Goal : send data from Arduino Ethernet to ESP8266 wirelessly
Proposed solution : send data from Ethernet to MQTT server then reading data from MQTT server using ESP8266
1- Which libraries should I include in each part of code (Ethernet/ESP8266) ?
2- Is there any better method to send data from ethernet arduino to ESP8266 without MQTT ?
3- I need some examples to better understand how can I do it
