These sources are: Timer; Touch pad; External wakeup(ext0 & ext1) Wake-up sources can be combined, in this case the chip will wake up when any one of the sources is triggered. We’ll cover timer wake up and external wake up. Voltmeter, divider resistors values, I used E24 values from my kit, but it is offcourse easier with trimmers, GPIO16 can be used to wake up the ESP8266 from deep sleep. For example, when ESP8266EX sleeps for 300s then wakes up to connect to AP (taking about 0. So, when you call ESP. When I do that however I can't program the chip as the programmer uses RST and the thing just hangs. You can use this example as a boilerplate for other programs. Finish data acquisition 5. If you want that system should not wakeup (no wakeup until rst pin to low ) system_deep_sleep(0) ===== load Deep-sleep 4. esp8266 deep sleep wake up time
