https://devzone.nordicsemi.com/f/nordic-q-a/31234/location-and-navigation-service-experimentalHello Everybody, I am trying to implement the LNS Experimental Service from SDK 14.1. I am asking myself why they split the flags in two seperate packets, because that is not what the BLE Spec is suggesting. I thought the 16 bit at start are the flagsen-USTelligent Community 13Fri, 09 Mar 2018 15:07:55 GMThttps://devzone.nordicsemi.com/thread/123730?ContentTypeID=1Fri, 09 Mar 2018 15:07:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3ca1ce44-1378-4763-a930-2cf63b9ae98cMartinBL<p>Hi,</p> <p>I&#39;m a little puzzled about this myself, but unfortunately the guy who wrote the code doesn&#39;t work at Nordic anymore so I can&#39;t ask him about his reasoning.&nbsp;</p> <p>The example is starting to get old and hasn&#39;t changed much since SDK 11. At that time our Softdevices didn&#39;t support MTUs longer than 23 bytes, and I wonder if the point of splitting the packets was to make sure that the payload&nbsp;didn&#39;t exceed this limit. Note the warning in your link: &quot;...<em>it is possible for this characteristic to exceed the default LE MTU size</em>&quot; (default was, and still is, 23). However, if this is the reasoning, the method seems a bit flawed since you might end up sending two packets while all the data could have fitted into one.&nbsp;</p> <p>Nowadays you can increase the MTU size, and I don&#39;t see why you can&#39;t modify the example and fit all the data into one packet.</p> <p><em>Also is there a good method to distinguish the 2 packets in Android?<br /></em>Maybe you can use the flags?&nbsp;</p><div style="clear:both;"></div>
