RE: Power Consumption of Channel Sounding

Dear Elfving,

Thank you for reply.

The initiator also acknowledged that the power consumption was as shown in the screenshot.

If you want, I can do this myself, and try to use the PPK2 with two of our 54L15 DKs running our completely default CS samples, and give you the numbers they provide?

→If it's not too much trouble, could you please help me out? I don't have a PPK2, so I'd like to know the actual measurements.

Best Regards,

Riki

Hi Riki,

Unfortunately I do not think we have data about this available. One reason might be because the consumption would depend on multiple factors. Even if you set up CS the way you want using our SDK, I assume you might want to change out the CS algorithm we provide in the SDK, and that change might also make an impact.

With that said, I do have the impression that the consumption on the reflector side is minimal, and on the initiatior side it is similar to other BLE traffic for the period it is in use. This means that you can have a look at the online power profiler to get an estimate too. For more accurate numbers though, using the PPK2 on with your specifications and hardware would be best.

If you want, I can do this myself, and try to use the PPK2 with two of our 54L15 DKs running our completely default CS samples, and give you the numbers they provide? (note that we do have offerings with even lower consumption though).

Regards,

Elfving
