Verifying whether device is a known device or not prior to connecting/pairing/bonding

[DG]

Dear Nordic Team,

We are working on a solution where we want to only connect to a certain device if it is a known device and not accept any random requests.

We believe the information stated on this link:  Simple Application-level Authentication  is very helpful but the code: ble_nus_ecb zip file is not the complete code.

Can you please provide the complete project or point us in the right direction where we can get the project?

Thanks

Ambimat Team.

Hi,

The project is attached to the Simple Application-level Authentication blog post in the end of the post in a zip archive called ble_nus_ecb.zip. Note that tis is for the old nRF5 SDK.

This is based on connections, though. I do not know enough about your requierments to be specific, but if for instance the peer device is a phopne, you will in practice have to connect and bond once first in order to obtain the Identity Resolving Key (IRK). This can subsequently be used to filter/whitelist this (and potentially other) devices and only allow connections from that. You can see an example of that in the Bluetooth: Peripheral Accept List sample.
