I&#39;ve added the dfu service to my existing NUS/UART service. In the nRF connect app I can see both services and I can send test data to the nRF52832. But, my ios app doesn&#39;t work anymore.en-USTelligent Community 13Wed, 03 Oct 2018 14:25:26 GMThttps://devzone.nordicsemi.com/thread/151506?ContentTypeID=1Wed, 03 Oct 2018 14:25:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29b773d5-69db-4b08-a39d-e5a2cc215ae7buoy112<p>well, I&#39;m shocked but simply turning bluetooth on/off on my ipad did the trick. Is there a way to &quot;automate&quot; this process so when I issue updates to the app/firmware the cache gets cleared?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/151416?ContentTypeID=1Wed, 03 Oct 2018 11:57:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b41932e5-5346-4975-8154-d45dcbd17d76Hung Bui<p>Hi Buoy,&nbsp;</p> <p></p> <p>Please make sure you have &quot;service changed&quot; characteristic enabled in both your application and in the bootloader.&nbsp;</p> <p>When testing, please try to delete bond information and turn off and on Bluetooth. We just want to make sure there is no attribute table cache on the iOS device.&nbsp;</p> <p>You may want to use the nRFConnect to check if you still can see the NUS service and characteristic when connect to the device.</p><div style="clear:both;"></div>
