How to TCP/IP over BNEP/PAN (Personal Area Network)

[jruiz]

Hi,

I'm trying to create to create A TCP/IP connection over Bluetooth between an n51x chip and other device (let say an iPhone mobile).

I've seen in the SoftDevice S130 description that "S130 is ideally suited to Bluetooth Smart Personal Area Network (PAN) hubs" I wonder if the API could help me to build an TCP/IP PAN network.

I know that to get IP we need BNEP which encapsulates ethernet frames in a L2CAP session,

Wikipedia explains it much better than me so I will stealth their description: "BNEP is used for delivering network packets on top of L2CAP. This protocol is used by the personal area networking (PAN) profile. BNEP performs a similar function to Subnetwork Access Protocol (SNAP) in Wireless LAN. In the protocol stack, BNEP is bound to L2CAP"

I can see that there're functions referring L2CAP in the softdevice API but haven't seen nothing about BNEP or PAN.

Thanks

@Jruiz: BLE is a PAN network.

Could you describe in more detail what you want to create ? When you say you want to create a PAN, what exactly you want to make ?

hi @hungbui, I would like to connect mobile and the nrf51-dk via Bluetooth and then create create a personal area network assigning each device a local IP.

for instance, something similar of what it's being done in this example www.ehow.com/how_7672801_connect-iphone-bluetooth-pan.html, in our case the nrf51-DK will take the role of the computer.

Thanks

There is nothing like that for BLE. The one in the link is for Bluetooth classic. Please focus on your application, and study a little bit more about BLE.

6LOWPAN would be the alternative to create that local network over BLE, but if what you want is to connect to a mobile seems that iOS/android haven't got it implemented yet even when the first of them is ussing already bluetooth 4.2

I don't really understand what you want to say above. Be very specific about the "PAN" you are looking for. You can always connect your device to the phone using BLE. And you can connect several devices together to create a PAN network of your own.
