If the calibration date can’t be updated in base station calibration, the following two
solutions can be adopted:
Make sure that ftp (Serve-U) is working properly: for example,
the user name and password for calibration are correctly matched; the folder of calibration
file is correct or not, etc.
Make sure that the FTP IP information is correctly set in
performance logs.
