Hello,
I purchased the Olimex ESP32=POE-EA Development Board and I am having trouble getting started using Arduino IDE. My application requires TCP/IP serial communication between the Arduino Serial Monitor Window and a TCP/IP serial test window on the same Ethernet Network.
I have the "Olimex ESP32-PoE" board selected and I am trying the "ETH_LAN8720.iso" example. No errors, the Ethernet LED's are solid GREEN, and Blinking Yellow..
Within the Arduino serial monitor, I receive no messages at all..
Question to Olimex Moderator:
Where can I find "working", basic, starter Arduino code for a TCP/IP serial connection?
HELP ?!?!?!?
The board is supported in the official Arduino package for ESP32. So, if you haven't already first install the official package, follow the advice here:
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html
Then go to Tools -> Board -> Olimex ESP32-POE and select it then also select the COM port of the device.
Then load the default example for Ethernet, from File -> Examples -> Ethernet -> ETH_LAN8720. Compile and upload. Check the serial monitor.
Make sure to explore the rest of the examples and if you need more advanced examples check our GitHub repo here:
