   BTW, to support the monolithic(profile plus l2cap/hci) bluetooth stack like zerphyr and nimBLE, the serial driver(/dev/tty*) is better interface. Here is how bluez and bluedroid work on Linux:
   
   1. bluez contain profile only, and talk with kernel l2cap/hci through socket
   2. bluedroid contain profile+l2cap+hci talk with kernel through /dev/tty*
   
   It's strange and complex to support bluedroid/nimBLE through the raw/managed bluetooth socket but bypass L2CAP/HCI layer.
