I extracted System ID characteristic from the Health Thermometer Service. I modified &quot;service_ht&quot; variable to &quot;service_di&quot; variable and it worked well.

Testing with the hts example here , I can see the System ID characteristic. I would suggest to test with fresh copy of the example/SDK.</p><div style="clear:both;"></div>
