Can I direct use Blynk library ( https://github.com/blynkkk/blynk-library ) to connect to Cayenne and send data?
While you may be able to get this to work by modifying the Blynk library, I would suggest to avoid this as Cayenne uses a modified version of Blynk already to drive our Arduino connectivity, and this could cause incompatibilities and issues.
Is there some feature that library offers that you’re not finding an equivalent for in the Cayenne library?
We also have a MQTT library for Arduino if you are wanting to try that out.
See this post for more information on adding your ESP32 to Cayenne, we have lots of users connecting ESP microcontrollers for their projects already and should have native support in the Cayenne UI within the next month.
If you have any trouble with those options, make a thread and we’d be happy to help you out.
