today i update my bt11 to 1.0.9. Now it dont work any more.

• Cant select codecs in the app

• Cant pair devices

• Stuck and cannot be controlled via the app

If i try to pair headphones (which previously worked without any problems) it stuck at constantly blue LED (no flashing, just constantly blue)

In this condition the managing bluetooth device (iphone or ipad) loses the connection and i have to unplug the device (restart)

tried all the stuff like restart, diffrent device, delete pairing, delete bt11 in the app etc. Still the same, no function.

What can i do?
