Yeah.. the problem is that only certain types of symbols are exported to external plugins by bluetoothd (check src/bluetooth.ver). And sdp_* are not among them. (TBH I'm not sure why I didn't noticed this when running bluetoothd from source tree). I think we would have to provide SDP record as xml and then only generate sdp_data in Bluetooth input code. Other solution would be to export sdp_* symbols (if those are the only ones that are missing). Unfortunately I'm quite busy recently and cannot provide any ETA for those changes. But if you want to pick this up, I'll be able to review patches (you are not the first person asking for this). > > gardenia:/root # /usr/lib/bluetooth/bluetoothd -n -d 9 > bluetoothd[5943]: Bluetooth daemon 5.37 > bluetoothd[5943]: Starting SDP server > bluetoothd[5943]: Can't load plugin > /usr/lib/bluetooth/plugins/sixaxis.so: > /usr/lib/bluetooth/plugins/sixaxis.so: undefined symbol: sdp_data_alloc > bluetoothd[5943]: Bluetooth management interface 1.6 initialized > -- pozdrawiam Szymon Janc
