I did some debugging and pinpointed sscanf. It is not reading strings
properly.
Do you have any idea what could be the reason for this?
see attached for an example where the format and the string are from the
code and configuration respectively
TGH I do not understand why it is using %as there, but if %s is used it does
not parse the hex values properly and segfaults when printing the strings.
