while hcitool & sdptool operate, code fail connecting sdp errno == 2 ( enoent ), following failing code:

m_psdpsession = sdp_connect(bdaddr_any, bdaddr_local, sdp_retry_if_busy | sdp_wait_on_close);

why 'sdp_connect' failing? how can have resolved ?

edit /usr/lib/systemd/system/bluetooth.service , includ flag in execstart option.
