Module HC06 and mBlock v3


I’m trying to use too a HC-06 bluetooth modules for a Arduino Uno.
I changed the baud rate to 115200 with AT commands.
I pair the HC06 module and my computer. It’ OK. And next I connect the Arduino board to mBlock software by bluetooth module.
But I can do nothing. The point of the Arduino extension turns green.

Did you receive information ?

Thank you for your help.

Do you aware the HC-06 is running at 3.3v for the signal exchange, but mBlock is running at 5V
