Hi yenchao,

Is your WiFi/BT module connected on M.2 Key E while BT is used through UART-B interface?

I would suggest configuring pinmux spreadsheet to update the pinmux dtsi to be loaded in MB1.

Have you tried adding dma related property for 3110000.serial to run with DMA mode instead of PIO mode?

Please measure UART0 RTS via oscilloscope and verify BT requirements with the vendor.
