EC25-E and EG25-G FTPS Explicit server Login

Hallo, i use multiple EC25-E and EG25-G in our embedded devices. Until now we use FTP to down and upload our data.
Now we are forced from our IT department to use FTPS. Both (EC25-E and EG25-G) devices offer selection of Explicit FTPS connection in - EC2x&EG2x&EG9x&EM05_Series_FTP(S)_Application_Note.pdf:

AT+QFTPCFG=“ssltype”,0" 0 FTP client
AT+QFTPCFG=“ssltype”,1" 1 FTPS implicit encryption
AT+QFTPCFG=“ssltype”,2" 2 FTPS explicit encryption

setting ssltype = 2 does not

There is only a implicit FTPS example provided.

  1. Does the EC25-E and EG25-G support explicit FTPS?
  2. Following the example, with setting ssltype = 2, NO explicit FTPS connection can be established,
  3. How to change the implicit FTPS example to make it work for explicit FTPS?
  4. Is there a explicit FTPS example available?
  5. How does the Certificate Exchange work with explicit FTPS

informations about this topic would be highly appreciated.
regards,
feuerwolf
