[Main control connection]
1. xLight doesn't run properly after I upload a program to it, why?
2.How do I turn off the xLight control box?
3. Does the control box support only the default LED strip?
4. I can't connect my xLight to the Internet through the mobile app, why?
5. How do I power on xLight?
6. After connecting xLight to mBlock 5, I wrote a program but haven't uploaded it to the control box. When I try to control the LED strip with my app and remote control, however, the LED strip doesn't respond, why?
1. I connect an LED strip to the xLight control box that I have connected to my computer, but the LEDs can't be lit up or the brightness is low, why?
2. Besides the acrylic boards delivered with xLight, I need more with other styles. How can I customize more acrylic boards?
3. With the default program, I use the remote control or the Makeblock app to control an LED strip/string, but not all the LEDs are lit up, why?
4. After I compile and execute a program, the LEDs of an LED strip/string are not lit up as expected, why?
You may have selected the wrong block category. The blocks designed for LED strips can't be used to program an LED string. For details, see step 6 in the "Connect xLight to mBlock 5" section in the user manual.
1. Why is the remote control delivered without a battery?
2. What is the model of button battery for the remote control, and where can I buy it?
The remote control uses a button lithium battery, the recommended model is CR2025 3V. You can also use other batteries of the same size. Button batteries are available in supermarkets or online malls.
3. How do I use xLight without a remote control?
For details, see the instructions in the user manual delivered with xLight.

[mBlock 5 extension]
1. After I add the xLight device extension on mBlock 5 and use blocks in the LED String category. When I set two of the RGB values to 255, some LEDs of the LED string are not lit up in the expected color, why?
The timing sequence in the RGB factory settings is unknown. A color with RGB values closer to the white light range (that is, two of the RGB values are 255, such as 255/255/255 and 247/247/247, and the brightness is higher than 30%) is more likely to change to yellow. Do not set RGB to such values, so that the LED string can work properly.
2. Why does it take so long to update the firmware on mBlock 5?
Due to the transmission quality and characteristics of MicroPython, the default baud rate is 115200, which is relatively low.
3. When I update the firmware of xLight on mBlock 5, the update is suddenly interrupted. Then I power on xLight again, but the control box doesn't respond, why?
The interruption causes the failure of firmware update. If firmware update fails, the control box can't work after being powered on. When this happens, update the firmware again.
