Dear readers,
I use Cayenne for some projects involving a Raspberry Pi. Last week I got a Seeed Wio Terminal and I would like to use it with Cayenne too. Sadly I don’t get it working because I have almost no knowledge with the Arduino IDE (and I have to use the Arduino IDE for WiFi functions). I checked for libraries which support Cayenne and the Wio Terminal or at least the SAMD51 microcontroller, but didn’t find anything. If I use the Cayenne examples I get always errors like:
fatal error: WiFi101.h: No such file or directory
and:
Error compiling for board Seeeduino Wio Terminal.
So I tried replacing the code snippet which includes the WiFi101.h to rpcWiFi.h (which works for the Wio Terminal), but then I end up with this error:
WiFi101Shield:38:23: error: expected constructor, destructor, or type conversion before ‘;’ token

Does anybody have an idea how to make this example work for the Wio Terminal or how to connect the Wio Terminal to Cayenne? I used the WiFi101shield example for this one, but the other connection examples give the same kind of errors.
