Frequently Asked Questions |
|
★Question:Using default parameters, with a requirement of over 4km, the customer has 12 modules with 5V power supply in open suburban areas, with a rated power output of 2A. The transmitting end is a suction cup antenna, and the receiving end is a rubber rod antenna, located 1.5-2 meters above the ground. The maximum power ripple is ± 15mv in multiple environmental tests, and it does not exceed 2km in all cases. Please help analyze how to increase the distance. Is there anything else that needs to be noted |
| Answer:If there is no adsorption, it is recommended to adsorb; There are two options: 1. Replace the transmitting antenna with TX433-XPH-300, 2. Try replacing the receiving antenna with TX433-JK-20, while the suction cup is attached to the iron sheet. |
| ★ Question: What's the reason why address configuration cannot include F, such as 15/31? |
| Answer:Fixed point mode, channel 1, addresses 15 or 31 or hexadecimal addresses with F can communicate. |
| ★Question:I used the matching tool software "RF Setting" to set the parameters of the module, but it has not been successful. The power has been added and the baud rate is 9600, 8N1. I am setting it in sleep mode (M0 and M1 are directly connected to 3.3V). Is there anything else I need to pay attention to? |
|
Answer:Is the module and computer connected through our E15-USB-T2? If not, determine if USB to TTL conversion is good. The detection method is very simple. Short circuit the serial port RXTX, and the serial assistant will send data to see if the same data can be received; If the adapter board is ready, please confirm the RX TX. |
| ★Question:Use mode 0, connect two USB adapters to the computer, and both parties can send and receive data; Connect one of them to my motherboard and send the protocol code, but there is no response. Communication is normal using the 485 port on my motherboard. |
|
Answer:Check if the wireless module sends data, one connected to the device and the other connected to the computer device. Can the computer receive the data. |
|
★Question:Module testing, one end is connected to a computer and the other end is connected to a microcontroller. The microcontroller can receive data from the computer end, but the microcontroller cannot receive data from the computer end. What is the reason for this? Both ends are |
|
Answer:What microcontroller is used in TX Try connecting a resistor of around 500 ohms in series on the RX. |
|
★Question:Test a pair of modules, with one end connected to the computer and the other end connected to the STM32F103ZET6 microcontroller. The module connected to the microcontroller can receive data when sending data to the module connected to the computer, but the module connected to the computer cannot receive data when sending data to the module connected to the microcontroller. What is the reason for this? It is using transparent transmission mode. |
|
Answer:1. Ensure correct operation and module parameter settings; 2. Ensure that our module can function properly; 3. Add 4-10K pull-up resistors to the TXD and AUX pins of the module, and then test. |
|
★Question:Connect the microcontroller for testing. M0 and M1 are connected to high levels. After the module is powered on and initialized, AUX keeps outputting low levels and cannot read parameters. What is the reason for this? |
|
Answer:1. Ensure that our module is problem free and conduct a separate test to see if the module is functioning properly; 2. What microcontroller to use? Some 5V microcontrollers may require 4-10K pull-up resistors to be added to the TXD and AUX pins of the module. |
|
★Question:What is the networking solution for wireless serial ports? |
|
Answer:Recommend using polling networking. |
