Hi guys, I am trying how figure out the the devzone.nordicsemi.com/.../ works or ecuations to estimate the battery life using a central module.
My central device is battery powered and it goes from deep sleep to active each 10mins transmitting a Write to a peripher 20bytes and an indicate to the central 12bytes size. The connection time is about 50ms and the peripheral advertising interval is 20ms.
I am trying to calculate it in the following way:
RF transmitting = 8.1mA RF listening = 6mA
A average RF transmitting/reciving is 7mA per sec using DCDC enabled Sleep mode is 4uA per sec
estimate RF activity = ( 7mA x 0.05s)
Estimate Sleep mode consuption = 4uA x 3600s x 10s)
Estimate consumption = Estimate RF activity + Estimage Sleep mode consumption
Estimate Battery life = battert capacity / estimate cosumption
Is iit a correct way to estimate the battery life?
Thanks.
