Can send AT+ commands, but can't upload sketch
Posted: Mon Sep 28, 2015 11:08 amI'm using a generic ESP8266 module.
At the moment, I have a ESP8266 connected to an Arduino Uno through a 3.3V regulator, GPIO0 and GPIO2 are unused. I can send ANY AT command through the serial monitor of the Arduino Uno perfectly fine, and obtain a normal reply. However, when I attempt to upload any code at all, I get
I've tried just about everything I could find on this topic - connecting GPIO0 to ground, connecting GPIO0 and GPIO02 both to Vcc, switching Rx with Tx etc. to no avail.
Any ideas?
