Bluetooth on i.MX8MP

[wanggg]

Hello, Expert,

I am testing the AW-CM358SM on the IMX8MP. The WiFi is working successfully, but when I test Bluetooth on UART3, it shows an error. The error message is as follows. I have tried many methods but still have not succeeded. Do you have any ideas on how to fix it? I would greatly appreciate your help.

error log:
