I am trying to configure the most basic point-to-point Bluetooth IP network. I have two computers with the same model of USB Bluetooth (2.0, EDR, etc) dongle attached to them. I am running Ubuntu Jaunty on both computers. I do not have GUI (desktop) applications installed on them. Ubuntu Jaunty comes with bluez 4.32. All I want is the most simple possible configuration... the minimal amount of configuration necessary to be able to have applications one the computers interact using TCP/UDP/IP via Linux network devices. I do not care about forwarding packets to other hosts, or about encryption or authentication, etc; I am trying to start with the equivalent of connecting two ethernet cards. When I connect the Bluetooth dongle, I get a "pan0" linux network device on which I can perform commands like "ip link set ...", "ip addr add ...", etc. They all succeed and I can ping the local device address. Each computer can do this local interaction with the pan0 network device. I can also do "hcitool scan" to see the remote Bluetooth devices, and I can do "hcitool info", "l2ping", etc. The device advertises "PAN", "GN", etc, services, so I do not think it is a limitation of devices. So on each side I can see and interact with the local pan0 network device, and I can use the "hciconfig" and "hcitool" to get some degree of interaction between the two computers. But if I configure the pan0 devices as I would a regular network device, including adding ARP entries which have the layer2 address of the remote pan0, I cannot seem to get the IP layer of the Linux kernel to actually talk to the remote Bluetooth device using the Linux kernel network facilities. If I run "hcidump", I do not see anything happening if I try to ping the remote Bluetooth interface. Am I missing something simple? I am not having any luck finding how to do what seems like it should be trivial... plugin a Bluetooth dongle on each side and be able to send IP packets from one to the other using the Linux network devices. I am clueless about the details of Bluetooth protocols. If I cannot get the networking working this way, I would be willing to have the devices connected to each other as a serial port, and then just run ppp over that, although I have no idea how to do that, since I have never tried or looked into it. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
