Hi Vandita,
You can use the ?byte? data type to transfer a file.
Let me share you the example representation so that you could get a tip for
your need.
/file/transfer
{
rt : [?x.com <http://x.com/>.mycompany.file.transfer?],
if : [?oic.if.s?],
blob : ?alsutomqcijrt;oqmjrogkjmdiou209?..(byte string value)
?, <? BYTE data type
size : 1000
<? int64_t data type.
}
I have tested with 50MB file and it worked fine.
However, you will need to check and find the proper file size which meets your
goal
?cause the speed performance varies based on the file size.
I hope this would help you.
Thank you.
Jay.
