  • Learning more as I go here:) The commands sheet ( http://www.sparkfun.com/datasheets/Wireless/Bluetooth/rn-bluetooth-um.pdf ) says this:

    Page 23: Discovery and Connection Example of a Master Discovery/Connection Sequence From power up and no connection: 1) Perform an Inquiry to obtain BT_Address (unless it is already known).

  • Reading the data sheet, I see that:

    Pin#19: HIGH when connected, LOW otherwise

    Assuming the word "connected" = module paired withed secondary bluetooth device, you could poll this pin and when it's high, assume your secondary device (e.g., Cell Phone) is within range.

    Any thoughts/comments on this interpretation of the data sheet?

  • I'm also interested in the answer to this question -- I would like to know how to tell when the module "senses" (or reads) an in-range secondary bluetooth device's MAC address. Any suggestions/solutions?

  • Did you ever get this working? I'm looking to do the same.

No public wish lists :(
