After downloading the Bluetooth remote control <\/span>APP<\/span>, we have to install it.<\/span><\/p>

(Note: If the phone prompts you to obtain location rights during installation, you need to click to <\/span><\/strong>“<\/span><\/strong>agree<\/span><\/strong>”<\/span><\/strong> to get location permissions.)<\/span><\/strong><\/p>

 <\/span><\/p>

2.<\/span><\/strong>Download code<\/span><\/strong><\/p>

Use the data cable to connect the micro:bit board to the <\/span>your <\/span>computer. At this point we can see a micro:bit drive letter in the computer.<\/span><\/p>

\"image.png\"\/ <\/span><\/strong><\/p>

Download the <\/span>【<\/span><\/span>Bluetooth Remote Control <\/span>code】<\/span><\/span> in the download area of this product, and then drag or drop the hex directly or send it to the micro:bi drive letter.<\/span><\/p>

! Note: We provide two hex files,<\/span><\/strong><\/p>

microbit-Buletooth_control.hex<\/span><\/strong> without ultrasonic display function,<\/span><\/strong><\/p>

The<\/span><\/strong> <\/span><\/strong>microbit-Bluetooth_control_with_Ultrasonic.hex<\/span><\/strong> <\/span><\/strong>is shown with an ultrasound display.<\/span><\/strong><\/p>

It is recommended that you use the former (without ultrasound display, the control is smoother)<\/span><\/strong><\/p>

<\/span><\/strong><\/p>

3.<\/span><\/strong>Connect Bluetooth<\/span><\/strong><\/p>

3.1 After the Bluetooth remote control <\/span>code<\/span> is downloaded, <\/span>open the <\/span>power<\/span> of<\/span> <\/span>the <\/span>Tiny-bit. At this point, you will see the pattern shown in Figure 3-1 on the LED dot matrix of the micro:bit board. The RGB <\/span>light will be <\/span>light<\/span>ed<\/span> up in red. It is the state that Bluetooth is not connected.<\/span><\/p>

3.3 <\/span>The phone will automatically connect to the Bluetooth near the car. If there is no automatic connection, you need to click<\/span> <\/span>【<\/span><\/span>CONNECT<\/span>】<\/span><\/span>on the APP interface.<\/span> As <\/span>shown in Figure 3-<\/span>3. <\/span>Then, Bluetooth can be successfully connected, and the APP will enter the interface as shown below.<\/span> <\/span>As <\/span>shown in Figure 3-<\/span>3.<\/span><\/p>

After the Bluetooth is connected successfully, the pattern shown in Figure 3-5 will be displayed on the dot matrix of the Tiny-bit, and then the green RGB <\/span>light <\/span>will be illuminated. <\/span>After waiting for the green RGB searchlight to be lit, we can start controlling the car.<\/span><\/strong><\/p>

If the Bluetooth is disconnected, a pattern of crying faces will appear on the dot matrix of the Tiny-bit car, as shown in Figure 3-6 below.<\/span><\/p>
