FTPS sara U270 problem with data transfer

0 votes

Dear Ublox forum users,

 

I have a problem with the FTPS connection of the SARA U270 to the remote server. My AT script is as follows:

 

AT+UFTP=1,"xxxx"

AT+UFTP=2,"xxxx"

AT+UFTP=3,"xxxx"

AT+UFTP=8,1

 

AT+UFTPC=1

returns 1,1 (connected OK)

 

I can move in the directory tree with no problem but I am not able to create any file or download or list files. Like the control commands working OK but other data transfers not. When I  tried to connect with explicit active FTPS mode from filezilla or total comander to our server there were no problems.

Just for info classic FTP (not FTPS) on the very same server working just fine.

Many thanks for any help, 

Best regards,

Jan
