I'm running the Uno board and want to connect the BLE Bluetooth shield (http://redbearlab.com/bleshield/) to control the Braccio Arm I have.
When I sit the Braccio Arm Shield on the Uno everything works - I can control the Arm.
When I sit the Bluetooth Shield on the Uno, everything works I can find the device and connect to it using the IOS App.
When I sit all 3 together, I can still control the arm but can no longer find the Bluetooth device.
Any ideas as to why this is?
