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,

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
