Issues connecting to Nordic BLE UART service peripheralhttps://devzone.nordicsemi.com/f/nordic-q-a/11562/issues-connecting-to-nordic-ble-uart-service-peripheralHi All, I&#39;m facing unstability in connecting my Central BLE device based on bluez to connect to Nordic Uart service based device. For every 10th or 11th connection , it gives Connection Refused or Characteristics Read failed or Characteristics Writeen-USTelligent Community 13Fri, 29 Jan 2016 14:39:43 GMTRE: Issues connecting to Nordic BLE UART service peripheralhttps://devzone.nordicsemi.com/thread/43688?ContentTypeID=1Fri, 29 Jan 2016 14:39:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fb6b69d6-da68-4dff-98dd-d946dc1136a5Stefan Birnir Sverrisson<p>Hi Brajesh.</p> <p>First look, use the app_uart library instead of simple UART. The app_uart library is use e.g. in the simple_adc example in nRF51 SDK 10.0.0. The simple UART is known to cause problems, so remove that is what I would first suggest.</p> <p>If using app_uart does not solve the issue, can you inform me what hardware/kit you are using, what softdevice and what version and what SDK version. If possible, a complete project would be better so I could reproduce the issue on my side.</p><div style="clear:both;"></div>
