Why is Audio not listed?
You can get the TxPower (if lucky) from the device via DBUS Device1
Interface
dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX
org.freedesktop.DBus.Properties.Get string:org.bluez.Device1 string:TxPower
dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX
org.freedesktop.DBus.Properties.GetAll string:org.bluez.Device1
replace dev_XX_XX_XX_XX_XX_XX with your BT MAC
