Software

The software on the TI-RSLK LaunchPad development kit is a modified version of the rfEchoTx project example that is in version 3.40.00.02 of the SimpleLinkā„¢ CC13x2 26x2 SDK. Similarly, the PC LaunchPad uses the rfEchoRx code example within the same SDK. Both of these code examples are within the Software/SimpleLink CC13x2 C26x2 SDK v:3.40.00.02/Examples/ TI Drivers folder of the SimpleLink CC13x2 26x2 SDK.

These two code examples set up bidirectional communication between the TI-RSLK LaunchPad and PC LaunchPad. The code examples were modified to use a packet interval of 0.3 seconds instead of the 1 second default. Besides this, the other radio settings have been reused from the code example. Figure 5-1 shows the timing of the packet transmission and reception at the TI-RSLK LaunchPad and the PC LaunchPad.
