get_reset_reason

To get the reason for the restart, I called the sd_power_reset_reason_get () function after the ble_stack_init () function in main, but there was a problem.The return value of this function is 0, but no matter how it is restarted, the value it gives is 0.

Hi,

Did you check the output parameter and not the actual return value (NRF_SUCCESS==0)?

uint32_t err_code

uint32_t reset_reason;

err_code  = sd_power_reset_reason_get(&reset_reason);

APP_ERROR_CHECK(err_code);

NRF_LOG_INFO("Reset reason: %d", reset_reason);

Here's what I wrote: 

uint32_t reason = 0, err_code = 0;
err_code = sd_power_reset_reason_get(&reason);
LOG("\r\nerr_code = %d, Reset = %d\r\n", err_code, reason);

The return value err_code is 0, and then the reason for that restart whatever the restart is, the get value is also 0.

Hi,

I see nothing wrong with the code you use. Do you have a bootloader or some other code that runs before this that may possibly clear the RESETREAS register?
