Hi,
I'm working on putting our system into low power idle mode. We use MyNewt to build our application. In order to get to the lowest power, I disabled BLE and all our drivers except UART for console and debug messages. We have a command that can shut off a bunch of stuff and call __WFE and __SEV(). The code is tested on a nrf52DK(PCA10040 1.2.4, 2018.23). I checked the current on P22 on the board and the measurement was 270uA @ 3.8V from external power supply. This is far away from what your data sheet described. I have checked the setting everywhere and can not figure out what else I need to turn off. Can you please provide some suggestion where I should check?
Thank you,
