I control this module using host MCU via AT command. Now for low power consumption i control ch_pd pin ON/OFF. Can you tell me is it right to direct connect this pin to host MCU GPIO with 10K, Because if i connect this to direct MCU my host MCU is resetting at the time of credentials configuration. Is it any way to do for controlling wifi ch_pd pin using transistor, MOSFET or other as well. If yes please suggest me which on and how to do connection.

Looking forward to your rely....

Thanks,
Vishal

But problem is when i send wifi credentials to ESP for configuration at that time i also high WiFi ch_pd pin then send "AT+CWJAP_DEF="SSID_Name","PASS"\r\n". But at that same time my Esp and host mcu reset and ESP is continue with old wifi credentials not configure as per new SSID name and password.
If i connect ch_pd pin with direct vcc itis working fine but my battery power consumption is very high continuously.
I have connect WiFi ch_pd pine to host GPIO with 10k resistor.
Please help me what should i do ??
Thanks,
Vishal
