I'm trying to connect my esp-01 to control my
air-conditioner.
When I start the ESP-01 I've LED and RED LEd always on.
I've connected:
CH_PD to 3.3V through 4.7K.
RESET to 3.3V through 4.7K.
GPIO0 is not connected.
GPIO2 is connected to a base of my transistor to control my IR LED.

Could you help me please! ....

I've added pull up(4.7K) but my esp doesn't work.
Do you know if 10K is really necessary?
