Hi,

But note that the latest SDK does not have support for any SoftDevice approved for the nRF52810:

Hi Cédric,

That sounds like a good plan. nRF52810 is a fair choice as well, note that it supports slightly different softdevices than nRF52811 as well, allowing more flexibility on choosing one that is right for you. We always recommend using the latest one (that is supported for the respective IC) to make sure you get the latest features and bug fixes.

Best regards,

Andreas

I understand. I'll study then nRF52810 which might fit our needs. I'll study it with SW team and I let you know if I have further question. I thank you very much for your support

Regards,

Cédric

Hi,

As awneil points out, both are very much their own products, none should be considered a development chip, they just have different feature sets and pricing. nRF52832 DK is used for SW development on nRF52810 though, and nRF52840 DK is used for development on nRF52811.

Note that nRF52832 and NRF52811 does not support the same SD versions. nRF52811 supports S112, which requires less flash, but has a limited feature set compared to S132 which is supported to nRF52832. This might allow you to squeeze by the flash available.

nRF52832 HW does not support the DF features in BT 5.1, only nRF52811 does, but note that there is no SW support for this yet. If you do not plan to use this though then there might not be too much sacrifice going with nRF52832.

Best regards,

Andreas

Certainly not!

AIUI, nRF52832 is main-stream; the nRF52811 is a "stripped-down" version for simple, low-cost projects.

EDIT

Sorry - I was thinking nRF52810!

[quote userid="24823" url="~/f/nordic-q-a/46847/nrf52832-features-and-bulk-size-flash-ram-for-stack-versus-nrf52811"]Is the stack optimized as on the nRF52811 [/quote]

I doubt it: nRF52811 is very new - there are many posts noting the lack of support for any of its new features beyond what's in the existing products...

😞
