https://devzone.nordicsemi.com/f/nordic-q-a/10745/read-encrypted-characterisitc-with-peer-manager-failesHi I&#39;ve playing around with the new peer manager a while. I used the example &quot;ble_app_hrs_rscs_relay_pca10028.uvprojx&quot; from the SDK10. After a first fix (see Link ) in the peer manager a bonding can be established successfully.

This worked fine (as expected). Then i pressed &quot;Enable Services&quot;. This failed since i had set up encryption requirement on the CCCD of both characteristics.</p> <p>Then i pressed the &quot;bond&quot; button. The bonding worked, and i was now able to enable services (write to cccd). <img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/6557.Capture.PNG" alt="image description" /></p> <p>I tried with Ligblue for iOS as well. Here i was only able to see the advertisement data. I would not emphasize results with Lightblue all too much. It has varying results from time to time.</p> <p>I guess the weird thing here is that your bonding failed with MCP. How many times did you try with the same result?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/40152?ContentTypeID=1Fri, 11 Dec 2015 08:09:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:25579ec8-5354-4b9d-b09b-23bd0c2c11e8Anders Strand<p>I will try to reproduce it, and get back to you.</p><div style="clear:both;"></div>
