Re: ASN1 - syncInfoValue
I figured out my problem from yesterday... It seems the decoding
specification I was using did not set the certain boolean elements to
optional so they were expected and the decoding did not work properly.
I have another issue. I am essentially just wondering essentially how
are the syncUUIDs encoded? When I try to print out the decoded OCTET
STRINGS they are not standard ascii or utf-8 characters. Here is a dump
of an intermediate response message. (seems the same as the last one I
posted)
30 81 92 02 01 02 79 81 8C 8A 18 31 2E 33 2E 36 0.....y....1.3.6

I'm not sure how to translate elements of the set of syncUUIDS into
something I can use. Are they base64 encoded or what??
Thanks for all your help.
