ESP8266 Community Forum

Hi Team,

Can we use ESP8266EX without External flash to make it work as WiFi to connect to My network by configuring through UART of ESP8266EX.

Can I have schematic like with external MCU with only UART (Tx,Rx), CH_EN, RST pins are used.

Please provide a solution for above query.

Thank you,

No, the ESP is an MCU only; it needs software (and thus memory storage) to do something.
