Hi,
Background:
- We're developing wireless application with the NRF5340-NRF7002 chipset, similar to what's on the 7002DK board.
- We'd like to put the system to lowest power mode when it's not being used.
- I found two samples related to this: nrf/samples/wifi/shutdown and zephyr/samples/boards/nrf/system_off
My questions are:
- Which sample shall I base my project on?
- The wifi/shutdown sample page states that "This also demonstrates how to achieve the lowest possible power consumption in the Host SoC (nRF53, nRF52 or nRF91 Series) when Wi-Fi is enabled but not being used." - How is this achieved? I can only see function net_if_down() is used. I assume this will only turn off the nRF7002 wifi chip, but not the host?
- The system_off sample uses sys_poweroff() function, will this shut down both nRF5340 and nRF7002 chips? What happens when BT and/or Wifi are being used?
Many thanks in advance!
