When is the function below called in Telink mesh sdk? I don't understand from the description in the sdk document.
"int rf_link_response_callback (u8 *p, u8 *p_cmd_rx)"

Please explain with an example.

In general, for example, in the case of a light switch, it was analyzed that the function below is called to turn on/off the light.
"void rf_link_data_callback (u8 *p)"
