RF command to wake up micro and make it perform an action

Hello ST Community!

I am using the M24SR64-Y NFC front-end in my system where the microcontroller is always in a SLEEP state and it is woken up by a SendInterrupt from the Smartphone.
The microcontroller is used to perform weight measurements.

I would like to know if there is a specific RF command that not only allows me to wake up the micro, but also to make it perform an action.

The GPO is set as INT (0x40)

Could you give me some advice?

Thank you

    Hello

    Through the SendInterrupt command it is not possible to pass any other parameters that would give information on a specific action to be taken by the micro.

    One example of what that could be done is to dedicate one location into the EEPROM for the action to be taken by the micro. Write it prior to send the SendInterrupt, then read it from the micro.

    Hoping this helps.

    Regards
