ESP8266 Community Forum

I have ESP8266 connected to my PC over FTD1232 module. ESP8266 is successfully flashed within MCUFlasher. After that GPI02 node is disconnected from GND.

When I want to connect it to ESPlorer, it wan't to work. Just got the message "communication with mcu..", and nothing happend.

The same thing is happening with LuaLoader - I can open COM port and that's it.

I tried this with two ESP8266 modules, but both are doing the same...

What I'm doing wrong?

After that GPI02 node is disconnected from GND.

Why is connected to GND? Perhaps GPIO0?
Set COM speed to 115.2kbd!

I have ESP12e that I program with esplorer. It works always but I had some difficulties getting going. Here is how they are wired now:
GPIO0 pulled up to Vcc, grounded to flash
GPIO2 pulled up to Vcc
GPIO15 tied to Grd (if I recall I had no comm with esplorer until I did that)
CH_PD tied to Vcc
Hope that this helps, Good luck.
