#77224 i am uploading skech given below in my esp-wroom-02...sketch downloaded from github..its giving error like
error compilling for board generic esp8266 module...
Code: Select all//************************************************************
// this is a simple example that uses the easyMesh library
//
// 1. blinks led once for every node on the mesh
// 2. blink cycle repeats every BLINK_PERIOD
// 3. sends a silly message to every node on the mesh at a random time betweew 1 and 5 seconds
// 4. prints anything it recieves to Serial.print
