Okay, that's good (though unfortunate) to know. My only question is, why do (multiple) diagrams for the ESP8266-12E Dev Module show 'RX02' if it doesn't exist (can't be used)? I have at least 3 different diagrams that show RX02 being available on D7/GPIO13/Pin-21 of the Dev Board (as TX02 is shown as D8/GPIO15/Pin-20). If it doesn't exist/can't use it, then the diagrams shouldn't show it.
Again, thank you for the info. Very good to know.

Unfortunately, UART1 has only TX, this missing RX on UART1 is by hardware design.
You will never see it, except if Espressif provide new chip revision after redesign.
