I have a project in which I have 2 battery powered ESP32s. I want them to sleep most of the time, so their wifi modems will be powered off during these periods. I need a good strategy to determine when to send the ESP NOW messages so that the receiver's modem will be ON. (either can send messages at anytime).
Since both have an RTC, I was thinking about setting a rendez-vous time every 1 or 2 minutes to power the modems at the same time and exchange data. I am not sure if this will work, and I wanted to know if anyone had a better strategy?
Thanks for your help!
