Hi, I am doing some experiments to understand Bluez DBUS API using Bluez 5.46, and feel a little bit confused about Gatt Dbus example code and bluetoothctl. First, I do sudo bluetoothd --experimental -d, then I create two virtual bt interfaces and bring up example-gatt-server, then example-gatt-client cannot find any new gatt service. Any idea? Also, I have checked all information under org.bluez using d-feet, the gatt service and characteristics from example-gatt-client have not yet been added. I print all infos under ObjectManager for bluez, and cannot find these services and characteristics. I also try to use register-service, and register-characteristic for hci0 using bluetoothctl, but I cannot find any added service and characteristics under d-feet and ObjectManager. Any idea? bluez-5.46$ sudo ./emulator/btvirt -L -l2 Bluetooth emulator ver 5.46 bluez-5.46/test$ sudo ./example-gatt-server Registering GATT application...
