Hi every one,
I just finished PCB depended on this tutorial of this website (link below) and i have some problem with using gpio 9 and 10 as output in ESP12E. When i set gpio 9 as output, my esp12e always wdt reset per second, and when i do that with gpio 10 it is always HIGH state. But i see everything in the tutorial works so good -.- i cant understand what happening while many topics on gg told that IMPOSSIBLE to use both of them as I/O (especially gpio 9). Can you give me the solutions for this? Thanks for advance.

So... this tutorial is a scam??? Badly i have finished my pcb based on it -.- maybe i have to change 9, 10 to TX RX pin instead :(( so disappoint :((
I think it is more of a mistake. if you ave already build the PCB you can always cut the PCB trace with a sharp knife and connect it to any other pin of the ESP
What ESP version you are using, can you provide an image of your ESP module.
I have already post img of my esp12e in this link. Please help me. Thank u so much :3

PermalinkIn a ESP 12-E module GPIO 9 and 10 will always give you wdt Reset because if you configure this pins it will interrupt the communication process in between the actual ESP chip and the EEPROM chip inside it, which is why youi will get a wdt reset.
