After a whole afternoon the sweating like a bull, I find how to fix that issue
I ask help to Singular sound Support and they answer me kindly this, but that’s not fix the issue :
Getting the Maestro to communicate with phone is done in a different way, please make the MM be “forgotten” from your BT list (remove it from the list) and then follow these instructions:
- Hold down pairing button on the back of the Maestro.
- Execute action on MM app (firmware upgrade, or programming device etc)
Note: DO NOT manually pair on phone’s Bluetooth list, it will show BLE CONNECTED on Maestro screen once an action is taken from app while pairing light on Maestro is blinking.
Let me know if this does not work. Thank you.
NO it’s not working because you forget one thing that you can find in this video .
