Setting public key for provisioning in Mesh Shell example

[shreyas.g]

Hello Community,

I am trying to provision a mesh node into the network using zephyr / ncs' mesh shell example. I am able to provision and control the nodes which do not use static oob- public key provisioning. But I cannot provision a mesh node which has secure provisioning enabled (according to Bluetooth Mesh SIG's recommendation) 

I also tried setting the value via `bt_mesh_prov_remote_pub_key_set` as mentioned in the link. Here is my log

bt_mesh_provisioner.bt_mesh_pb_adv_open: Provisioning XXXX

Provisioning link closed on PB-ADV

Am I configuring incorrectly or missing any steps here? It would be great if we have an example for this. 

My system configuration:

NCS: 1.5.1 / 1.5.99 (Tested on both)

Zephyr: 2.49

NRF52840

Thanks!

I was able to trace the problem back to setting static-oob function, which doesn't actually set the provisioning method to AUTH_METHOD_STATIC. After manually setting this flag, the provisioning completes successfully.
