* the memory to be freed once the scan is done
* @attention The values of maximum active scan time and passive scan time per channel are limited to 1500 milliseconds.
* Values above 1500ms may cause station to disconnect from AP and are not recommended.

* @param block if block is true, this API will block the caller until the scan is done, otherwise
