nRF52840 PDK for mesh network

[jav_ITI]

I would like to know if you can create a mesh network with nrf52840 preview DK? 

Would you have a problem with this board? 

currently, would a better option create a mesh network with nrf52832?

Thank you in advance.

Hi,

Our nRF5 SDK for Mesh supports both nRF52832 and nRF52840, and there are examples for both the pca10040 (nRF52832 DK) and the pca10056 (nRF52840 PDK) there. Is that what you are looking for?

Regards,
Terje

Hi,

It all depends on what you need for your use case.

For a short overview of mesh stacks and what they are suited for you can have a look at our Mesh networks explained blogpost, see the section named "Different flavours of mesh." I recommend reading the full blogpost for more on mesh in general.

For Thread there are many options for application layer, support for UDP and 6LoWPAN, higher throughput (compared to Bluetooth Mesh) and a limit of 32 routers. Thread is supported on nRF52840 only.

For Bluetooth Mesh you have one application layer with standardized mesh models (and the option to make your own), Bluetooth Mesh-only networking protocol, and lower throughput (compared to Thread). Bluetooth Mesh is supported on both nRF52832 and on nRF52840.

I suggest having a closer look at both technologies while keeping in mind what is important for your use case.
