It is generic since the two devices can be from different vendor. For BLE, if we run nRF UART application on one device, the otheren-USTelligent Community 13Wed, 31 Aug 2016 04:37:52 GMThttps://devzone.nordicsemi.com/thread/61346?ContentTypeID=1Wed, 31 Aug 2016 04:37:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2b911253-fe1d-4e07-9ebd-c1a09a3e854fdjqtsg<p>Thx, got it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61345?ContentTypeID=1Wed, 31 Aug 2016 04:10:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a33a6951-8e2d-4fec-934a-85f89e62f2d5RK<p>No there isn&#39;t a generic UART service defined in BLE because the Bluetooth SIG hasn&#39;t defined one.
