La Otra Cuenta

Hello balbes150, I found problems when activating the UFW firewall in Armbian_5.34_S9xxx_Ubuntu_xenial_3.14.29_mate_20171104. Here is a list of the problems detected in the checkup, in case it helps to compile the kernel and include the necessary modifications for UFW to work properly. Thank you so much for the effort.

To enable BT. You need to perform two steps.
 
1. Add to /etc/modules to list the module
hci_uart
2. Add to the end of the initialization script (/boot/amlogics905x_init.sh) string
 
su -c 'hciattach /dev/ttyS1 any'
 
After a reboot should turn on BT.
