Sending ESP to deep sleep from another MCU
Posted: Sun Sep 10, 2017 11:06 am
What's the best way to save power on the ESP8266? I have a configuration where the ESP is connected to another MCU and will be used just to report data to a remote server.
I have 2 options here:
1) Let main MCU cut power to the ESP
2) Let main MCU ask ESP to go in deep sleep until main MCU wakes up the ESP
I am considering the fact in which the ESP hangs and doesn't listen to MCU commands anymore (they communicate via serial port)
