Hi,
I've just tried to upload the example sketch ReadField with an Arduino R4, updating the library with WifiS3.h rather than Wifi.h. The network connection is OK.
Unfortunately, I get an error code 0 in the Serial Monitor :
"Problem reading channel. HTTP error code 0"
I d'ont konw what is wrong here and how to fix it. I've read it could be result to the update rate, but the delay of the example seemes to be sufficient (15s).

Im sorry, I misread your post, I thought you were writing, not reading. In that case it definitely has nothing to do with the update rate. I would consider trying a different network. Also try using the read command in your browser (also on the api keys tab of your channel;)

The issue lies deep in the implementation of the Arduino R4's WiFiS3 library, which is used to create the client that is passed into the ThingSpeak library. See the issue I have reported to the maintainers of the repo.

Hope they get to that soon. Thanks for digging into the issue @Vinod
