So I created my own timer for update, but the same error message kept showing: "E (6309) esp_rmaker_param: Current time not yet available. Cannot report time series data."
The board I am using is ESP32-C3 and here is the code. I have done several debugging and found out that the program cannot execute this statement: if (interruptCounter > 0 && wifi_connected) {}. Can anyone help me to see what is the problem? So many thanks
