5.2.4 Application Data Transmission with Periodic Indirect Data Request

This section describes the power profile of the Mi-Wi P2P sleeping device during the transmission of application data and the periodic data request. In the application firmware, press the external button to trigger the application data transmission. In the case of a power profile, unicast or broadcast data transmission is similar, as the payload size for both transmissions is the same. The application payload size during this measurement is the maximum possible payload size (76 bytes).
