Had finally time to test the ESP01 board.
So the program starts when power goes on and all works when connected to computer with USB programmer module. When i connect 2AA batteries to Ground and VCC, the lights go on, but no e-mail is sent. Should i connect any other pins to Ground or VCC? No GPIO pins are used in program.

What You mean by EN? Is it the same as CH_PD?

4pcs 10k resistors from VCC to these pins?
