I'm using [nRF52_SDK_0.9.2] and original module. As a tool, I use the keil.
"NRF_POWER-> SYSTEMOFF = 1;" in the SDK example hrs also written, does not enter the system off mode (current value does not decrease).Written location is "main.c". and I add it after; "conn_params_init ()".
By the way, when you insert it into the "blinky" enter the system off mode (down the current value)
Why not enter the system off mode "hrs"?
The power instance is restricted when the SoftDevice is enabled, see this for more information.
This should be used instead.
I am replaced by "NRF_POWER-> SYSTEMOFF = 1" to “sd_power_system_off()” ,but do not enter system off mode (current value does not decrease).
Is it possible to enter the system off mode in Hrs?
It is possible. What kind of current numbers are you getting? Also, have a look at this question, it might be of help.
I am getting 4.42mA. Thank you for your proposal. I start reading immediately
Enter the system off mode when use the [nRF5_SDK_11.0.0] instead of [nRF52_SDK_0.9.2].
Thank you very much !
