Re: ESP32 not waking up from deep sleep anymore

Is there a way to do some sort of self test to see if it's an hardware issue and maybe affects other parts as well? Maybe I shorted out something or it's because I used a very large capacitor to stabilize power supply during wifi begin as it tended to shut down during those events?

Re: ESP32 not waking up from deep sleep anymore

Just to make sure I used a fresh d1 mini module and it works fine with the regular drop sleep in demo and in my build, which is a 3AA battery powered tank level meter. I desoldered the inboard power led and it's now using about 1mA in regular deep sleep and it did wake up every 6 hours as I planned ...

Hi. I am currently still arduino IDE as I started with arduino before basically moving on to esp32. For testing and flashing I use a windows laptop with USB. To measure power draw I unplug it and give voltage via the vcc pin, as I want it to run on battery, I use 3AA batteries. Then I use an multime...

ESP32 not waking up from deep sleep anymore

Hello. I built a tank level sensor with the ESP32 (D1 mini board) and a TOF sensor. To have it run only once a day on low power, I used deep sleep with RTC timer wakeup function and RTC GPIO pins to trigger the low power mode of the TOF module. void startDeepSleep(){ delay(1000); //wait a moment bef...
