About power consumption in GAP and GATT mode

Hi Devzone,

I know that more specific information is needed (time interval, Tx power, data length, ....) to make a comparison between GAP and GATT. But in general, which one consumes more power?

For instance that I need to send some data to central, should I use advertisement packet or gatt services for better energy?

I already know Online Power Profiler, but still need more advice.

Thanks in advance.
