Hi! In november I've bought 2 of those ESP-01 v2 modules from banggood, yesterday I received the package from China and I'm struggling to make them work with no luck. I've made the connections as I've found on the Internet, but nothing seems to work. I'm powering the module from 3.3V, I'm using a voltage divider with a 47K and a 100K resistors for RX pin of the module, but It doesn't seem to respond to AT Commands... I've tried to flash a new firmware using Viktor's method, but it gives me Failed to connect. As a programmer I've used Arduino UNO, but it doesn't receive anything on the serial monitor and now I'm using a CP2102 but it only receive this:


,and is doing nothing.

I've managed to connect to the module using my smartphone, even with my laptop, but this doesn't help me too much. Can anyone help me with this? Please!! Thanks!

You have iot firmware and you must flash at firmware for at command set.

Thanks for the fast reply! How should I do that? Can you give me a link to a tutorial or something?

I am mobile now. But you can search in site.
