hi, all

HCI command do not complete after "inquiure request" completed succesfully.

I run "hcitool inq" & "hcidum", the output is as following:

HCIDump - HCI packet analyzer ver 1.16
device: hci0 snap_len: 1028 filter: 0xffffffff
< HCI Command: Inquiry (0x01|0x0001) plen 5
33 8B 9E 08 00
> HCI Event: Command Status (0x0f) plen 4
00 01 01 04
> HCI Event: Inquiry Result (0x02) plen 15
01 91 DC AC EE 02 00 01 00 00 04 22 50 C5 57
> HCI Event: Inquiry Complete (0x01) plen 1
00

(based on the packet dump, the inquery is succesful, and hcid should 
complete), but hcitool output is:
Inquiring ...
Inquiry failed.: Connection timed out

Is it a HCID problem? How can I fix it? I thought it will also cause packet 
lost & program hang.

Regards,
Andy

what kernel and libs/utils are you using. And what do you think has hcid
to do with an inquiry?

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

hi, Marcel

More information coming... 

I dump the data at both PC & arm box when I connect from Nokia, it turns out 
that after request the Service Attribute, the PC side prints a connect 
request, but at arm side, it prints a disconnect request (with reason 0x13, 
user ended request), but obviously the Nokia does not send a disconnect 
request. the reasons are:

Before this request, all the other information are the same & correct: 
write link policy settings, change connection packet type, Service search 
request, service attribute requestion. for all these request, the bluez 
gives the correct response data (serial profile, channel 3).

Looking forward to your further information.

All the best,
Andy

I need an "hcidump -X -V" to understand what is going on.

Marcel

the command status is not allowed after the inquiry succeeded. Please
install the latest hcidump and run it with the "-X -V" parameters.

Your kernel is quite old and I am not going to debug it. Try to include
at least my -mh patch for the 2.4.27 kernel.

This is strange. Do you run your ARM CPU in big endian mode?

This actually can't be, because hcidump has no influence.

Very strange.

You might consider buying a Bluetooth sniffer.

Are you using the same kernel source as on your ARM platform?
