Re: [Bluez-users] adding a sdp service with a 128bit uuid

[Marco Trudel <mtrudel@gmx.ch>]

Hallo Michael

just read the sdptool.c... it's all there. basically you need
add_sp(sdp_session_t *session, svc_info_t *si)

respectively you told once something about headset, i think... there is a
method like add_headset()...

regards
Marco
