Hi @pc, yes, the plans are there. We are working on it now, but I can't give you a date yet. If you want you can open up a new question in the forum and we will be happy to assist you with current measurements.

Hi. Are there plans to update this devzone.nordicsemi.com/.../ profiler calculation for the nRF52840? It would be nice to see the power impact of -840's 125kbps/500kbps LE Coded PHY and +8dBm max Tx power options too.

Hi,

Following up multiple notification per connection event inquiry above. When/Is it expected ?

Thanks

@Lakerno The tool shows only one packet per connection interval. It will be updated with multiple packets soon.

@xvhongpeng
You can use the PPK to measure this of course. The Online Power Profiler is meant for evaluation before you buy our product, and for those who don't have the PPK or similar lab equipment.

Your company provides the PPK, and why not use the PPK to measure this? Can the PPK make it?

Will there be updates for multiple packets per interval, DLE and RX events?

@bhagath Sorry, I've updated the link now.

The link to the "test setup for measurements using the dk" is not working. Can someone please direct me to the correct one.

Thanks Bhagath

Hi @Stian, Could you provide the specific parameters that should be modified in power profiling example code in order to follow this guide? Thank you.

@Lakerno Slave latency is a planned feature

@ahedin25 Have you seen this tutorial? devzone.nordicsemi.com/.../ You connect the power analyzer as if it was an ammeter. If you want to use the power analyzer as a voltage source as well, you will need to do modifications to the DK to isolate the nRF chip from the rest of the circuitry.

@Stian Please provide the instructions for measuring current with the power analyzer. These are not provided in the infocenter. Thank you.

@Stian, Thank you. Waiting for the update. Would it be possible to include the Slave latency in the calculation?

Based on my understanding, the TX payload in one connection interval can be 6 x 20= 120 bytes. How come only max 27 bytes are allowed for the power calculation tool?
