To match the requirements of the proposed commissioning process, the edge router has to implement the following functionality:

Scan for Bluetooth Smart devices.
Parse advertising packets and detect IPSP service and manufacturer specific data.
Match the SSID value of the advertising packet and the preconfigured one.
Connect to the Bluetooth Smart node that is advertising with the proper SSID.
Perform pairing with Passkey in order to authorize device joining.
Enable the 6LoWPAN Bluetooth Smart connection on L2CAP CoC level.

All of the above have been implemented in the example daemon called bluetooth_6lowpand, which is built along with the BlueZ package on the Linux based system.

The bluetooth_6lowpand daemon is released in a separate repository that you can find on Nordic's GitHub page. The daemon is supported on OpenWRT platforms with Chaos Calmer 15.05 and on Ubuntu systems with Linux Kernel ≥ 3.18.

To see an example of how this daemon can be used in combination with the nRF IoT Joiner Android application, see here.
