i bought the BTA30 pro and trying to play around it, i connected the BTA30 pro via USB from my laptop, put it in BT TX mode and connected my BT headphone which supports BT version 5.0. its a infinity glide N120. i played a song in my laptop and was able to listen to it in my earphone without issues. but the BT codec - its always blue ( SBC). when i try to change the codec to LDAC it doesnt change. infact it doesnt change to any codec except the default. i tried the same in BT RX mode and connected by mobile and played a song. the BT CODEC was Cyan in color and not able to change to any other codec - even though in the APP i have disabled all codecs except LDAC.
did you encounter any such issue?
