Dear All,
I am trying to connect an ESP32 board to Cayene throuhy CAYENNE_OUT function using wifi as the connection below (code below).
I constant get the “‘Cayenne’ was not declared in this scope” message and I am using a TTGO LoRa ESP32 board set as ESP32 dev board in the boards manager.
I have noticed that by trying different board types as well as Cayene MQTT libraries, I get different error messages that mainly point to WiFi library problems.
Has anyone come across the same issues?
Thank you
