How can I set up a bluetooth PAN connection with a Raspberry Pi and an iPod?

Question

I have tried following this tutorial: How to enable PAN on Raspberry

When I try this command:

sudo pand –connect xx:xx:xx:xx:xx:xx -n 

I get the error:

pand[4035]: Bluetooth PAN daemon version 4.99 
pand[4035]: Connecting to xx:xx:xx:xx:xx:xx
pand[4035]: Connect to xx:xx:xx:xx:xx:xx failed. Connection refused(111)

I have tried the following so my iPod is trusted by my Raspberry Pi.

> sudo bluez-test-device trust xx:xx:xx:xx:xx:xx yes

Any help on this topic would be greatly appreciated.

Here's how you can setup a bluetooth pan on Raspbian.

This answer uses systemd/networkd but you could do something similar with an interfaces file and dnsmasq if you wanted.

Run:

sudo apt-get install bluez-tools

Create the following files:

/etc/systemd/network/pan0.netdev

[NetDev]
Name=pan0
Kind=bridge

/etc/systemd/network/pan0.network

[Match]
Name=pan0

[Network]
Address=172.20.1.1/24
DHCPServer=yes

/etc/systemd/system/bt-agent.service

[Unit]
Description=Bluetooth Auth Agent

[Service]
ExecStart=/usr/bin/bt-agent -c NoInputNoOutput
Type=simple

[Install]
WantedBy=multi-user.target

/etc/systemd/system/bt-network.service

[Unit]
Description=Bluetooth NEP PAN
After=pan0.network

[Service]
ExecStart=/usr/bin/bt-network -s nap pan0
Type=simple

[Install]
WantedBy=multi-user.target

Then run

sudo systemctl enable systemd-networkd
sudo systemctl enable bt-agent
sudo systemctl enable bt-network
sudo systemctl start systemd-networkd
sudo systemctl start bt-agent
sudo systemctl start bt-network

Finally to pair, run:

sudo bt-adapter --set Discoverable 1

Then, on the other device pair it and connect the network. Hopefully everything should just work after that.

Also note: currently, if you are running Raspbian Stretch, you will need an updated btuart script to workaround the issue here.
