The PAN profile defines how to enable Bluetooth devices to participate in a personal area network.

One of the roles in PAN profile is a Network Access Point (NAP) that provides an Ethernet bridge to support network services to the PAN user. Read about it here: PAN specification.

For now I will try to simulate connection to a NAP from my phone. Why simulate? Because to achieve the real connection I need realization of BNEP protocol class which will transmit Ethernet payloads via Bluetooth.

Since Bluetooth can be eavesdropped in on, we want to use SSL as David said here in comments.

So the goal for now is to connect to some server using secure internet connection on my phone.

I chose the www.mozilla.org SSLv3 site as a server to connect to.

I found the CSecureSocket example at symbian.com/.../v9.2docs/.../ but not everything went of smoothly rather the connection was not established and system was completed with panics.

It seems that that example is pretty old even not for 3^rd edition. But I can’t assert so.

However I scoped the similar problems and documents over here and here.

When got tangled I used some parts of S60v3 Chat code example with insecure internet connection.

The “guiSetBluspan” application that was initiated at previous posts looks like this now:

you need to click “Options” menu then pick “Connect/Disconnect” item and then pick “NAP” item.

Diagram 1 – Connecting from application

After some seconds server will send SSL certificate. You need answer “Continue”.

Diagram 2 – Certificate question

After all steps of connection, handshaking, page request, getting server response and closing connection the notification will appear about successful operation.

Diagram 3 – Connection finished

The objects of these routines were to establish connection to secure HTTPS connection where NAP’s authorization page will be.

At next researches I need to connect to NAP server, provide user’s login and password. NAP is connected to Radius server which will verify user existence and will start accounting on him.

The source codes of application above are provided by this link: guiSetBluspan Zip archive v 0.003 (Nokia’s wiki)

See this posts here to know how to use sources.

The Secure Connection engine in focused in /Core/ folder and is called from “guiSetBluspanSettingItemListView.cpp”
