I have never had any luck getting this module to work, but now I have a project that I would really like to use it in.
Using the slave sketch in the wiki, I can get the module to be apparently discoverable. Both the green and red lights flash.
I have also been able to change the baud rate of the module up and down.
However none of my bluetooth enabled devices can discover the arduino.
So far I have tried:
Galaxy Tab 10.1
Galaxy Nexus phone
Google Nexus 7’ Tablet.
Main PC’s Logitech BT adaptor.
I am at a loss. Anything else I can try?
