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 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 ?
