So I ask to you if is there an app for android phone to implement this application and if Nordic has developed a ble_cts service (client) to put it in SDK (ble_services folder). Now I developed a cts service but I can not make it work. Thank, Paolo</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16543?ContentTypeID=1Mon, 12 Jan 2015 17:52:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b64bc45d-4623-427e-afd9-6d82c58fc582Stian R&#248;ed Hafskjold<p>So, if I understand you correctly, you want to connect your nRF51822 to an iOS device, and read out the current time information from the iOS device. The iOS device acts as a server, and the nRF51 as a client.</p> <p>Can you please provide me details on how the iOS server is configured? I was able to compile and run your code, and discover the services on the nRF51822 from MCP. But I need to know how the iOS server is set up in order for the nRF51822 to discover the services.</p> <p>Did you try to read characteristic by UUID? <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/7.1.0/s110/html/a00875.html">developer.nordicsemi.com/.../a00875.html</a></p><div style="clear:both;"></div>
