imx8: bluetooth audio streaming to imx8mq-evk output has intermediate noise

Hi,

Thanks!

imx8mq-evk connected with Android mobile via Bluetooth. Audio streaming happening from android to imx8mq-evk. Could hear music on 3.5mm jack but intermediate noise is also there. Trying to remove the noise, trying to attach device with baud rate but its failing.

Used hciattach command: "hciattach /dev/ttymxc2 qualcomm"

Trying to add baud rate with command but its failing, here is the command: "hciattach /dev/ttymxc2 qualcomm 3000000"

logs:

imx8mqevk:/home# hciattach /dev/ttymxc2 qualcomm 3000000
Qualcomm module LMP version : 0x07
Qualcomm module LMP sub-version : 0x025a
Opening firmware file: /etc/firmware/6.03.0_0602.bin
Could not open firmware file /etc/firmware/6.03.0_0602.bin: No such file or directory (2).
Setting TTY to N_HCI line discipline

Can you suggest solution for removing noise or anything on baud rate issue?

Target: imx8mq-evk

BSP: 5.4

Host: ubuntu16.04

Hi vsuneja63

 

there are several android releases with "BSP: 5.4", may be recommended to try

latest ones (please read Release Notes document which particular bluetooth chip is supported)
