Re: estimating battery life

Loboris,

Thanks for the fast reply.

That makes sense. Essentially I count the number of 10s wakeups before the battery goes dead and divide them by the number of expected wakeups per day (in my case 40) and I will get how many days the device should be operational.

Thanks.

WIFI lower power mode?

Hi,

When awake the esp-wroom-32 is running the soft AP.

Thanks!

OK. Thanks for the fast reply. Also is there a changelog between firmware updates? I updated the firmware from October (esp32-20181012) to the latest version (esp32-20180511) and noticed that the touchpad pin values have ~doubled for the same input. I put back the old firmware and got back the origi...

ESP32 documentation link

Hi,

Where can I find ESP32 Micropython documentation? Should I just look at ESP8266 and assume its the same for ESP32? What about esp32 specific methods?

Thanks!
