Can't communicate with esp8266
Posted: Thu Aug 20, 2015 6:43 am
Hi there,
I connected the esp8266 module to the computer via usb to rs232 cable.
I also gave a supply of 3.3V and connected the chip with the right connections (tx --> rx, rx---> tx, gnd --> gnd, vcc & gpio0 -->vcc)
I tried to send AT commands through putty (at 9600 baud rate) but I see a blank screen (I cant communicate with it).
I see red and blue led turning on constantly. What can be the problem ? the wiring is OK (checked it 10000 times)
thanks
