The LP-EM-CC2340R53 is preprogrammed with the Data Stream Application software that allows wireless communication with smartphones and tablets over Bluetooth Low Energy. Simply connect the LP-EM-CC2340R53 to the XDS110 Debug Probe and then to a computer or power supply.

When power is applied, the board will run a power-on self-test and the green LED will be lit.

To test the functionality of the Data Stream Application, download the Simplelink Connect application from one of the two App Stores below:

Apple App StoreGoogle Play Store
LP-EM-CC2340R53
LP-EM-CC2340R53

This app lets you control and visualize the Data Stream demo software running on the LaunchPad. An example of the Data stream Application is shown in Figure 4-1.

The Data Stream Application status information can also be seen on the UART port of the host PC as show in Figure 4-2.

Important: Clear your phone or tablet’s Bluetooth cache before running the application or when changing the application on the CC2340R53. If this step is not performed, then you may not see the available characteristics in the smartphone app. Note that closing the smartphone app or rebooting your phone does NOT clear the Bluetooth cache.

iOS: This is accomplished by toggling Bluetooth Off then On via either Settings → Bluetooth menu or the Control Center (Bluetooth icon)

Android: The procedure can vary by make, model, and software version. On recent versions, navigate to Settings → Apps Scroll over to All → Choose Bluetooth Share and tap on Clear Cache.
