nRF5340 in nRF7002DK consumes high current in idle state

[seongbin]

Hello,

I am testing on nRF7002DK board using nrf/samples/wifi/ble_coex sample.

The sample is working fine and I am measuring current consumption of nRF5340 and nRF7002 using two PPK2.

After coexistence test is finished, nRF5340 is not doing anything but consuming 5mA current on average.

Is it normal for nRF5340 to consume 5mA current on average when it is not doing anything?

I applied the guide below to reduce current consumption but got the same result.

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/test_and_optimize/optimizing/power_general.html

Could you please help me with this issue?

 

Regards,

After coexistence test is finished, the nRF5340 current consumption is 5mA on average and the nRF7002 current consumption is 17uA on average.
