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 .
