Hi, this is 6LoWPAN code for BT LE as described in http://tools.ietf.org/html/draft-ietf-6lowpan-btle-12 The code is not yet ready for prime time but is sent in order to get discussion started. The devices need to be setup manually in this version. This is implemented in patch 5. That patch is just a temporary one and will be eventually removed when the devices can discover the 6LoWPAN service automatically. Test usage: You have two devices with BlueZ 5 stack in them device1 00:11:22:33:44:55 device2 66:77:88:99:00:11 First add the desired devices manually into kernel root@device1# echo 66:77:88:99:00:11 > /sys/kernel/debug/bluetooth/hci0/ble6lowpan root@device2# echo 00:11:22:33:44:55 > /sys/kernel/debug/bluetooth/hci0/ble6lowpan then connect the devices root@device1# hciconfig hci0 leadv root@device2# hcitool lecc 00:11:22:33:44:55 if the connection is established, then you can send IPv6 packets between these two systems using the link local addresses root@device1# ping6 fe80::6477:88ff:fe99:0011 root@device2# ping6 fe80::211:22ff:fe33:4455 the ble6lowpan0 interface is created and routes to peer are automatically setup. By default 6LoWPAN connection is not established between devices, so you need to add the MAC addresses manually into the /sys/kernel/debug/bluetooth/hci0/ble6lowpan file. If you want to prevent further connections you can remove MAC address from the debugfs file like this echo "00:11:22:33:44:55 d" > /sys/kernel/debug/bluetooth/hci0/ble6lowpan Rebooting or unloading the bluetooth kernel module will also clear the settings from the kernel. Areas of improvement: - route setting could be done in user space - ARP type is set to IEEE802154 but the transferred packets are actually not that type - discovery of 6LoWPAN service needs be automatic - split patches more, especially number 2 is a bit too big Cheers, Jukka Jukka Rissanen (5): Bluetooth: Initial skeleton code for BT LE 6LoWPAN Bluetooth: Enable 6LoWPAN support for BT LE devices route: Exporting ip6_route_add() so that BLE 6LoWPAN can use it Bluetooth: Set route to peer for 6LoWPAN Bluetooth: Manually enable or disable 6lowpan between devices include/net/bluetooth/l2cap.h | 1 + net/bluetooth/Makefile | 2 +- net/bluetooth/ble_6lowpan.c | 1714 +++++++++++++++++++++++++++++++++++++++++ net/bluetooth/ble_6lowpan.h | 28 + net/bluetooth/hci_core.c | 4 + net/bluetooth/l2cap_core.c | 20 +- net/ipv6/route.c | 1 + 7 files changed, 1768 insertions(+), 2 deletions(-) create mode 100644 net/bluetooth/ble_6lowpan.c create mode 100644 net/bluetooth/ble_6lowpan.h -- 1.7.11.7 -- 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
