Not able to communicate with esp8266-12F using FTDI usb uart bridge

I designed a PCB based on MPU9250 IMU and ESP8266-12F and FT232RL uart-ttl bridge. You can see schematics for the usb to uart, and esp8266 circuits here. When I researched about the uart part of the circuitry, I see numerous example mentioning FTDI USB modules and esp8266 bare chip programming. Therefore, I build my usb-uart […]
