Low Power Mode not that low power

[Riaan]

Hi,

I want to enter the NRF52 into a standby low power mode.

I am running sdk17.0.2, with FreeRTOS and softdevice (7.2)

The steps I take are:

1) stop all my threads

2) Setup interrupt to bring out of sleep mode

3) sd_power_system_off();

I can see the current being drawn dip to around 2.5mA to 3mA, but I was hoping for less current.

Is there something else I got to do?

Have you tested your project on Nordic DK?  does it behave the same?

is it possible to attach your project so that i can do some quick tests on my desk?

Turn off UART. 2.5mA - 3mA seems like the kinda current UART would take when left on despite being in sleep mode.
