About sd_power_system_off

[Elliot.Chao]

Hi,

I use ble_ant_app_hrm example on 41822.

I set advertising time is 10 secs then I will get a timeout event from stack. When I get this timeout event, I will put the system into off mode with sd_power_system_off API, I think that I can see few uA current.

But when I call sd_power_system_off API, the system will auto reset. I can not stay system poer off mode. Why???

Thank you.

int main(void) { uint32_t err_code;

// Initialize S310 SoftDevice
ble_ant_stack_init();

err_code = sd_power_system_off();
APP_ERROR_CHECK(err_code);

// Enter main loop.
for (;;)
{
    power_manage();
}

}

I write a sample with only main() function. When I call stack init then system off. After stack init, the current will 1.35mA, but when I call sd_power_off function, the current will back to 4.5mA, Why????????

I use 51422 EVK board.
