Hi,
I have successfully ported the Bluetooth low energy API for the Bluetooth low energy shield to the Maple.
The shield that I used is here

The ported source code is available here

The source code has been tested with the nRF UART app on the iOS store and the nRF UART app on Google play.

More details in the Readme in the zip file.
Click upload to Maple and watch the messages from the Bluetooth low energy chip (nRF8001) being printed on the serial monitor (115200 baud).
You can then connect using the nRF UART app and send and recive data.
There is a webinar to get started

Post in the forum if you have any questions.
Thanks
