[Bluez-users] Sniff traffic between PDA and Phone

[nick-bluez@nickpiper.co.uk]

Hi,

I'm trying to capture bluetooth traffic between my PDA and mobile
phone for diagnostic purposes:

I have a Palm TX PDA and Samsung Z500 phone. If I try to use GRPS over
bluetooth (actually 3G, but it works the same) ppp connects and I am
given an IP address and DNS servers. If I try to send any traffic, the
packets are not sent. I can't ping the DNS servers for example.

If I change the phone for a different brand then it works fine, and if
I change the PDA for a different model it works fine. Just those two
together don't work. I've borrowed a different Z500 just in case mine
was faulty, but the same problem. The other one had a slightly newer
ROM too so this isn't something they have fixed.

I'm trying to find out if it is my phone or PDA that is a
problem. Right now, Samsung blames Palm, and Palm blames Samsung. My
carrier (Orange) blames them both, and would charge me a lot of money
to change phone :-(

I hoped that I could use hcidump to see if the Palm TX actually sends
packets, and if so, to compare them with what the Palm T3 sends. Can
I tell hcidump and my Bluetooth dongle to capture ALL traffic, not
just traffic going to/from the dongle?

I have a MSI dongle. It looks like this:
http://www.msi.com.tw/program/products/communication/cmu/pro_cmu_detail.php?UID=326

I am using Debian, kernel 2.6.15. 

ii  bluez-hcidump                      1.28-1 
ii  bluez-pin                          0.30-2  
ii  bluez-utils                        2.24-2  

Thank you,

 Nick
