https://devzone.nordicsemi.com/f/nordic-q-a/39639/quick-question-about-gap-appearance-advertising-dataHi! Just to make sure - if I set advdata.include_appearance = true ; to advdata.include_appearance = false ; inside static void advertising_init (void) I simply shorten my advertising packet by 2 bytes? Thus I get a little bit smaller energyen-USTelligent Community 13Fri, 19 Oct 2018 12:23:32 GMThttps://devzone.nordicsemi.com/thread/153632?ContentTypeID=1Fri, 19 Oct 2018 12:23:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4df55bf1-d250-4c94-80e6-6d5a48a90b1cEinar Thorsrud<p>Hi,</p> <p>You are right, the appearance characteristic is 16 bit so you will save two bytes by not including it. This would make it possible to put other data in the advertising packet, or shorten the packet. As you can see from the&nbsp;Online Power Profiler the gain of reducing the advertising packet by two bytes is negligible, though (difference of about 0.3&nbsp;μC for a typical application).</p><div style="clear:both;"></div>
