how can adjust to dozens of uA (with freertos)

[canan]

Chip: NRF52832; SDK: 13.0.0 Softdevice: s132_nrf52_5.0.0; Routines: ble_app_hrs_freertos; Configuration: Minimum system board, broadcast interval 1000ms; Question: Broadcast power consumption of about 800uA or so, power consumption is too high, how can adjust to dozens of uA (with freertos);

I presume you have ruled out things like the MCU being in debug mode and that the UART is not enabled etc ?

[canan]

That is the SDK routine, I only revised the broadcast interval, why SDK routines with freertos power so high?

[Roger Clark]

OK

Log is not enabled by default in that example, but I don't know if it uses the UART in some other way, probably not.

Did you power cycle the board after uploading

And what do you mean my "Minimum system board", do you mean custom design?

well if you have not configured the FreeRTOS to be in tickless idle mode, then it will consume more power because at the SDK default tick frequency, it will wake up the chip almost every millisecond. Use tickless idle as shown here

Built in tickless idle functionality is enabled by defining configUSE_TICKLESS_IDLE as 1 in FreeRTOSConfig.h

NOTE : there was a bug in tickless idle mode that made loose ticks.Apply the changes from my answer below in this case.

I also face this problem (around 800µA of current consumption), using FreeRTOS example on my custom board design (SDK 12.0.2 Softdevice s132 3.1.0, nRF52832 QFAAB0).

I removed any advertised BLE service, disabled NRF LOG module, applied the diff @Aryan just provided, and the FPU irq handler fix without success. My freeRTOSConfig file features :

#define configUSE_TICKLESS_IDLE 1
#define configUSE_TICKLESS_IDLE_SIMPLE_DEBUG 1
...
#define configUSE_IDLE_HOOK 1
#define configUSE_TICK_HOOK 0

I also tried another example without FreeRTOS (ble_app_template), my current consuption is brought down to around 30µA.

I off course detach the debugger and power cycle the board before testing current consumption.

Do you have any idea what's going on ?
