我看n1的dts里面还有蓝牙的部分内容

我用了这个，说是unknown device type or id ，不知道后面这几个该 ...

用modprobe加载一下btrtl、hci_uart试试，armbian-config里先把蓝牙软件安装了

都加载了，没什么用，我估计还是串口的问题，我昨天晚上在想，既然dtb是个二进制文件，安卓，ce，armbian又同属liunx，有没有可能把安卓的dtb直接拿过来用呢？

不行，这个问题无数人都这么想过。不同版本的内核dtb都基本不能互换，跨系统更不可能。

那就只能重新编译了。不知道这玩意儿是怎么写的，抄都无从下手。

我认输了！
离成功只有一步之遥，却实在迈不过去！
改dtb搞定了串口，也能和蓝牙芯片通信了，芯片型号也识别了，就是tm起不来！
