i have bluetooth ble shield v2.1 and arduino mega 2560,
how do i connect these 2 boards correctly?
actually, i connected them and uploaded BLEControllerSketch just like http://redbearlab.com/getting-started-bleshield/
but nothing happened to my android app.
whats the problem should be?
the default jumper setting is correct? any change is needed?
how do i do more trouble shooting?
thanks for any suggestion or more information.
