Hello forum. I have a Heltec ESP32 LoRa board v2. I’ve read a lot on here that I can’t use Wifi and read the voltage from GPIO13 at the same time.
I need to use Wifi and also get the charging status of the battery in my application. I also read that the newer version of the board moved from pin 13 to 37 to get the battery charging status. I tried an example sketch with pin 37 and got 0 for the voltage. Pin 13 works fine but now I can’t use WiFi.
This is quite annoying. How are people doing a workaround to get the battery status and use WiFi at the same time?
