ESP8266 Community Forum

- Wed Feb 25, 2015 2:24 pm #10714 Hi, I've written some code to enable remote switching of devices using UDP packets. Now that I have it working I want to relocate the esp8266-01 and no longer require a serial connection.

Is there a setting to disable all the serial output so that if the esp8266 restarts it won't hang due to not having a serial connection?
