Using Arduino UNO and WIZ550io - crashes when using ethernet.begin(macData).
Using ethernetreadwritestring example.
Can not ping WIZ550io. Connected to switch along with PC and connected to cable modem.
Trying to send data to exosite site.
If I comment this out, the serial monitor will display:
Connecting to Exosite...Connected
Error: HTTP Response Timeout
Error Communicating with Exosite

Post the code or a link to that example code.

Jabraham, that example is for the Ethernet shield. Is that module interchangeable with an Ethernet shield?

This is the example: arduino_exosite_library/examples/EthernetReadWriteString at master · exosite-garage/arduino_exosite_library · GitHub

Had wire for MOSI and MISO crossed.

In the program revised:
Ethernet.begin();

Works ok now...
