Callback issue in the FTP get function of 9160

Question

How to determine if the download is complete when downloading files from the FTP server using the ftp_get function? 
 Although Ctrl_cb will return code, in my actual testing, when downloading a large file, the download was not completed yet, and Ctrl_cb already returned 226 code indicating that the transfer was completed. However, there was no callback message when the download was actually completed. 
 I haven't tested the ftp put function yet, may there be similar issues as well?

Hi dejans 
 I tested CONFIG_FTP_CLIENT_KEEPALIVE_TIME, but it didn't work. Instead, I modified FTP_DATA_TIMEOUT_SEC in ftp_client. c to solve this problem. It may not be the best solution, but currently it's not a big problem. Simply put, the time for ftp_get cannot exceed FTP_DATA_TIMEOUT_SEC , otherwise it will return -116, with a default of 60 seconds. Therefore, I will change this value to a few minutes. Perhaps you can improve this place a bit? But for me, this problem has been solved. 
 Anyway, thank you for your help.
