I was playing around with your code:
https://codebender.cc/sketch:91073#TinyShield_NRF8001_BLE_Example.ino

for a project Im working on for fun. curious if anyone has the xml for the GATT for nRFgo.  I want to make some changes but don't want to have to redo the whole thing. it wasn't included in codebender. It would be great if i could import it into the tool and work from there.

The XML is available from Nordic's github: https://github.com/NordicSemiconductor/ble-sdk-arduino/tree/master/libraries/BLE/examples/ble_uart_project_template

Definitely much better to start there if you want to change a parameter or two.
