Hello All,
I am trying to setup a typical Bluez PAN server on an IMX8 Mini, NXP kernel version 4.19.35 and Bluez 5.54. Unfortunately, most of the tutorials for this involve the pand daemon, which was deprecated in Bluez 5. I realize that both of my kernel and Bluez versions are outdated. For internal reasons these are the versions I have to use.
My command list.
// Start the Bluetooth daemon
cd /usr/libexec/bluetooth
./bluetoothd -d &
// Enable the Network1 and NetworkServer1 D-bus interfaces in /etc/dbus-1/system.d/bluetooth.conf
dbus-send --system --dest=org.bluez /org/bluez/hci0 --type=method_call org.bluez.NetworkServer1.Register string:"nap" string:"tether"
// Create the network bridge that Bluez wants to see.
ip link add name tether type bridge
ip link set tether up
// Start the debug monitor
btmon &
// Launch the PAN server
bluetoothctl
power on
scan on
pairable on
discoverable on
discoverable-timeout 0
agent DisplayYesNo
default-agent
trust (my phone's BT address)
I am able to pair from an Android Smartphone. Upon trying to use the Bluetooth connection as an internet connection, I see ARP packets appear through btmon. The bnep0 interface never appears, however, and the following error message appears in the btmon printout:
= bluetoothd: bnep: Can't add bnep0 to the bridge tether: Invali.. 302.610684
= bluetoothd: BNEP server cannot be added 302.610724
Upon digging into this error, I found that it was emanating from a SIOCBRADDIF ioctl that was throwing error 22 (Invalid Argument). Has anyone had any luck setting up a basic PAN server on Bluez 5.5X?
