ESPTool 3-run stub fail error I'm trying to program my NodeMCU ESP8266 ESP-12E module with AT commands. However, whenever I try and flash to my ESP8266 using ESPTool, I get a 3-run stub fail error. Can anyone tell me why I get this error and how to fix it?
I have my suspicions that it might be the fact that I haven't pulled any of the pins, but I've been told that GPIO0, GPIO2, GPIO15, and CH_PD are all already pulled to the proper positions by default. If that may be the reason behind this error, could someone explain to me how exactly I should pull the pins, whether it be with a circuit or through code?
If it helps, I'm trying to follow along with this resource.
The only thing the ESP is connected to is the computer with USB.
Just wanted to update and let anyone who had a similar issue learn how I solved the problem.
My baud rate was set to 1152000 rather than 115200. Setting it to 115200 solved my problem.
