Using a LEDE router as the gateway

Requirements:

Gateway has IPv6 Access

USB BLE Dongle or on board

Device with LEDE-project firmware and USB port if no BLE support onboard.

Comfort with command line.

Connect with SSH and run

```

opkg update
opkg install kmod-bluetooth kmod-bluetooth_6lowpan bluez-libs bluez-utils kmod-usb-core kmod-usb-ohci kmod-usb2 radvd

reboot

```

Reconnect

```

modprobe bluetooth_6lowpan

mount -t debugfs none /sys/kernel/debug

echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm

hcitool lescan

```

echo "connect 00:11:22:33:44:55 1" > /sys/kernel/debug/bluetooth/6lowpan_control

where 00:11:22:33:44:55 is the MAC address of your UmbrellaMod

Distributing routable IPv6 prefix

To configure RADVD create /etc/radvd.conf file and paste the following contents:

interface bt0
{
    AdvSendAdvert on;
    prefix 2001:db8::/64
    {
        AdvOnLink off;
        AdvAutonomous on;
        AdvRouterAddr on;
    };
};

Next, start RADVD daemon:

# Set IPv6 forwarding (must be present).
sudo echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
# Run radvd daemon.
sudo service radvd restart

If successfull then the UmbrellaMod connected to the host will receive a routable 2001:db8 prefix.

This can be verified by sending echo request to the full address:

ping6 -I bt0 2001:db8::2aa:bbff:fexx:yyzz

where aa:bbff:fexx:yyzz is device Bluetooth address.
