Hi Beike.

Using NRF_POWER->RAM[i].POWERCLR = 0x00030003 before you call ble_stack_init() should work fine.

Are you sure you did not use it after you call ble_stack_init(), because that does not work.

Hi Andreas. thanks for your answer.

I will test this tomorrow, cal pwr_init() after call ble_stack_init().

by the way, I use NRF_POWER->RAM[i].POWERCLR = 0x00030003 in stead of sd_power_ram_power_clr before call ble_stack_init(), it result the code jump into HardFault handler function and cant't download to 52840 anymore.

can you tell me why?

Hi Beike.

If you use APP_ERROR_CHECK() on your ret_code you can find out that this error is found in nrf_error.h on line 63.

#define NRF_ERROR_SOFTDEVICE_NOT_ENABLED (NRF_ERROR_BASE_NUM + 2) ///< SoftDevice has not been enabled

This is because you use the pwr_init(); function before you enable the SoftDevice in the ble_stack_init(); function.
