We are working with the nRF7002-DK board and need to measure and minimize power consumption.
We are using Wi-Fi in our application and currently working with the sample nrf/samples/wifi/shutdown.
During the shutdown phase, we measure an average current consumption of ~1mA on the nRF5340:
On the other hand, when running the blinky example with CONFIG_SERIAL=n, we are able to achieve a current consumption of 6µA, which is our target.
We were expecting similar results in the Wi-Fi shutdown example.
However, in the shutdown sample, we cannot set CONFIG_SERIAL=n, as this causes build errors: "FAILED: modules/nrf_wifi/bus/CMakeFiles/nrf70-buslib.dir/qspi_if.c.obj"
How can we properly reduce power consumption by fully shutting down the Wi-Fi module and reach our target when working with this example?
Thanks!
