I have a MAX10 device (rk3399, Android 10, with latest SW as of writing this post, i.e FW: HA3_rk3399_10.0_ota(20220824) , latest MTCE MCU 3.78).
My device can only connect to my phone and to OBD devices via Bluetooth but it is unable to detect other BT devices, like the BT LED strip in the car. Other non-phone and OBD devices are also not detected. It seems it is a limitation of the OS or the hardware. I am tending towards a limitation in the OS (driver issue probably?).
I have tried connecting an external BT dongle via USB, but without luck. If there is a workaround, could you advise me what kinf of USB BT Dongle might work?
I would appreciate any solutions!
