Dear all ,
I am working on a prototype board which has a TMS320C5515 processor interfaced with Bluetooth module(PAN1325A) and having audio codec chip TLV320AIC3254 . When I try to stream audio over Bluetooth , I am able to listen to a motor running kind of noise (sound clip attached for reference) on the Bluetooth headset . But this noise is not present when Bluetooth is turned off and the same clip is heard over the wired headphone out of the same codec IC . It was initially suspected that the noise might be caused due to improper shielding and this was taken care by ensuring proper shielding on our board. But this issue still persists.
Thanks in advance
