[Android phone - Nanopi Air Bluetooth connection]

Hello,

 

   I am trying to connect an Android Phone in order to my NanoPi Air in order to be able to have access via IP (ssh, webserver...).

 

I set a bridge to share different BT connections:

 

brctl addbr pan0
brctl setfd pan0 0
brctl stp pan0 off
ifconfig pan0 192.168.42.1 netmask 255.255.255.0
ip link set up dev pan0

I register auth agent:

 

bt-agent -c NoInputNoOutput

I register network NAP agent:

 

bt-network -s nap pan0

I am able to connect but when I try to enable "Internet access" into my Android phone it fails. I can see in syslog log:

 

Apr  2 16:26:28 localhost bluetoothd[2960]: bnep: Can't add bnep0 to the bridge pan0: Invalid argument(22)
Apr  2 16:26:28 localhost bluetoothd[2960]: BNEP server cannot be added
Apr  2 16:26:29 localhost NetworkManager[449]: <info>  [1522686389.0133] devices added (path: /sys/devices/platform/uart.3/tty/ttyS3/hci0/hci0:12/net/bnep0, iface: bnep0)
Apr  2 16:26:29 localhost NetworkManager[449]: <info>  [1522686389.0136] device added (path: /sys/devices/platform/uart.3/tty/ttyS3/hci0/hci0:12/net/bnep0, iface: bnep0): no ifupdown configuration found.
Apr  2 16:26:29 localhost NetworkManager[449]: <info>  [1522686389.0371] devices removed (path: /sys/devices/platform/uart.3/tty/ttyS3/hci0/hci0:12/net/bnep0, iface: bnep0)

 

It seems to fail when NanoPi tries to add bnep0 to pan0 bridge but I don't know why. Any idea?

Yes, I saw how to add custom packages but not how to avoid some of them get installed during chroot creation...

Hello,

 

   I am trying to build a custom Armbian image and I would like to remove some deb packages in order to not to be installed. ¿What would be the right place to do that?

 

Thank you!!

[Has anybody a good latency after the RT-PREEMPT patch?]

Anyone knows which is the right RT path for mainline 4.14.y kernel? I am trying to patch it for orangepizero (sunxi-next patches folder) but both, patch-4.13.10-rt3.patch included one and patch-4.14.12-rt10.patch downloaded fail.
