QuestionsCategory: General QuestionESP8266 Software serial TX, UART RX
John asked 3 months ago

I have a project that talks serial to another device. I do not have control over the message format.
Having read all I can find about alternative UARTs, serial swap etc., I have concluded that my best bet is to use Software serial for transmit(I am thinking that I can use a pullup to avoid a bunch of NULLs at boot-up), and use the normal RX0 pin for receive, as I believe it will be more robust than Software Serial receive.
Does this sound sensible and feasible? Baud rate is a pedestrian 9,600.
