For my first Nerves project, I would like to create a Phoenix application that would be available only via Bluetooth Personal Area Network (PAN).

I’ve never done this before, but from what I could understand it would be feasible.

During my researches, I came across this stackoverflow post explaining in detail how to setup a Bluetooth PAN on Raspbian.

So I tried to reproduce the steps for Nerves :

• First, I created a new system based on nerves_system_rpi3
• On this system I installed bluez-tools and bluez-utils packages
• I’ve also activated the Bluetooth subsystem support in make linux-menuconfig → Networking Support

Once the firmware burn on my SD card and the Raspberry started, I executed the following commands :

# Run D-Bus & Bluetoothd daemons
mkdir -p /var/run/dbus
/usr/bin/dbus-daemon --system
/usr/libexec/bluetooth/bluetoothd &

# Create PAN interface
ip link add pan0 type bridge

# Configure interface
ifconfig pan0 192.168.50.1 netmask 255.255.255.0 up

Until then, no problem.
But when I tried to execute bt-agent -c NoInputNoOutput or bt-network -s nap pan0, I got the following error:

bt-agent: bluez service is not found
Did you forget to run bluetoothd?

However, when I display the list of processes, I can see bluetoothd running.

I would like to know if anyone has ever had this problem or if anyone has ever succeeded in setting up a Bluetooth PAN.

Thanks in advance.
