Sure, what device are you using? ESP what? 8266? or 32? are you using a nodemcu breakout board? or just the module? I use ESP8266 nodemcu boards and the pins there are GPIO4 (RTS) and GPIO5(CTS) James |

remember that RTS/CTS cross over.. so from the board to the DB plug your using cross CTS/RTS That is literally the board that I made mine out of. James |

In the docs I see mention of RTS/CTS flow control, but I cannot seem to figure out which pins provide these signals from the hardware device. Can anyone shed some light? Thanks.
