ESP8266 Community Forum

I am new to this board and I am having a few issues with an ESP-07 that i ordered off of Amazon
http://www.amazon.com/Diymall-Esp8266-S ... al_qh_dp_t

I have tried a few different baud rates using an Arduino Due (which is 3.3V on its tx/rx lines and gpio pins). I have tried having the ch_pd low or high, but when i tie it high at start the tx status led never blinks on the module itself(the power light is always on no matter what). I have tried gpio0,2 tied high/low and different combos and still nothing.

Any and all help will be greatly appreciated..

Some of us also had this problem. Take a look at here.

this post solved the problems of my 20+ modules. Probably this will solve your problems too

(BTW there is probably an AT firmware on your module so

GPIO15 + GND -> GND
CH_PD + 3.3v -> 3.3v
Tx -> Rx
Rx -> Tx

(if you are using your arduino without atmega328p on it as the serial adapter, Tx-Tx, Rx-Rx may do the trick )

GPIO0 -> GND will be required to download a new firmware, good luck, keep us informed on the thread i've sent

What you said with tying gpio 15 to gnd worked..... I had ch_pd tied either high or low and that would just output giberish this morning, but i removed that pin and BOOM it worked.... It says that i am running version 0.9.2.4 if that helps. THANKYOU!!!!!
