1 Introduction

Below are additional test cases demonstrating the design's low power consumption. In some cases build of material (BOM) and firmware changes are required.

Adding test cases:

  • Testing current in hibernate mode
  • Testing current in LPDS mode
  • Testing average current under Intermittently connecting mode (sending 100 data to server)
  • Testing average current under always connecting mode (sending 100 data to server)
  • Test key step time when startup (via universal asynchronous receiver/transmitter (UART) printing or signal of connector)
  • Evaluate performance of video and audio

Test case Features:

  • The system can be put in wakeup from both Hibernate and LPDS mode via general-purpose input/output (GPIO) or real-time clock (RTC).
  • The current in hibernate mode is around 20 µA/5 V.
  • The current in LPDS mode is around 120 µA/5 V.
  • Startup time from hibernate to full running is less than 500 ms.
  • Configurable interval time in intermittently connecting mode or always connecting mode
  • Configurable stream transferring of only video, video and audio, video and ring
