During the use of the wireless module, various situations will be encountered. The most fearful thing is that the wireless module cannot work normally. If the wireless module fails to work properly, Chanste recommends that you consult the manufacturer first to see if there is a solution. someone will ask? Why do we need to consult the manufacturer first? Instead of sending it straight back to the manufacturer for repairs? First, it takes a long time to send the wireless module back to the manufacturer for repair, which will lead to a longer delay in the project. Second, according to Chanste's experience, there are many wireless modules sent back by customers, which are actually very small problems. As long as you consult the manufacturer, you can get a solution, which can also reduce the project stagnation time.

So how do we judge whether the unnecessary module is broken? Chanste sorted out several common symptoms, hoping to help everyone.

1. Wireless module power supply problem
The power problem of the wireless module is often encountered. When encountering a power problem, first check whether the red and blue lights of the wireless module are flashing normally. If they flash normally, it means the module can work normally; if the red and blue lights of the wireless module are not normal If it blinks, check whether the power supply is correctly connected, whether the power interface is loose, and whether the power supply can drive the wireless module to work normally. If there is no problem with the power supply and the red and blue lights cannot flash normally, it can be judged that the wireless module is damaged. Return to the manufacturer for repair.

2. The wireless module does not work properly
The wireless module does not work normally because the module cannot transmit data. In this case, we can reset it first. After reset, we can see whether the red and blue of the wireless module flash normally three times (because the receiving and transmitting signal lights of each manufacturer are inconsistent, it is for reference only). After the red and blue lights are reset, they normally flash three times and then go silent, which means that the wireless module resumes data transmission and can continue to work normally (the signal lights will flash normally when transmitting and receiving); if the red and blue lights of the wireless module keep flashing after reset , it means that the wireless module has not returned to normal work, and we will carry out the next inspection.

First, check whether the maximum transmission distance of the wireless module is exceeded. If so, we first check whether the wireless module can communicate at close range. If it can communicate, it means that the wireless module is good. Otherwise, it can be judged that the module is damaged; if the wireless module does not exceed the maximum transmission distance For the transmission distance, we need to check whether the antenna is damaged, whether the antenna interface is loose, and whether the placement position is correct (you can consult the manufacturer for the placement of the antenna).
There is also a situation, when our hardware equipment is in good condition, the wireless module cannot work normally. At this time, we need to check whether there are strong interference sources in the surrounding environment (interference sources include: signal jammers, buildings, metals, etc. ). In the case of the interference source, we recommend avoiding the interference source. If it is unavoidable, you need to consult the manufacturer to see if there is a specific solution.

If you need to buy a new wireless control module, Chanste is a trusted choice.
