Hi,

We are using CC2650F128RGZT as development environment.

I am having following questions:

What is the use of POWER_SAVING ?

what is Power_setConstraint?

Hi,

If you are referencing to the defined symbol POWER_SAVING, this symbol is used for some conditional compilation in TI examples. In some of them, if the symbol POWER_SAVING is defined then the device cannot go in sleep mode. I would advice you to do a simple research in the code of your specific example to see where this symbol is used.

Regarding the function Power_setConstraint, it allows the developer to set constraints to power or not a given power domain during standby, power down and idle modes. You can consult the Power Management User's guide for further details. With that said, I would like to underline that this function is not supposed to be used at the application's level (only at the TI drivers' level).

I hope this will help,

Regards,

Hi,

POWER_SAVING is used to perform conditional compilation of your example.

- If the symbol is *not* defined then the device is not allowed to go in standby or power down modes. This configuration facilitates debugging.

- If the symbol is defined then the device can go in standby or power down modes to save energy. The Power driver will handle this.

I hope this will help,

Hi Ankita,

As your question were not related to the first topic of this thread, I have moved it to a second thread: https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/855568

If the current thread is resolved, please mark it as it :)

Thanks and regards,
