NEW! App tools for ESP8266, Easy to upload code from Android to ESP8266 over WiFi (OTA) or USB (OTG).

How does this work? I can’t seem to get a connection. (No usb error)

What error did you get?

Ensure your phone support USB OTG, use good quality USB&OTG cable/adapter.

I get a "no usb connected " error.

And yes, my phone supports usb-otg like every device does. The last time i saw a device that did not support otg was 15 years ago
