Hi, Is there a way, using ESP-NOW, for the slave/receiver to request the data from the master/sender? As opposed to the master just sending out data on some given interval? In this case the master will be battery operated and , of course, I'd like the battery to last for more than a year before repl...

Is there anyway to have the battery operated server (with the sensor data) to be in some LP mode and have the Client poll it ( or something) to wake it up, connect, make a data transfer, disconnect, go to sleep, repeat?

Thanks!
