蓝牙Bluetooth: hci0 command tx timeout
各位好!在调试调试8723bs的BT功能,系统是linux3.4,先出现下面的的问题:
[root@test ~]$ echo 1 > /proc/net/rtl8723bs/wlan0/btcoex_dbg
[root@test ~]$
[root@test ~]$ hciattach -s 115200 /dev/ttySAK1 rtk_h5

备注:调试工具移植的是bluez-4.9,上面是加载了厂家提供的config和fw固件的打印信息,我现在的困惑是:“ lmp_version is 2300, project_id is 8723, does not match”和“tx timeout”是什么原因导致的?
