https://devzone.nordicsemi.com/f/nordic-q-a/82868/device-name-has-only-4-lettersHello everyone, my application is build based on the mulitrole example. The device name is somehow limited to 4 letters. I checked: init.advdata.name_type = BLE_ADVDATA_FULL_NAME #define BLE_GAP_DEVNAME_MAX_LEN 248 Do you have any ideas whaten-USTelligent Community 13Sat, 18 Dec 2021 12:46:46 GMThttps://devzone.nordicsemi.com/thread/344221?ContentTypeID=1Sat, 18 Dec 2021 12:46:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:172b3eb1-1c34-4a7b-96b2-d267a7a43513Hani_Montana<p>Yes I followed and it worked, but the problem with the 4 letters is still there. Where can I check my advertising data?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/344145?ContentTypeID=1Fri, 17 Dec 2021 12:48:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3e6e830e-6982-474e-8622-2012f2d52d86Hung Bui<p>Hi Hany,&nbsp;</p> <p>I found that it&#39;s a duplicated case from<a href="https://devzone.nordicsemi.com/support-private/support/281349"> this case.&nbsp;</a>&nbsp;Have you followed the suggestion from Sam &amp; Rob ?&nbsp;<br /><br />Note that the maximum advertising packet size is 31 bytes this is including the flags and overhead. So if you have other data in the advertising packet, you may not have many left for the device name.&nbsp;</p><div style="clear:both;"></div>
