KW36 low-power operation

[jictannu]

In frdmkw36_wireless_examples_bluetooth_hrs_freertos, I set cPWR_UsePowerDownMode to 1 in app_preinclude.h:

But in heart_rate_sensor.c:

It looks like cPWR_UsePowerDownMode is not 1. And I download it into my FRDM-KW36,  it start advertise.only when I press sw3. Why cPWR_UsePowerDownMode is not 1?

Hi,

Hope you are doing well. In the SDK, in the docs>wireless>Bluetooth folder, is the Bluetooth Low Energy Demo Applications User Guide. In the Chapter Five (Bluetooth LE Stack and Demo Applications), the section 5.1.3 mentions that the application default configuration enables low power, which disables LED support.

So if you import the Heart rate sensor demo example and do not modify it, the Low Power is enabled you will only need to follow those steps in order to make the demo work.

Hope this helps.

Regards,
