Have you figured this out? I am having the same problem. I successfully connected the RN-42 modules to my iPhone, but cannot get them to connect to each other.

up up!

Reviving this topic because I have some doubts about connecting to RN42 modules.

And my first question is:

Using the authentication system for pairing, the first time the master module tries to pair with the slave module they should exchange pin codes. Where are these pin codes saved or do I have to program the slave module to send the pin code at some point?
