3.1.1 Initialization

This section captures the power consumption of the WLR089 device during the initialization and highlights the profile corresponding to different initialization events. The following plots in this section illustrate the zoomed-in plot of different initialization events.

The following figure illustrates the zoomed-in plot driver initialization instance.

The following are the initialization events:

  • EVENT – A is a driver initialization event to initialize the radio, SW timer, persistent data server and Advanced Encryption Standard (AES) modules.
  • EVENT – B is a stack initialization and SW timer creation event.
  • EVENT – C is an application and LoRaWAN initialization event.
