bluetooth.le.controller_mode on iMZ

Hi,

I'm trying to check the current status of the Bluetooth Low Energy controller on my iMZ320 but I can't have the reply from the printer.

I tested to send ! U1 getvar "bluetooth"

This is working but there is no line about the bluetooth.le.controller_mode even if I click several time on "Send to printer"

Here is what I get:

bluetooth.

bluetooth.discoverable : on , Choices: on,off

bluetooth.version : 5.5.2

I tested the command ! U1 getvar "bluetooth.le.controller_mode" but the printer reply "?"

Could you help me with this issue??

Many thanks
