Redbear BLE v2 shield + Arduino DUEhttps://devzone.nordicsemi.com/f/nordic-q-a/3376/redbear-ble-v2-shield-arduino-dueI am trying to get the Arduino DUE up and running with the Redbear v2 BLE shield, and SDK 0.9.3. It was a pretty trivial operation with Arduino YUN, but I not so much for DUE. I can get everything to run on YUN, including the basic communication ECHOen-USTelligent Community 13Tue, 05 Aug 2014 20:47:01 GMTRE: Redbear BLE v2 shield + Arduino DUEhttps://devzone.nordicsemi.com/thread/12282?ContentTypeID=1Tue, 05 Aug 2014 20:47:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ae4be5fa-b2fa-4485-af88-7c6b26df37c9bgix<p>The answer to my question can be found in a conversation here:</p> <p><a href="https://redbearlab.zendesk.com/entries/22308466-Arduino-Due-Compatibility">redbearlab.zendesk.com/.../22308466-Arduino-Due-Compatibility</a></p> <p>In short, to use the SPI to correctly communicate to the RedBear Shield on DUE, a different SPI setup is needed, that uses channel &quot;10&quot;, and a divisor of 84 (to cut the SPI clock rate to 1 MHz).</p> <p>This goes for all SPI.xxx() APIs.</p><div style="clear:both;"></div>
