Project 14: Bluetooth Wireless Communication
(1)Project Introduction
The Micro: Bit main board comes with a nRF52833 processor (with a
built-in BLE(Bluetooth Low Energy) device Bluetooth 5.1 ) and a 2.4GHz
antenna for Bluetooth wireless communication and 2.4GHz wireless
communication. With the help of them, the board is able to communicate
with a variety of Bluetooth devices, including smart phones and tablets.
In this project, we mainly concentrate on the Bluetooth wireless
communication function of this main board. Linked with Bluetooth, it can
transmit code or signals. To this end, we should connect an Apple device (a
phone or an iPad) to the board.
Since setting up Android phones to achieve wireless transmission is similar
to that of Apple devices, no need to illustrate again.
