Request hexadecimal key (hex 16 octets)

[Meg]

Hello,

I am using the Light switch example for BLE meshing. I am trying to provision the nRF52832 with Raspberry Pi. I am unable to successfully provision because of the authentication step. 

Request hexadecimal key (hex 16 octets)
[[mesh-agent]# ] Enter key (hex number):

I would like to ask: How do i obtain this hex 16 octet key?

Hi Meg, 

Could you let me know which application you used on the R.PI to do provisioning ? 
What exactly the 16 octets key that you are trying to enter ? 
Note that in the light switch example we use the static authentication STATIC_AUTH_DATA. You can find it in example_common.h file.

Hello, 
Thank you very much for replying! 
I’m running meshctl through the R.Pi terminal so the steps are 

1. meshctl 

2. discover-unprovisioned on 

3. provision <device uuid> 

Then the provisioning is unsuccessful due to being unable to key in the 16 octet keys for the static authentication (OOB)

Is there a way to change the authentication to NONE? Or how do I get that 16 keys to authenticate my R.Pi connection to the nRF52832

Alright, I couldnt find the STATIC_AUTH_DATA in the example_common.h file for nrf5_SDK_for_Mesh_v4.2.0_src but i found it in the nrf5_SDK_for_Mesh_v3. 

So after I downloaded the light switch example for client onto my nRF52832, I provisioned through the R.Pi. I managed to successfully provision it. 

EDITED: The STATIC_AUTH_DATA is the same for nrf5_SDK_for_Mesh_v4.2.0_src
