This allows us to gather information about whether a device
supports BR/EDR, BLE, or both. It appears as DBus Property
"Type" on the org.bluez.Device1 interface.
This is tested with the following steps:
Scan for devices and request the type property of a specific remote device,
using:
# dbus-send --print-reply --system --dest=org.bluez <obj path> \
org.freedesktop.DBus.Properties.Get \
string:org.bluez.Device1 string:Type
or request the type of all remote devices, using:
# dbus-send --print-reply --system --dest=org.bluez / \
org.freedesktop.DBus.ObjectManager.GetManagedObjects | \
grep -B1 -A2 Type
and check for "BR/EDR", "LE", and "DUAL"
