No problem 🙂

Please let us know if there is anything else!

Ok, I will try the sample you mentioned.

Thank you again for your help!

Yeah I think that solution would be more Zephyr specific, so it makes sense that it requires CONFIG_BT_LL_SW_SPLIT as that selects the Zephyr controller.

I would rather recommend the DTM or radio test sample though. I do not know a lot about the Zephyr variant, but don't see any reason why that would be any better. DTM should work fine with any device that supports instruction communication over 2-wire. This previous case seems to go over the same topic (DTM with CMW270), have a look at the answers there.

Edit: I guess not everything in that case I linked would be interesting. I was mainly thinking of this post by Kaja.

hi Elfving

Thank you very much for your reply!

I saw that my current configuration showed a lack of dependencies, so I went further to find a relationship between them.

I found that when I added the following configuration to the prj.conf file, CONFIG_BT_CTLR_DTM_HCI=y worked successfully:

CONFIG_BT_LL_SW_SPLIT=y
CONFIG_BT_LL_SW_LLCP=y

After this, you can now communicate with nrf5340 normally through the serial port, and you can also successfully connect with the integrated detector CMW270.

May i ask that if this operation is reasonable, or how it is different from the sample you mentioned?

Regards,

David

Hell David,

BT_CTLR_DTM_HCI_SUPPORT is not directly user-configurable. You can find an overview over the configurations you can use here.

We do have a DTM sample though, as well as a radio test sample.
