Hello, the UUID stands for Universally Unique Identifier. You can use in your code the one from the shipping example, if you want to learn more visit this page. About the two write blocks…the first one configures the amount of data to be send and the second one sends the data. For your application you need on both VIs a Bluetooth server and a client to keep the communication back and forth, just use different channels and trigger the events once you get the data. Good luck!
