ESP8266 Community Forum

- Sat Nov 12, 2016 12:20 pm #58034 Hi,

I have flashed ESP8266 module with ESP Easy + Arduino IDE + USB FTDI. Seems it worked perfect, after that I could configure its setting also. But after few minutes I don't Know what happened but it stopped responding. Now whenever I plug to VCC GND with 3.3v it shows two light continuous (Bright RED and dim Blue) and its IP dont respond

Note: In my router I have assigned it with fixed IP

Please help. I am new to ESP8266 as well its forum. Shift this post to appropriate location if required

The dim blue led sounds like the led is getting a little power from a pull up resistor in the module. The red led I assume is a power led?

The ESP is a 3.3v device. Does the usb to serial converter have 3v or 5v on the rx and tx pins?

If the module is an ESP-07, ESP-12, or another one with more than four signal pins, make sure you have the required pull up resistors on GPIO-0 and GPIO-2, CHPD, and a pull down resistor on GPIO-15. Some modules have a pull up resistor on the reset line but some don't, so a pull up resistor there is probably required.
