I checked it
but this server is not accessible “http://www.quectel.com:8111/DFOTA/A2B.pack”.
and after a moment, the module returns +CME ERROR: 6503.

You can refer to the local upload file upgrade method at the end of the document:DFOTA over Local File System

please send me local delta firmware package
