Using the LF Wake-Up Mode With UHF Response

Using the LF Wake-Up Mode With UHF Response

The following steps show how to enable complete (bidirectional) LF communication, which means that the
MRD2 can send an LF wake pattern and can then receive the UHF response of the RF430F5978EVM
module that receives the wake-up signal (see

Figure 10

).

1. Click "Wake up" button to start the wake-up sequence one time.

2. Click "Continuous wake up" to initiate continuous mode (approximately 2-s cycle time)

3. Click "Continuous wake up" again to stop the continuous mode.
