Re: [Bluez-devel] SDP problem with some Sony Ericsson phones.

Hi,

Thank you for your answer :o)

No, I only wanted to connect the K800i to my access point as I have heard it has PANU support 
but I guess that is wrong. Should I still however not be able to discover the NAP service on the 
access point or? Thanks once again.

Kind Regards,

Jeppe F.

Hello,

what are you trying to achive? Connect K710i and K800i to PAN access 
point and use its network resources? That won't work, as they lack 
PANU - client side of PAN profile. The K series only has NAP side 
implemented, whit which they only share Packed Switched data to one 
client - e.g. your computer. The SE smarpthones, namely P990i, M600i and 
W950i all have full PAN profile support, they can be either GN, NAP or 
PANU.

Hi,

I have a SDP problem with some Sony Ericsson phones (e.g. K710i and K800i) on my home made bluetooth access point running bluez-libs-2.25 and bluez-utils-2.25. My W950i phone (running Symbian UIQ3) and my computer (Windows 2000) with a Hama bluetooth USB dongle works perfect and I am able to discover the NAP service on the access point (see the hcidump below) and connect to it. 

When I i.e. pair a K800i phone with the access point and afterwards try to list the services the phone says that no services are found. I can however see that the K800i phone (see the hcidump further down) is using another way of discovering services which could be the problem. But it actually looks like the access point is answering back to the phone with a SDP SSA response.  

Is this a problem in the SDP part of bluez or is it something in the Sony Ericsson phones? If it is a bluez problem does anyone know how to solve this issue?

Thank you very much for the help :o)


Kind Regards,

Jeppe F.
