CCCD is null in Androidhttps://devzone.nordicsemi.com/f/nordic-q-a/5465/cccd-is-null-in-androidHi everyone, I successfully compiled and loaded the experimental_ble_app_uart onto my pca10028 board. I downloaded and installed the nRF toolbox on my nexus 7 tablet. Connecting and sending uart data from the tablet to the board works fine.

It was a caching problem of Android. It had saved an old setup of services and uuid&#39;s which wasn&#39;t working. After turning bluetooth off and on on the tablet, all is reset and the actual GATT settings are restored.</p> <p>Maybe you could mention in the example description that only sending a certain amount of UART bytes triggers a characteristics notification...(tried for a long time to send only a couple of characters, but nothing happened until I spamed ;) )</p><div style="clear:both;"></div>
