Hi Marcel!
    Sorry for that. Maybe I rephrase the question like this.
    Now, I'm still struggling about how to add sdp service profiles in my Linux PC. And the most important thing is to let my computer to act as headset so that T610 can connect to it. I know that to add the service, using add_headset function is the way. But I find that only using this function is not enough, and I also find that there is a command called "setattr" that sets or adds the attributes to SDP record. Then I wish to know that if the setattr command, or set_attrib function in sdptool.c is necessary. If so, in the setattr command, there are two parameters that I've to enter, attrib_id and attrib_value. I wish to know what are the corresponding values of these two parameters from the following after I've typed "sdptool get --tree <recordhandle>"?
Attribute Identifier : 0x0 - ServiceRecordHandle
  Integer : 0x10002
Attribute Identifier : 0x1 - ServiceClassIDList
  Data Sequence
    UUID16 : 0x1108 - Headset
    UUID16 : 0x1203 - GenericAudio
Attribute Identifier : 0x4 - ProtocolDescriptorList
  Data Sequence
    Data Sequence
      UUID16 : 0x0100 - L2CAP
    Data Sequence
      UUID16 : 0x0003 - RFCOMM
      Channel/Port (Integer) : 0x5
Attribute Identifier : 0x5 - BrowseGroupList
  Data Sequence
    UUID16 : 0x1002 - PublicBrowseGroup (SDP)
Attribute Identifier : 0x9 - BluetoothProfileDescriptorList
  Data Sequence
    Data Sequence
      UUID16 : 0x1108 - Headset
      Version (Integer) : 0x100
Attribute Identifier : 0x100
     Lastly, I wish to konw that if I can let my PC to act as headset for T610, after I've added the profile in it, is there any program needed to install in T610 so that it can connect to the PC?
     Hope that this can be clearer to you. Thank you very much.

I have no idea what you really wanna know. Try to rephrase your
question.

now I get what you want. In general adding SDP records with sdptool is
only for testing purpose. You should include you own code for it, like
we do for pand or dund. However if you think that the add_headset() in
sdptool misses an attribute then fix this and send in a patch for it.

Regards

Marcel

Re: [Bluez-users] adding sdp service record attributes

[Ka Kin Cheung]

[-- Attachment #1: Type: text/plain, Size: 1118 bytes --]

Hi all!
    I've coded myself about how to add SDP services
and its attributes. But everytime I reboot Linux, the
service record handle and attribute do not exist, so I
have to run my program every time so that the record
and attribute are set. Also, even though I added the
headset service in my PC, T610 still searched my PC as
computer, not headset instead. So, I wish to ask 3
questions:
1.Is there any extra thing I have to put so that the
service record and attributes are set in my PC
permanently and not being erased after reboot?
2.After I add the service record and attribute, I wish
to let T610 to search my PC as headset. So, is there
any extra thing that I have to put in my code?
3.Is it possible that to browse the services in T610,
and even other mobile devices, and then add the
service records and attributes automatically?
    Attached is my code that I've written referencing
to sdptool.c. Hope you can give me solution about it.
Thank you very much.
Michael

Hi Marcel!
    Thanks for your reply. But I wish to know that from the result I've put in the last email, which belong to attrib_id and attrib_value respectively? I just want to know about this and then I'll put the correspnding values in my program to add it.  You can find the result of "sdptool get --tree " from last email. Thank you very much.

now I get what you want. In general adding SDP records with sdptool is
only for testing purpose. You should include you own code for it, like
we do for pand or dund. However if you think that the add_headset() in
sdptool misses an attribute then fix this and send in a patch for it.

Regards

Marcel

I don't get it. The attribute id the UINT16 value with an optional
textual representation and the indent stuff under it are the attribute
values. You should read the SDP part of the specification.

[Bluez-users] adding sdp service record attributes

[Ka Kin Cheung]

[-- Attachment #1: Type: text/plain, Size: 1243 bytes --]

Hi all!
    I'm trying to add sdp service profile using sdptool, and I found one that is to add attribute to a SDP record. I wish to know that is that true? If so, I wish to know what the values should be put according to this command "sdptool get record_handle attrib_id attrib_value"? Here is the result when I typed "sdptool get --tree record_handle". I wish to know that what corresponds attrib_id and attrib_value?
    Thank you very much.
Michael

I have no idea what you really wanna know. Try to rephrase your
question.
