Just a lack of competenze on esp32

[Gcaravell0]

I'm using a board with an ESP32-WROOM-32U, 16MB module.
I have replaced my ITC-5 with an Arduino DUE and the library of Timo ( thank you so much). Now I want to implement a WiFi bridge with the esp32 board and I want to use the example of the library.
The code run successfully on the board but I have some configuration doubt.
In the repository is specified that the pins used are GPIO 16 and GPIO4 but I didn't understand if I have to connect them to the serial port of the DUE board and read the Actisense data or I have to connect them to, for example, CANRX CANTX of the mcp2562.
Sorry for the stupid question and thank to whom will help me in advance.

You connect them to tranceiver e.g., MCP2562. Please read documnt https://github.com/ttlappalainen/NMEA2000/blob/master/Documents/Connecting_hardware_to_NMEA2000.pdf . On doc Teensy has been used as schematics example, but it does not make difference on connecting tranceiver.
