802.15.4 / Thread current consumption

[Kare]

Anyone done or seen current consumption measurements for the Thread SDK on nRF52840?

I need to understand relation with other technologies and other chipses on this, and I of course expect the nRF to be outstanding :) Numbers for routers with varying data amounts/nodes as well as for (sleepy) end devices would be really useful.

Hi,

Unfortunately, we don't have any data on current consumption in 802.15.4/Thread yet. The nRF52840 chips is only available in engineering samples, and the 802.15.4 MAC library and SDK for Thread is still experimental, and the results now will not necessary be identical with numbers of final chip and software. If you want to do current measurements yourself, I would recommend buying the nRF52840 PDK and the Power Profiler Kit which will show real-time current consumption of the device, making it easy to see current consumption in various modes.

Best regards,

Jørgen

Ok, Thanks, understood. Yes, I have the ppk - and also the excellent Otii PC software with it qoitech.com/ .

A number of PDKs would be needed and some iterations to complete the various roles/setups, but I will work to find a time slot for the testing :)

seeing that the mesh-sdk has now v1.0 status - is there any plans on having a production-ready thread-SDK anytime soon?

Production-ready version of Thread SDK will be released shortly after final version of nRF52840 IC is available, which should not be far away. Until the chip is final, there is no point in releasing a production-ready SDK. Please contact your regional sales manager for more details on releases.
