Just connect CH_PD (pin 4 on ESP-01) to a GPIO of your Arduino, this way you can completely disable the ESP by pulling the GPIO low.

Thanks a lot !
I have tested your solution and it's what I need

- Mon Mar 23, 2015 9:04 am #12480 Hello: I have a Nano/ESP8266-01 working with AT commands using Altsoft serial.
Works but shuts off after about 8-10 transmits of data to my web provider.
When I reset the power for the ESP8266 it resumes again.

So I was thinking it was getting overloaded somehow someway and I want
to power it down and start it up each time it is ready to send, as a workaround.

So I understand you implemented a deep sleep mode(where is that documented?), with CH_PD pin
connected to a Nano digital port and use a sketch to make it high or low as needed.
I understand the CH_PD needs to be at 3.3 V while the digital port may not provide
that (I think?). Could you elaborate on your solution. Thanks in advance.
