配置 GPS 设备，修改 /etc/default/gpsd 配置文件

	 
root@homeassistant:~# cat /etc/default/gpsd 
# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES="/dev/ttyACM0"

# Other options you want to pass to gpsd
GPSD_OPTIONS=""

# Automatically hot add/remove USB GPS devices via gpsdctl
USBAUTO="true"
	
		

默认 gpds 开启 ipv6，有些系统已经禁用了ipv6，就会出现下面的错误

屏蔽 #ListenStream=[::1]:2947 这行
