Pretty much what I have done with these are posted above. The above example is a data logger for a GPS. The link to the post from Brian T has the writing example. You can see on the GPS example how to collect data and save it to the module.

To be honest, the VDIP thing works well but is a pain in the _ _ _ .
I purchased two and ended up with one in the logger and the other is collecting dust. The data sheet is hard to follow and if it was not for Brian's post I do not think I could have made it work or would have given up.


If you are having a specific problem I am sure we can work though it.
Let us know.
