ESP8266 Community Forum

I also wrote a receiver-only software serial library for a project I was working on before checking properly if someone else had already written one oh well! https://github.com/scottwday/EspSoftSerial if anyone's interested.

Does anyone know if UART1 can be remapped off GPIO2? I use UART0 to communicate with a Teensy3.1 (not AT commands, basically a inter-processor communications channel), so I generally use GPIO2 to debug. Unfortunately, if you add a SPI device (such as a SPI OLED), using GPIO2 as a debug is a very bad idea as it causes the 8266 to hang and the watchdog timer reboots the chip.

There is an API called system_set_os_print() which disables debugging ... might this be what you are looking for?

hmmm, isn't it be "off" by default to not interfere with the "standard" use of gpio's?
