Hi!
My question is for the purpose of power calculations for both the nRF52832 and nRF52840 for BLE use only.
I haven't been able to find a reference for this.
I see that the current requirement for the CPU is ~7mA and the BLE TX is at 8.7mA (from memory).
Do these devices TX or RX while the CPU is running, so that the peak current is around ~15mA?
We want to see what to expect when a CR2032 reaches low voltage and the internal resistance gets high. We are concerned about the brown-out-detector getting triggered at these levels and need to know the lowest possible voltage that we can run with on the battery!
Are these two events serialized by the hardware (is the CPU halted when TX or RX) ?
Thanks.
