    Nothing. It is for people who can’t or don’t want to integrate the module itself into their project. In fact, it does less than the module itself since a select number of pins are broken out.

    Yes, I did it successfully with these modules (RN-42 / RN-41) to sync two pace clocks together over a large range in a master / slave configuration (about 75 meters indoors using the RN-41). They’re still working great!

    The remote module’s address can be set in the configuration mode. If you want persistently paired modules this only needs to be done once and can be done with auto-connect pin settings or in the configuration mode (the latter is easier to understand).

    If you want the host microcontroller to initiate pairing with multiple modules (only one-at-a-time is possible), it either needs to 1) enter the local module’s command mode and choose a different remote address or 2)turn off all other nearby slave modules except the target remote module, and then use the auto-connect mode.

    Depending on the application, one might be better than the other, although in my experience the settings done in the configuration mode are much simpler than the procedures automatically carried out by the module when IO pins are flipped (like auto-connect mode, for example).

    If anyone needs a PCB layout, gerber files, connection help, or design tips for one of these RN-42 / RN-41 modules, check out our project website by googling “ece 4760 time system”. We bought the modules here at Sparkfun and used them to make an Android-controlled programmable pace clock.

    I shouldn’t have wasted a bunch of money buying these. They can be had for $0.35 at other online vendors.

No public wish lists :(
