SMTP -Java version of HyperTerminal version giving ERROR | Thales IoT Developer Community

I am able to send an SMTP with attached fileusing HyperTerminal, however when trying to do the same using Java, I get an error. I am having problems detecting where my error(s) is. The HyperTerminal version works fine and I receive a SMTP with attached file, but my JAVA version just generates ERROR – with no other information, although verbose error messages enabled.

Any help would be appreciated to help to identify where the issue is.

 

At+cscs=?

Gives ^cscs: GSM ucs2
