So, I tried your suggestions from within d-feet and made good progress, but I don't think I am quite there yet. Here is what I did inside d-feet: Under /org/bluez/hci0 -> Interfaces -> org.bluez.Adapter1 -> Methods -> StartDiscovery --> double clicked and 'executed' this Under /org/bluez/hci0/dev_XXXXX -> Interfaces -> org.bluez.Device1 -> Methods -> Connect --> double clicked and 'executed' this Under /org/bluez/hci0/dev_XXXX -> Interfaces -> org.freedesktop.DBus.Properties -> GetAll ---> double clicked, entered '"org.bluez.Device1"' and 'executed' this ---> received valid UUIDs, GattServices, etc as output Thank you! I did _not_ see GattCharacteristic1 in the output, nor do I see either GattService or GattCharacteristic1 show up as an interface in either /org/bluez/hci0/dev_XXXXX or /org/bluez/hci0. Did I miss a step or misunderstand your suggestion? Cheers, Don
