Has anybody managed to talk to ThingSpeak on an Arduino R 4 (wifi)?

Hi,

I've been trying to use the new Arduino 4 (wifi version) to communicate with ThingSpeak. The r4 has wifi capabilities, how hard can it be? The answer seems to be 'plenty hard' as none of the libraries seem to want to play well.

If anybody has actually managed this, please can you share?

If you want to go without the library, this example shows how to write the HTTP commands somewhat directly without the ThingSpeak communication library. Ill submit an enhnacement request to update the library.

Hi Christopher,

thanks for getting back to me. I'll give it a try but I notice that code needs to include the esp8266.h which I think will cause problems on the Arduino r4. Anyway I'll try it and let you know if it solves the problem,

regards,

Kevin

Kevin,

In this example, they use a library called wifiS3.h. I suspect that will work with the R4 and the commands in the example I sent above.

Please try updating the ThingSpeak library in Arduino IDE to the latest (v2.1.0). It has been tested with the Uno R4 and the Raspberry Pi Pico W (RP2040) boards. Please post on this thread after you've tried it out.
