Thus, you won&#39;t be able to qualify as a BLE Mesh device.</p> <p>Other than that I can&#39;t say which issues you might run into, as we haven&#39;t tested this (cause it breaks spec.). <br />But on top of my head I can&#39;t see that it should be any specific issues with implementing this yourself.</p> <p>Br, <br />Joakim</p><div style="clear:both;"></div>
