Not able to communicate with esp8266-12F using FTDI usb uart bridge
So problem is pin11 GPIO2 of the ESP12F. It must pulled up to 3.3V for each operation mode of the esp. However, datasheet of the ESP12F states that GPIO2 is also I2C_SDA pin. Does it makes sense for pin that needs to pulled up during operation to be SDA in the same time?

Here is a state configurations for normal operation mode and flashing mode
