Transmitting data via Bluetooth... 70.46 K/s

On the last day of last year, I drank at noon and went to the fifth floor of Hailong in the afternoon to bring this cute little thing back to my house ......
We can see that this cute little blue tooth not only emits beautiful blue light, but also sends data from the blue light to the air, with a circumference radius of 15 meters. Cool.
Later, Gary Moore's full back to the blues was transferred from the computer's hard disk to the M2 card of Tom. Now, the USB data cable can be securely sleeping in the drawer. ^_^
