I have a proposal on how to fix Bluetooth noise. In my case works flawlessly.
The solution:
ZiShan, propose to place the black antenna far away from the 9038IC and battery.
My theory (to be verified by other users) is that: the distance between DAC and antenna doesn't matter. The interference between the concentric wire and the antenna is more important in that issue. The concentric wire terminals (or rather a lack of terminals
lets to another dipole forming. It is essential to keep all dipole sources aligned parallel, so it is much better if the antenna is placed, as illustrated above.
