I have developing product using ESP8266-01 and interface with other host MCU, Host MCU to ESP communicate using UART with AT command. our product is on Battery source for low power consumption i have control WiFi_CH_PD pin with host GPIO MCU if i want wifi connection with host MCU that time i high GPIO pin and send AT command to ESP via UART.
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 for your reply i read this document for low power consumption but as of now i have ESP8266-01 module so in that not connection for deep sleep mode. 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....
