https://devzone.nordicsemi.com/f/nordic-q-a/3010/no-longer-able-to-connect-to-redbear-ble-shieldNordic, I am using the BLE Shield v2 and the Arduino Due board to transmit accelerometer/gyro data to an Android tablet app that plots this data. I had this working fine until I attempted to rename the board by calling the function &quot;ble_set_name()en-USTelligent Community 13Sun, 06 Jul 2014 00:40:15 GMThttps://devzone.nordicsemi.com/thread/11358?ContentTypeID=1Sun, 06 Jul 2014 00:40:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5cb459c0-314b-4557-b69d-f10d9f615e6cDevon<p>UPDATE:</p> <p>I reverted back to the old library files (not the newest, most updated library files) and it started working again. Still not completely sure what was wrong or why the newest library files aren&#39;t working for me, or perhaps for the Arduino Due in general, but the old library files do in fact work. Does anyone know what extra functionality the newest library files have that the old ones do not? Here is the link to the old library files in case anyone has had the same problem (<a href="https://github.com/LeadergDotCom/L31_iOS)">github.com/.../L31_iOS)</a>. However, I did add functionality for ble_busy() to ble_shield.cpp and ble_shield.h.</p> <p>Devon</p><div style="clear:both;"></div>
