Quick question about GAP appearance advertising data

[Pawel Niedbala]

Hi!

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 energy consumption and a little more space for my manufacturer data?

Thanks

Hi,

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 Online Power Profiler the gain of reducing the advertising packet by two bytes is negligible, though (difference of about 0.3 μC for a typical application).
