典型蓝牙0.7-2.1 Mb/s,目前蓝牙4.0支持高速蓝牙,传输性能跟wifi差不多
ps:使用高速模式的时候不能够向下兼容,只能和蓝牙4.0对等传输 |

很久以前黑莓和苹果被很多人骂不能用蓝牙传文件。。。

第一次接触蓝牙是NOKIA的S40.那时候就是用来传歌的,大概20K左右的速度。

对了,无线键盘鼠标用蓝牙很渣,耳机用蓝牙也好不到哪去啊。。

@huangyan9188 不要乱说,蓝牙4.0最靠谱的传输方式一次只能发20个字节哪来的高速?

@andychen20121130 Bluetooth 4.0 promises speeds similar to Bluetooth 3.0 of up to 25Mbps. Both Bluetooth 4.0 and Wi-Fi Direct use the 802.11 networking standard to reach their maximum speeds.

@huangyan9188 我再给你补上完整的,咱不能断章取义。
Bluetooth 4.0 vs. Wi-Fi Direct: Speed Wi-Fi Direct promises device-to-device transfer speeds of up to 250Mbps, while Bluetooth 4.0 promises speeds similar to Bluetooth 3.0 of up to 25Mbps. Both Bluetooth 4.0 and Wi-Fi Direct use the 802.11 networking standard to reach their maximum speeds. But whether Bluetooth or Wi-Fi Direct speeds will run as fast as promised in the real world remains to be seen. In other words, don't believe the hype and keep an eye on independent data speed tests to see how each specification performs. but才是重点。 |

aheadlead OP @andychen20121130 我想起了USB 2.0 480Mbps~
