nrf52832 BLE consumption

[Robert]

I am working on nrf52832. For my task, I need to knoow how nordic find out the Total average current on Online Power Profiler for BLE(https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble).

I also need to estimate the current consumption while nrf52832 is sending a full data packet on BLE.

Best regards.

Why do you need to know that?

That is what the power profiler tells you!

Thanks for answering. In fact, i want to calculate the power consumed by nrf52832 for one single data packet transfer to estimate the maximum number of tranfer before my capacitor discharges.

So should I multiply the "Total average current"  by the transfer duration? or I add  Pre-processing power with Crystal ramp-up power with Standby power with Start radio power with Radio TX power with Radio switch power Radio RX power  with Post-processing power.

Reference : Online Power Profiler for BLE (https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble)

I'm asking that because the result is different for each of those two methods.

A capacitor (like a battery) stores charge - so it's really the charge you need to know - not power or current.

Again, this is shown by the power profiler:

Thanks, I appreciate it.

One more questiion, can you share with me the main difference between "Adverdising(Connectable)" and "Connection(Central)"  on the "Online Power Profiler for BLE"?

They are what they say - one is while the unit is doing connectable advertising; the other is for a Central while connected.
