I bought this optical fingerprint scanner from amazon.
I looked on you tube and googled how to use it but I keep getting this error message when I use it with the SDK that's made for it.
I m using logic level converter and aurduino passthrough to communicate with it.
the error code says " the module no support auto-set functuin".
I don't know what that means!!
Is this issue anything like this one?
that's my previous post
the mod commented that I didn't posted correctly so I reposted it as properly as I can.
You could have taken the mod's advice, tidied up that post using the "quick edit" or "modify" controls, and we wouldn't be here, asking for a mod to lock or delete your other post (hint).

dude please help me I m stuck with that error..
I am serious.
I m not familiar with these strict rules.
I will learn them as I use this forum.
The rules are simple, not strict:
You post as much detail as possible,
you post code (not pictures of code),
you post error message (all of them, not pictures of error messages) and
you post a schematic (not Fritzing)
that was not a moderator, that was me, and that thread is not locked

You know, you could have known how to properly post a question before even posting here, just by reading the "How to use this forum" sticky that's on top of every page.
One of the most important rules is actually not explicitly mentioned there, but is actually the key to the whole thing: do your own homework!
You should understand that we are not trying to be mean or to put you off of the forum, however the forum gets thousands of similar posts. We've seen posts like "...my led doesn't light, whats wrong..."
What we expect of you before you post your question:
You use the obvious internet resources to diagnose your problem as best you can before your post. In this case the Sparkfun instructions. Did you google and find these? Did you read them thoroughly and follow what they suggested?
You triple check your connections.
You provide us with a clear and complete description of your hardware and software, with Links where appropriate.

I did a Google search on the following error and this post was the only hit:
"the module no support auto-set functuin"
I was stumped until I realized I had an older fingerprint scanner (GT-511C3) but was trying to use a new version of the DEMO software.
I downloaded an old version of the DEMO software here and now it works fine!
Hope this finally solves your issue.
