Hi all Can you give me a quick example with a pseudo code (or using qdbus) for workflow steps how to setup an auto connect to a device that supports given UUID service (0000180f-0000-1000-8000-00805f9b34fb - Battery Service) >From what I understand all I need to do is send a call to the sytembus to register the hci0 adapter to auto connect org.bluez.ProfileManager1.RegisterProfile , /org/bluez/Test (ObjPath), "00001802-0000-1000-8000-00805f9b34fb” (service UUID) and if the discovery finds a device with such service it should auto connect right ? I am not sure what is the ObjPath parameter for and when i introspect I don’t even see the /org/bluez/GattProfile1 I am using bluez Version 5.45 on a Raspberry Pi zero Linux 4.4.50+ armv6l I tried making the call using with gdbus, but couldn’t figure out how to structure the osa{sv} paramters also tried dbus-send , but the tool doesn’t seem to support this structures (no nesting) I am using golang godbus bindings and the call gets executed without an error , but the bluetooth adapter doesn’t auto connect here is the gist https://gist.githubusercontent.com/krasi-georgiev/56f88cd18893578fa83c328f038479d6/raw/25f11f2fd7b55d82590732fa8f253febda623645/main.go go get github.com/godbus/dbus wget https://gist.githubusercontent.com/krasi-georgiev/56f88cd18893578fa83c328f038479d6/raw/25f11f2fd7b55d82590732fa8f253febda623645/main.go go run main.go I would really appreciate some useful info.
