2.2.3 LAUNCHXLCC1352R1 Communication

A LAUNCHXLCC1352R1 wireless MCU LaunchPad™ Development Kit is used as BLE or sub-1 GHz client, to receive the radar result data from the CC1352R device on the base board. Then, the LAUNCHXLCC1352R1 sends the data to a PC or cell phone GUI by using a virtual UART port (the user UART COM port number can be different on a different PC).

GUID-20231101-SS0I-DNNF-3LLP-QCDH87PKK9GT-low.png Figure 2-2 Virtual UART Port on PC or Phone GUI

The virtual UART port baud rate is set to "1250000".

This virtual UART port is also used to send the configurations to the IWRL6432 device on the base board.

Is this design, a simple serial socket client BLE application example is implemented in the LAUNCHXLCC1352R1.
