Hi guys,

I´m new to the ESP modules and for about a few days I was trying to upload code to an esp-07 module. I used the Arduino IDE and an Arduino Nano as a programmer. I could finally upload code and it´s working, but now I wonder how to get the esp-07 to run without the nano. Right now, after removing the CH-PD Pin from VCC and PIN 15 from Ground it stops working. Actually I thought I will only need VCC and GND connected to the esp-07 module to make it run, am I wrong? This is my actual setup for programming the device and I would like to remove all connection but VCC and GND:

For normal Execution mode, you still need to have CH_PD pulled-up to VCC as well as RES and GPIO0/GPIO2 and GPIO15 still need to be pulled-down to GND.

...and to be more clear: pulled-down by resistors, not directly to GND.
