BG770A-GL EMUX mode

Hello,
In my project we use a microcontroller connected to a BG770A-GL chip to connect to LTE-M.
I put the modem in EMUX mode with the AT+EMUX command to try it out, but I cannot seem to get out of EMUX mode. How can I go back to normal AT mode ? The EMUX application note does not state the way to do so, and I tried to use the Multiplexer Close Down command, but no success.

Thanks in advance for your help.

Can you try β€œAT+EMUX=0” please,this command may get out of EMUX mode.
