Wake up from sleep using Android App via bluetooth or wifi
Posted: Mon Sep 26, 2022 12:58 am
Hello,
I know that the BLE Stack make use of various interrupt sources, i.e. timers, clocks, BLE radio events.
So I'd like to know that is there way to wake up ESP32 from BLE or WiFi connection
I think that the BLE doesn't cause an instantaneous interrupt like a hardware interrupt from the ESP32
, but the device have to be periodically scanning for a wake up event.
But in my application, i need to wake the device from android app.
Is there a way to detect an RF signal using a chip or a simple circuit?
thanks
