Platform: IMX8M-Mini

OS: Android 9 (p9.0.0-1.0.0_ga bsp)

WiFi module: QCA9377

Issue description:

basically, the bluetooth works fine but the speed is fixed on 115200bps, I already tweaked the HAL layer (hardware/qcom/bt/) and force to config the uart baud rate as 3Mbps as following link, but still the same results.

I also trying to change firmware and modify serial driver of linux kernel but no any improvement...Do you know how to improve it or recommend suitable people to me, I need helps with directions.
