Heltec Wireless Stick Lite V3 light sleep consumption

#1

Hi,

when starting Heltec Wireless Stick Lite V3 i get 4mA consumption in “light sleep”.

I’m using Platformio, starting LoRa module (Radiolib library) and then making it sleep an all.

It does not change and always get 4mA in light sleep. Should it go lower than this when light sleep?

#2

killing Serial (Serial.end()) got me into the 1.45mA consumption territory.
then pinMode(pinNumber, INPUT) on all unused got me a 0.1mA and a little more freed also.

it seems i won’t get any lower :confused:

ESP32 just isn’t the greatest for power consumption. ~1.3mA for lightsleep is very decent, I don’t think you’ll be able to go much lower, unless you switch to deepsleep. Otherwise you’d have to try the (admittedly more complex) nRF or STM platforms.
