Question

如何在RaspberryPi v4上重置蓝牙适配器？重设将重设大部分但并非全部设置。示例名称未更改。

pi@raspberrypi:~/ $ sudo hciconfig hci0 name
hci0:   Type: Primary  Bus: UART
        BD Address: DC:A6:32:02:12:1B  ACL MTU: 1021:8  SCO MTU: 64:1
        Name: 'raspberrypi'
pi@raspberrypi:~/ $ sudo hciconfig hci0 name rpi
pi@raspberrypi:~/ $ sudo hciconfig hci0 reset
pi@raspberrypi:~/$ sudo hciconfig hci0 name
hci0:   Type: Primary  Bus: UART
        BD Address: DC:A6:32:02:12:1B  ACL MTU: 1021:8  SCO MTU: 64:1
        Name: 'rpi'

期望名称从“ rpi”改回“ raspberrypi”

您还必须结合适配器重置服务：

sudo hciconfig hci0 reset
sudo invoke-rc.d bluetooth restart

如何在不拔下USB或重启的情况下在Linux上重置Bluetooth-adapter？
