Hi Luiz,

Thanks for the response.  I guess if the Pair() fails with Authentication
failure, that implies the device does not support it?  I was playing with
this TI sensortag and wanted to double check how it was connecting.

So does the authentication get setup by the agent?  And the Pair() to the
agent determines if the link will be encrypted?

Cheers,
Don
