Subject: Failed to obtain handles for "Service Changed" characteristic, etc.

Hi,

I'm trying to use git bluetoothd in Ubuntu. When I start it I get the
following errors:

root@qountdown:~/src/bluez/src# ./bluetoothd -En
bluetoothd[23921]: Bluetooth daemon 5.37
bluetoothd[23921]: Starting SDP server
bluetoothd[23921]: Bluetooth management interface 1.6 initialized
bluetoothd[23921]: Failed to obtain handles for "Service Changed" characteristic
bluetoothd[23921]: Not enough free handles to register service
bluetoothd[23921]: Error adding Link Loss service
bluetoothd[23921]: Not enough free handles to register service

bluetoothd[23921]: Not enough free handles to register service
bluetoothd[23921]: Current Time Service could not be registered
bluetoothd[23921]: gatt-time-server: Input/output error (5)
bluetoothd[23921]: Not enough free handles to register service

bluetoothd[23921]: Failed to read advertising features: Unknown Command (0x01)
bluetoothd[23921]: hci0 Load Connection Parameters failed: Unknown
Command (0x01)

Where should I look to diagnose these?

These are plugins using deprecated API, we should be disable/removing
them in favor or external support via GATT D-Bus APIs.

These are more serious, it seems your kernel is too old and does not
support the command above which are quite important if you plan to
support peripheral role.
