ST25R3916B low power mode example

Hi everyone,

I'd like to use the ST25R3916B device for a very low-power device. I downloaded the X-CUBE-NFC6 library version 3.0.0, and I don't see an example of calling rfalLowPowerModeStart().

I saw earlier that someone managed to find it in version 1.0.0, but I can't find it anywhere.

Could someone help me? Or provide the library in this version, or an example of using this function in the latest version?

By the way: Why isn't this functionality included in the current examples? I think it's a very useful feature.

Best regards to everyone :)

Hi,

not sure what you want to achieve using rfalLowPowerModeStart(). It will put the device into a low power state not reacting to any events on the NFC antenna. The function is there, you can use it e.g. after having stopped the discovery (rfalNfcDeactivate(RFAL_NFC_DEACTIVATE_IDLE)).
