Battery Lifetime in BlueNRG current consumption estimation tool

[AF_it]

Which is the state between two advertising events for the calculation of the battery lifetime?

Shutdown or Deepstop?

Is the current profile shown in the plot obtained when exiting shutdown or deepstop state?

Thanks

Hello,

Between two advertising event, BlueNRG will be in sleep with timer.

If considering BlueNRG-2 (please refer datasheet table 212), you'll have 0.9uA typ if using 32kHz xtal or 2.1ua typ if using internal RO (no 32KhZ XTAL).

If considering BlueNRG-LP (please refer datasheet table 11) , you'll be in deepstop with timer so 1.06uA typ if using LSE (with 32kHz xtal) or 1.24uA typ if using LSI (no 32kHz xtal)

The profile shown on this tool is just the active phase (whatever advertising or connected).

Then it adds the sleep mode with timer value to display the estimated average value and battery lifetime.

Regards

Laurent
