Hello,

I'd like to create a client-server application in which a linux box (running bluez) will advertise a service by declaring a specific service uuid. the service needs to only be capable of sending / receiving strings so i'm assuming declaring a btspp service should be enough. that specific uuid will be embedded into a j2me midlet running on nokia 6600 (implementing jsr-82). the midlet will then search for service using url of format:

"btspp://1234567890123456789012" (uuid *has* to be chars long - nokia's apparent implementation limitation). so (correct me if i'm wrong )what i need is:
1.add Serial Port service via "sdptool add SP"
2.set attributeID 0x0003 (ServiceID) for the above Service Record to "1234567890123456789012"

correct?
i'm not sure of the sdptool syntax for step 2.

problem:
1.when i do step 1, i get "Serial Port registered". but, if i issue "sdptool get SP" afterwards, i get description of "SDP Server" (0x1000). shouldn't it return something like "SerialPort" (0x1101) - service class id for SerialPort per bt spec?
note: actually even if i issue "sdptool add LAN", subsequent "sdptool get LAN" returns same description as above.

2. also, i couldn't figure out exact syntax to accomplish step 2 above (set attribute):
sdptool setattr --help returns

"usage: sdptool get rec_handle attrib_id attrib_value", which seems not to be what i need to do...

thanks

so (correct me if i'm wrong )what i need is:
1.add Serial Port service via "sdptool add SP"
2.set attributeID 0x0003 (ServiceID) for the above Service Record to "1234567890123456789012"
correct?

I am not familiar with Symbian phones or JSR-82, so I can't help here.

I prefer you read the manpage of sdptool. The get command needs the record handle of the previous created record.

sdptool setattr --help returns
"usage: sdptool get rec_handle attrib_id attrib_value", which seems not to be what i need to do...

Again. Look at the manpage.

"man sdptool" returns nothing. the only thing i can look at is "sdptool --help". if that's not what you were referring to, where is sdptool's manpage?
%sdptool add --help
add [--channel] service

come on, check you MANPATH or look at the CVS
