Serial on ESP8266

[dtex]

Trying to use serial on the ESP8266. Using WiFi should leave pins 1 and 3 of Serial0 available for use correct?

Serial can currently be used to print debug messages when using WiFi, however some changes are required to use Serial for other purposes when WiFi is the primary transport.

First I would make sure Serial write for debug is working on the ESP8266. Wire up pin 1 and uncomment SERIAL_DEBUG here.

If that works, then try need changing this line to #elif defined(ESP8266_WIFI) (also be sure to comment out SERIAL_DEBUG). You may also need to define pin 3 as ignore on the following line, but try first with just 1.
