- Sat Sep 12, 2015 4:28 am #28894 Well, I am using FTDI to upload an Arduino program to esp12, wiring as https://raw.githubusercontent.com/esp82 ... serial.png
I think the problem lays in the wiring. Although I think this wiring for uploading is correct, I am not sure which way is correct when running it with FTDI as a receptor of URAT.

Well, the FTDI issue is a new problem that you didn't mentioned before. It doesn't help to try to narrow the issue.
Do you mean that you are using the Arduino to upload to Flash or you are using the FTDI ?
Do you have a common ground on all the setup ?

GPIO2 also need to be pulled up with a 10K resistor. Connect DTR to GPIO0 only when Upload needed.
