zigbee repeater

I. PrefaceAfter the last study, I believe that we have initially learned to use the ZigBee protocol to send and receive data. Today, we're going to experiment with keystrokes and learn how to implement key interrupts in the protocol stack.Two. Experimental functionOn the protocol stack to implement the key interrupt, BUT1 Press, LED1 flashing two times.Three. Code explanationWe also remember that the previous done the button experiment is how to confi

Research on Controllable networking methods based on ZigBee Wireless Networks (1) ZigBee wireless network application nodes mostly use self-networking to access the network, which may cause excessive consumption of some nodes in the network. In this case, a controllable networking mode is proposed. By selecting and controlling the parent node of a node to access the network, the topology and Node Distribut

Bluetooth was initially standardized to 802.15.1, and later Bluetooth came out with several versions, not standardized to 802 series ZigBee with 6lowpan is a technology developed in the 802.15.4 Layer ZigBee transmission is also 100 meters, it is difficult to do 1-kilometer Sigfox This network should be used by the 802.15.4 of the MAC layer technology + plus others mature physical layer technology, but SI

Notes for flex repeater controls Repeater, as its name implies, means repeat, and repeater is a control used for repetition. The repeater generates the number of child items based on the number of objects in the data source. All the child items generated are in the form of arrays. There is a common problem: No. W

to get every character received. When this character is not '@', it indicates that the input is not complete. Add the character to the character array recv_buf. When this character is exactly, this indicates that the input is complete. Therefore, every character in recv_buf is sent to the PC in order and recv_count is reset.(5) Experiment Results First, complete the hardware connection and open the serial port debugging tool. The configuration parameters are as follows: Click "open serial port

Small projects are really tiring. It seems very simple in principle. The underlying equipment transmits data through Zigbee, and the upper layer equipment uses DTU for data communication. However, there is a problem: DTU is a single transmission. When the upper-layer device performs command control, if the underlying device uploads data, the control command will fail, you must strictly control the data upload time and command processing time. The un

as an Internet of things professional students, feel not to learn these things connected to the knowledge of the Internet can not afford their own, well, learning to start!!! The CC2530 has 21 digital input/output pins, namely p01-p07, P10-P17, P20-P24. In particular, it is important to note that the input and output of the CC2530 pin is different from the 51 single chip microcomputer, look at the comparison of the picture.Well, this has a basic understanding of our own

Keygen first to choose:Why?Before said CC2530 is to support ZigBee protocol wireless chip, in fact, it is this hardware has a support ZigBee protocol Radio Road, not only the circuit, but also a CPU circuit, it is 8051cpu. Then all these circuits are packaged together, called cc2530 chips.Then select GetID, copy the license number below, and copy the key from the back to the corresponding place.Create a pro

ZigBee wireless temperature and humidity collection 1. Experiment Introduction I have been learning ZigBee for almost a year. I have been learning the protocol stack for some time. This semester, because of the computer network course, therefore, I had a deeper understanding of the architecture of the ZigBee protocol stack, a deeper understanding of the operating

ZigBee technology is a wireless communication technology applied to various electronic devices at low transmission rates within a short distance. ZigBee technology has the following features: low power consumption, low cost, low rate, close range, short latency, high capacity, high security, and license-free frequency band. There are three types of devices in a ZigBee
