Hardware Flow Control?
Posted: Sun Dec 18, 2016 11:52 amHi - my first post here, I hope someone can help.
I've bought an ESP-01 module and am using it as a serial to wi-fi bridge for my BBC Microcomputer. It's working well, but at higher baud rates the BBC's serial buffer fills up, and I start losing characters. I'm aware that the ESP8266 can handle RTS/CTS flow control, and using that with the BBC's RS432 should sort out my problems.
I'm looking to buy an ESP8266 module that exposes the RTS and CTS pins. Am I right in thinking I need to find one with GPIO 13 and 15 available?
