[rock 3a] Which tty connect to M.2 Key-E?

Hi All

I have M.2-JODY-W2 connected to rock 3a to work.
I could to connect WiFi with the NXP driver. Below are the build steps.

> sudo git clone http://source.codeaurora.org/external/imx/mwifiex.git -b lf-5.10.72-2.2.2
> git clone https://github.com/NXP/imx-firmware.git -b lf-5.10.72_2.2.0
> cd mwifiex/
> cd mxm_wifiex/
> cd wlan_src/
> make -j 4 KERNELDIR=/usr/src/rk3568-kernel5.10-alldrivers-ubuntu22.04-kernel5.10-rk3568-rock3a-alldrivers-beta3 CROSS_COMPILE=/usr/bin/ build

However, I tried to make bluetooth work, but I cann’t know which UART device it is and it is not working.
