Online Power Profiler for BLE: questions and a bug

[9il]

Hello,

Please help me to figure out how to use https://devzone.nordicsemi.com/power/w/opp/2/online-power-profiler-for-bluetooth-le for time interval estimation. I have a few questions.

1. Why does connection event length include 'standby'? What is it?
2. If HF clock is already enabled, will it reduce the connection length by the time of the crystal ramp-up?
3. Why does connection event length include postprocessing? Can post-processing overlap with the next connection event RX or TX operation?

A small related bug report:

nRF5340 has the wrong simulation when RX is set to some value instead of 0. Try to set it to 1, and you will see a massive increase in power consumption. The picture will show the correct char of power consumption. However, the report numbers will be wrong. If you integrate the power chart on the picture, you will see how different it is from the report number of the power consumption.

Hi

In the nRF5340 image you've uploaded here there is also one byte of RX payload that you have not included in the nRF52 image. Please make sure both test setups are using the same parameters when comparing results. If you set the nRF52832 to have 1 byte of RX payload as well you can see that the nRF5340 has a slightly lower total current consumption than the nRF52832:

Best regards,

Hi Simonr,

Both images are for nRF5340. You can understand it because of 512kb application RAM.

The issue is why an additional 1 RX byte changes the current from 450 to 773 micro Amper.
