FTPS Transfer Fault Query | Telit Cinterion IoT Developer Community

February 1, 2016 - 10:45pm, 8313 views

Using a EHS6T, using URC's, and calling AT commands within a Java program I have been able to successfully for a FTP transfer. Now I need to transmit to a FTPS Server.

I changed the to ftps://

On issuing the command at^sis0 = 1, I get the URC's:

^SIS:1,0,2100,"FTP open("

^SIS: 1,0,50."Fatal: Service has detected an internal error"

Thus I need to establish what is causing this error - would a SSL error cause this ??.

For a SSL transfer, is there anything else I need to set up - if yes, a link to any information would be appreciated - creation / installation etc.

Would differences in SSL certificates cause this type of error ??

I would appreciate any information on how to trace what is causing this issue.
