We are developing a new product that requires extremely low power consumption with a target to run advertising intervals of between 2 to 10 seconds.
We are using the nRF52805 with S112 softdevice
The power-profiler states estimate consumption of < 10uA at 2 second interval - we are using the nRF52810 as a proxy for the 805 estimates.
Our testing:
1. All external circuitry connected, no BLE, all peripheries disabled (except necessary GPIO), RAM on and waiting for GPIO interrupt approx = 10 uA
2. App_timer initialized without BLE = 250uA
3. App_timer + BLE = 400uA
Questions:
1. Does the power-profiler estimate take into account the timer needed to time the advertising interval?
- Is this additional or included in the power profiler estimate?
2. Do we need to use the app_timer for timing advertising?
3. How do we achieve the estimated power consumption?
