https://devzone.nordicsemi.com/f/nordic-q-a/3439/effect-of-connection-interval-on-peripheral-power-consumptionI have a custom board using the nRF51822 as a peripheral with the S110 SoftDevice. The centrals are mobile apps, both Android and iOS. The device spends a lot of time in a BLE connection and I&#39;d like to optimise for power consumption.

I&#39;d check to see what peripherals you have enabled vs. table 28 (Section 8.3) of the nRF51822 product specification.</p><div style="clear:both;"></div>
