+/* Update a parameter
+ *
+ * This will just update the value of a parameter with esp rainmaker core, without actually reporting
+ * it. This can be used when multiple parameters need to be reported together.
+ * Eg. If x parameters are to be reported, this API can be used for the first x -1 parameters
+ * and the last one can be updated using esp_rmaker_param_update_and_report().
+ * This will report all parameters which were updated prior to this call.
+ *
+ * Sample:
+ *
+ * esp_rmaker_param_update(param1, esp_rmaker_float(10.2));
+ * esp_rmaker_param_update(param2, esp_rmaker_int(55));
+ * esp_rmaker_param_update(param3, esp_rmaker_int(95));
+ * esp_rmaker_param_update_and_report(param1, esp_rmaker_bool(true));
+ *
+ * @param[in] param Parameter handle.
+ * @param[in] val New value of the parameter.
+ *
+ * @return ESP_OK if the parameter was updated successfully.
+ * @return error in case of failure.
