Our project has been working on nRF21540 & nRF52833.
Let us have a method to reduce the power of nRF21540 under 400uA at idle.
Currently, without nRF21540, the power consumption was 50uA at idle status we achieved.
But with nRF21540(+nRF52833), the power consumption was 400uA at idle, nor more down under 400uA whatever we did.
The status is as follows;
1. 1mA consumption as soon as the turn on
2. and then the module was connected, back to disconnetion. 400uA was checked at idle.
