After the hierarchy is established, the network starts synchronizing by exchanging synchronization messages between the components. There are five message types defined in PTP: Sync, Delay_Req, Follow_Up, Delay_Resp, Management. The basic sequence required to synchronize a slave clock to a master ...
If you only want to look at the services and characteristics Furby exposes via its BLE GATT hierarchy, you can look at those using node fluffd.js introspect Sending commands using fluffd-client Trivia Furby's mood Furby's emotional state can be defined as a vector of the following properties...
All following commands start in the same hierarchy as the previous command, if no leading ":" is given. This can greatly reduce the amount of data transmitted to the HV device. So the following two commands are identical: :MEAS:VOLT?;:MEAS:CURR? :MEAS:VOLT?;CURR? For request commands,...
