if it is the same SDK as this one, then this thread has a solution, if it not then please create a new thread.

Ok thank you for help. I confirm the example is now working (going to sleep where consumes 2uA).

Hi, all SDK 13.0.0 have logging enabled by default, and current consumption will drop back to normal if you disable it in sdk_config.h. More information here: devzone.nordicsemi.com/.../

Hello Aryan, thanks for response. I did not know there was 13.0 already out. I looked into source codes and it seems someone try to fix it. But I just tried example sdk13.0_orig\examples\ble_peripheral\ble_app_hrs_freertos\pca10040\s132\arm5_no_packs\ble_app_hrs_freertos_pca10040_s132.uvprojx and it has huge power consumption 7mA. I connected detect pin to turn off led but still 7mA. Can you remeasure and let someone fix the demo? But just now I tried the other option to overwrite freertos folder from 13.0->12.1. After merging FreeRTOSConfig.h I confirm I have expected 2 uA. Thank you!!! :))) But pelase fix your SDK 13.0 free rtos example...

This has been fixed in 13.0.0. If you do not want to migrate to 13.0, then use freertos files from 13.0.0 and copy them to 12.2. You have to copy files from folder sdk/external/freertos
