If I I don't have any OBEX servers running and I do "sdptool add OPUSH" I get the apropriate EIR update with the OPP UUID (0x1105) added to the list, but if I do a consecutive "sdptool add FTP" 0x1106 doesn't get added even though it should. Then when I do sdptool del for the OPP record the UUID doesn't get removed from the EIR data. So it seems some things still need fixing. Also, could you somehow try to avoid the multiple "Write Extended Inquiry Response" commands while bluetoothd is probing drivers for an adapter that entered the UP state? With the class of device this is done through adapter->cache_enable, so maybe some more generic system could be used for all HCI trafic related to probing drivers.
