Bluetooth LE on iMZ series?

Hi,

Zebra support team send me a command to send to the printer in order to be sure that my printer iMZ320 will work as Classic rather than Low Energy.

I tried to send the following command: ! U1 setvar "bluetooth.le.controller_mode" "classic"

But when I send the command : ! U1 getvar "bluetooth.le.controller_mode"

Nothing happend, there is no reply from the printer.

Is this functionnality of Low Energy available on iMZ series?

Moreover I got the same result whan I tried to send the following command: ! U1 setvar "bluetooth.afh_mode" "on"

Thaks for your help
