information, please let me know. Looking forward to your 
reply!

Regards,
Andy
