Hi *, despite the ReadValue Documentation: Methods array{byte} ReadValue(dict options) Issues a request to read the value of the characteristic and returns the value if the operation was successful. Possible options: "offset": uint16 offset "device": Object Device (Server only) We don’t get the offset value, but only the device entry: Keyhandling.ReadValue(), options={'device': '/org/bluez/hci0/dev_45_4A_B8_B8_BA_09'} We are running Bluez 5.47 on Debian Stretch on armv7l. What have we done wrong?
