Hi Team,
we are using two nRF5340 Audio DK kits to test LE Audio CIS example (unicast client & server).
kit1 nRF5340 Audio DK - act as gateway ( connected to PC/shared usb audio )
kit2 nRF5340 Audio DK - act as headset ( earphone)
after power ON kit1 , I did not see the LED1 (blue) blinking.
I see following logs printing security failure messages on client side. kindly help on getting CIS mode working on two audio kits.
