Problem!!! got problem in power management in nRF51

[Urvisha Andani]

Hello All,

I am working on nRF51822 using IAR IDE and nRF51 SDK 12.3.0.

Right now I am checking power consumption of device in ideal mode but right now it is higher.

I uploaded example of pwr given in peripheral folder and it works.

path: ..\..\sdk_12_3_0\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\pwr_mgmt

So i think using nrf_pwr_mgmt library I got low power consumption so I have implemented initialization of power management in my application as shown below.

int main()

{

.

.

        ret_code_t ret_code = nrf_pwr_mgmt_init(APP_TIMER_TICKS(1000, APP_TIMER_PRESCALER));
        APP_ERROR_CHECK(ret_code);

.

.

        for (;;)
        {
                 if (NRF_LOG_PROCESS() == false)
                {
                      nrf_pwr_mgmt_run();
                }

} 

Then upload program in my device but it not works.

in nrf_pwr_mgmt_run() this function SOFTDEVICE_PRESENT is not define. But in this function 

#ifdef SOFTDEVICE_PRESENT
ret_code_t ret_code = sd_app_evt_wait();
if (ret_code == NRF_ERROR_SOFTDEVICE_NOT_ENABLED)
{
__WFE();
__SEV();
__WFE();
}
else
{
APP_ERROR_CHECK(ret_code);
}
#else
__WFE();
__SEV();
__WFE();
#endif // SOFTDEVICE_PRESENT

this portion is not execute.

so please give me suggestion.

Thanks & regards,

Hi,

Have you remembered to flash the appropriate Softdevice to the board? The code block under #ifdef SOFTDEVICE_PRESENT should run if the softdevice is included.
