How do I Set the Device Name to Read Only?https://devzone.nordicsemi.com/f/nordic-q-a/16931/how-do-i-set-the-device-name-to-read-onlyHow do I change the properties of the Generic Access service&#39;s &quot;Device Name&quot; characteristic to be Read Only, not Read and Write? I see this BLE_GAP_CONN_SEC_MODE_SET_OPEN(&amp;sec_mode); but this only offers security modes related to bonding and MITMen-USTelligent Community 13Mon, 10 Oct 2016 17:02:54 GMTRE: How do I Set the Device Name to Read Only?https://devzone.nordicsemi.com/thread/64903?ContentTypeID=1Mon, 10 Oct 2016 17:02:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ce97b094-619a-4ae8-9f6a-ec6b11c4ff6fAndrew<p>That worked well. I had to make sure that I updated the nRF Connect app (deleting the bond, and re-bonding) so that it would re-scan the characteristics to reflect these changes as well.

Therefore, to make it read only, the sec_mode parameter should be set to &quot;no access&quot;:</p> <pre><code>BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&amp;sec_mode); </code></pre><div style="clear:both;"></div>
