ZigBee learning in simple terms Lecture 1

1、 What is? zigbee？ What can it do ？ Why introduce zigbee？
zigbee It is a way of communication between wireless devices , It's similar to people communicating in Mandarin , Mandarin is a way of communication .zigbee Communication mode and zigbee The agreement says the same thing .
node 、 Wireless module 、 Wireless devices are talking about one thing .zigbee The role of building wireless LAN

2.zigbee And wireless sensor networks ？
If a wireless LAN is used for sensor data collection and monitoring , Then this network is called wireless sensor network . Wireless sensor network is a specific application of wireless LAN .
bluetooth ： Low power consumption , The number of network nodes is small 7-8
WIFI: The communication rate is relatively high , High power consumption
zigbee： Advantages can build large-scale network , Power waste . Low defect ： The communication rate is relatively low ,250kbps 
Choose the most suitable according to your own design requirements , There is no good or bad distinction .
Mobile phones can't communicate directly with zigbee The module directly carries out wireless communication , See the mobile control zigbee Modules are transferred through the program on the computer , The computer is equivalent to a serial port WiFi Tools for .

4. Learning methods ：1. Get involved in watching the video , Create electronic notes , Follow the experiment 、 Grab the bag 、 Simulation .2. video 1-6 Look in order , Learn first 7 The use of the protocol stack in the previous section of the section and the 8 part zigbee Related concepts and principles of wireless communication , Unicast experiment , After knowing and mastering these two parts , Research on OSAL And compare and learn other communication methods behind . about 8-12 Partial content , Let's go through it first , Download the example program to see how to build a perceptual understanding of the direct machine , Let's take a closer look at learning .
