Can I create project Open Thread for nrf52811 from nrf52840 platform ?

Hi all,  I am working with NRF52840 and Open Thread SDK V3.1. Everything is normal.

But now, I want to run open thread example in SDK with NRF52811. To reduce product costs.

But I don't find any example available in SDK v3.1.

So I think I will have to create project for nrf52811 by myself.

I find one example for it but not use ide. It at : https://github.com/openthread/openthread/tree/master/examples/platforms/nrf52811.

Can I convert project from nrf52840 for nrf52811.

So, can you give me a tutorial for make this ? 

And question 2 : I read about to nrf52811 

"Because of the memory constraints, multiprotocol features are not supported when using nRF52811. For this reason, the SoftDevice is not used. Moreover, the support for Joiner and Commissioner in nRF52811 is not available through the regular SoC architecture, but it is possible in the RCP mode."

This  mean I can't put this chip join to thread network by application Openthread in Smarthome. It have to join thread network by itseft ? And I have to tranfer master key and panid for it ? 

And It can't help other Joiner to thread network because it don't have commissioner feature.

Please explain for me ?

Thank very much !!

  • Hi.

    Can I convert project from nrf52840 for nrf52811.

     Can you take a look at this user guide?

     The point of nRF52811 is that the low cost and low resources means that it's not suppose to be a joiner. You can't use the standard thread commissioning, to make it join a Thread network you have to hardcode in the credential (the binary you flash already has a panid, masterkey, channel, and so on set). It also does not support commissioner for the same reason.

  • Thank for reply,

    I want to ask some question.

    In SDK Thread v3.1, Can I convert all example from nrf52840 to nrf52811 and run normal ? All example ? Because I need convert thread mqttsn and coap.

    I don't want to hardcode, The product does not allow that. So Can I tranfer information via bluetooth to nrf52811. Then, I disable bluetooth and run thread ?

    Please tell me a answer.

    Thank !!

  • Hi again.

    It's not possible on nRF52811, the chip has not enough resources. If you don't want to hardcode it you have to use a bigger chip.

    The nRF52811 is designed to be an RCP device.

    Best regards,

    Andreas
