No, Certificate-based Provisioning is not a subset of static OOB provisioning. See this document: https://www.bluetooth.com/bluetooth-certificate-based-provisioning-a-technical-overview/.

Please keep further questions on this topic on your case.

Simonr Is certificate-based provisioning a subset of static OOB provisioning? How to enable it? There are two variables *public_key_be; *private_key_be; that need to be passed but as I have generated a private key using PSA crypto I am not able to pass the actual private key to this variable as I only have the key handler of private key

Okay, so to do static OOB procisoing, you have to initialize these two members of structure: https://github.com/zephyrproject-rtos/zephyr/blob/main/include/zephyr/bluetooth/mesh/main.h#L146-L149 with your desired values.

There are also examples of usage here and here where the last one is a good place to start to figure out how any OOB works, since test checks all of them.

For the AppKey binding. We're assuming you're asking about the provisioner here, right?

See the following for reference:

First add appkey to remote node. Like this.
Then find out models that you want to bind this app key to and then bind it like this (for SIG models). For vendor models it is very similar and shown few lines below in that code.

Best regards,

Simon

Hi Jayant

I've forwarded this internally, but the samples probably won't be made over night. It's also worth to note that the only true secure provisioning method is OOB with a public key, just as a side note.

Best regards,

Simon

Hi,

The default `bt_mesh_dk_prov_init()` function returns a structure, which does not contain the `static_val` member variables in `struct bt_mesh_prov`.

When provision the device to AliGenie Platform. It requires us to use the static OOB. The static OOB value is calculated by SHA256.

The value itself is not important. The problem is that we don't have an example shows how to initial the Mesh stack with static OOB.

By the way. I also need an example shows how to bind AppKey. The MESH examples in NCS are too simple.

Thank you very much.

Best regards,

Jayant

The Bluetooth Mesh: Light dimmer and scene selector sample for example is handled by the DK provisioning handler for DKs and supports OOB authentications from what I can tell. Let me know if this isn't what you're looking for. Most samples in the NCS depends on the nRF Mesh app to do provisioning.

Best regards,

Simon
