ESP8266 to act as a gateway between two PCs to transfer the data



  • I am new to arduino and to ESP module, my task is to make ESP8266 to act as Gateway for the communication between two devices. so when I transfer a data, it need to be transferred through the gateway to the other PC. I installed arduino and installed Mysensors library in it.I am using esp8266 gateway example, while compiling it is showing the error
