My box is some custom model board from Geniatech sold in Portugal as TBee. Using the Nexbox A95X which also has a QCA9377 chip I get Bluetooth disabled by default, by activating the Bluetooth I get the "No Bluetooth adapter found" message again, but the dmesg is different
The Nexbox A95X device-tree doesn't have any references to WiFi or BT devices. WiFi gets found since it's attached to SDIO which is described and acts like a bus with connected devices, but BT is a serial device that needs to be explicitly described with device type or the kernel doesn't know what to probe for.
Please boot https://chewitt.libreelec.tv/testing/LibreE…85.0-box.img.gz - I've added an experimental device-tree for the box that should get BT working.
