Dear NXP,

      I checked with different BT headset and some of the headset I found this problem.

Please find the below log,

This one again verified in headset side, This is the problem with headset side. At first time it will work because we press volume button continuously for connecting purpose. But, after second time/once connected we are not pressing volume button, So, in this case it will not work.

I Closed this thread now.
