Guys,

I have the following Hex string

aa557fc001824d3038303843475735303030532d4250ffffffffffffffffffffffffffffffff39353030304250533230425730303232333630303431302d30343030312d3038473431302d30

Parts of this decode as ASCII text e.g. 4757 = GW - as can be seen in the screenshot below

Further along is a serial number

I am trying to feed this to Steves Buffer Parser node - but can not hit on the right combination to get anything out

If i set it to treat it as Hex i get

So i believe i have the offsets and length right

But i can not get it to output the ASCII representation of the Hex characters

I have tried Hex, ASCII, String and am not getting the output - only hex gives me something but it is just the hex characters.

Any pointers ?

Craig

There was a bug in my parsing that was fixed about a week or 2 ago. Make sure you have the latest version installed Craig.

If you can't update, use `binary` type instead.
