https://devzone.nordicsemi.com/f/nordic-q-a/44726/esb-and-ble-which-mode-saves-more-energyHi all, I make a key using nrf52832. It tranfer data to other device. I have 2 option for this. Using beacon (BLE) or Enhanced ShockBurst (ESB) . I want to optimize energy. So which mode saves more energy ? Pls, answer my question !!

Less processing involved. This requires the the central to be scanning all the time to receive the packets.</p> <p>When you say beacon, do you mean advertising mode? Are you just sending a few bytes in an advertising packet or do you need to connect to the central to send more data?</p><div style="clear:both;"></div>
