ST25R3916 Power Down

Hi,

After executing rfalNfcInitialize() the consumption of my ST25R3916 it's about 6mA. How could I do to power down the device to achieve 0mA? I've tried with these functions with no success:

rfalSetAnalogConfig(RFAL_ANALOG_CONFIG_CHIP_DEINIT);

rfalDeinitialize();

Hi Ulysses,

I can see the rfalLowPowerModeStart() declaration in rfal_rf.h but I'm not able to find its implementation (rfal_rf.c ?).

I'm using rfal V2.0.10 from STM32CubeExpansion_NFC6_V1.0.0.

regards,

I've updated the STM32CubeExpansion_NFC6 to V1.1.0 and I've found the rfalLowPowerModeStart implementation.

Now the ST25R3916 low power mode works as expected.

Thank you!
