This is the one you will see when you scan devices. a UUID for the service. Thunkable does not use it nor show it. a UUID to send data this is called characteristic UUID. This is required by Thunkable but unfortunately there is no way to scan it within Thunkable. a UUID to receive d… > [@Getting UUID of a BLE device in thunkable](https://community.thunkable.com/t/getting-uuid-of-a-ble-device-in-thunkable/1121188): > > Hi I’m a first time user of thunkable and want to make an app that connects to a bluetooth LE bicycle speed sensor. There are some helpful youtube tutorials that show how to connect but they all seem to use a different program to find the UUID. Is there anyway that you can use thunkable to scan the device to find it’s UUID and then use this to input the UUID so that my app can receive data from the BLE device. I want to have the app work with different speed sensors, not just the one I have.
