I&#39;m using a RedBear BLE Nano v2 to act as an intermediate between an Arduino Uno and an Android App. I&#39;m using the nRF5_SDK v15 librariesen-USTelligent Community 13Tue, 24 Apr 2018 13:50:23 GMThttps://devzone.nordicsemi.com/thread/129594?ContentTypeID=1Tue, 24 Apr 2018 13:50:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b85851dc-c427-4333-be93-b1d773fcea6eHung Bui<p>You mentioned you are using SDK v15. I assume you are not using libraries from Redbearlab and can run our example directly.&nbsp;</p> <p>&nbsp;</p> <p>If it&#39;s the case, you can simply use our UART library to communicate with your Arduino.
