In the i.MX8 Mini EVK which just bought without doing anything, and using your OS which had already burn in the NAND FLASH.

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.

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

But It shows nos such command.

Is there any solution ?

Thanks.

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