could you send me the picture of "Unavailable" ? I flashed the P9.0.0_2.0.0 images to the IMX8MM DDR evk SD card, doesn't have the same issue as yours, refer to the schematic and user guide, The BCM 1MW Wi-Fi/Bluetooth module is used on the i.MX 8M Mini EVK DDR4 Board.

You can see that wifi is OK, but BT doesn't show my device ID and can't find other device.

Besides, I tried to use command "rfkill" to open BT through debug port.

But It shows nos such command.

Is there any solution ?

Thanks.
