Wake from DeepSleep with button? #9

Closed svenove closed 5 years ago

svenove commented 6 years ago

Is there any way to wake Badgy up by using the switch, when using ESP.deepSleep()? Like if I want the HourlyQuote-example to also update when I press the button. :)

Hi @svenove! Unfortunately no, the ESP8266 does not support GPIO interrupts to wake from deepsleep. The only way to wake the ESP8266 is to perform a power cycle (e.g. slide the power switch up and down) or by pulling the reset pin low.

@sqfmi That’s what I thought, hmm... What battery life can be expected when always awake? Like in the Spotify-example. I would expect that not using deepsleep has a huge impact on battery life?

Would be great if you could break out the reset pin or have pads that a momentary switch could be soldered on to.

In the meantime you could add your own push switch to the reset pin with a bit of careful soldering. and mount the switch on whatever you are housing the badgy in.

I guess calling wifi.stop() would reduce power consumption? At least if not reconnecting too often (as reconnect probably uses a bit more than keeping connected?).

So instead of deep sleep, I could disconnect from WiFi instead?

Any other tips for reducing power consumption? :)

Instead of deep sleep, you could also try "light sleep" mode which still allows you to wake on interrupt, and consumes ~1mA (according to documentation. Check out this thread for some code snippets and details: https://github.com/esp8266/Arduino/issues/1381
