ESP32 Wifi

Postby lebc08 » Wed Feb 16, 2022 9:19 am

How do I connect my ESP32 to wifi, without connecting the module to my computer? I plan to power it up with batteries

Depends on what firmware you program in it... connecting to WiFi is handled there, so you can do that in whatever way you want depending on how ypu program that firmware.

Currently I can connect my esp32 to wifi when I connect it to my computer but when I powered it up with battery, it will not connect. So this means that it’s programmed wrongly ?

Ah, like that. What 'battery' do you use, and which ESP32 devboard? Does pushing 'reset' get the ESP32 back to life?

I’m using a 3.7V 2500mAh Lithium ion battery on the ESP32 WROOM but I did not try the reset button because the esp32 was able to be powered up

I don't think that board is able to run directly off the 3.7V... if you connect it to the Vin input, the LDO doesn't have enough headroom to correctly regulate and the 3.7V is out-of-spec for the 3.3V input, so you can't connect it there either.
