Make Your Own IoT Device by ZigBee
0 likes110 views
The document discusses how to make your own Internet of Things (IoT) device using ZigBee technology. It explains the concepts of IEEE 802.15.4 and ZigBee standards and how they interact. It provides details on ZigBee network topologies, device roles, and the process of forming and joining a ZigBee network. It then gives an example of creating a smart home thermostat IoT device using XBee modules and Arduino.

1. Using X-CTU software to set up XBee
• con
fi
gure coordinator and router with same PAN ID
• Set coordinator as API mode, router as AT mode
• Set Channel Veri
fi
cation to 1 [Enabled] for router
• Set D3 in I/O setting as ADC for analog input for router
• Set I/O sampling Rate as 1388 in hex (5000ms) in I/O sampling setting for router
2. Writing Arduino code and upload to coordinator and router. github
3. Following my Wiring layout and put things together

Hey, my PAN ID is 8080, welcome to join. Single hop broadcast Active scan: 1. scanning node sends request to local ZR/ZC 2. responding nodes send indication about network

- 25. Series What?
- 26. Series 1 X B e e S 1 I’m also called XBee 802.15.4. I’m easy to work with, no need to be con fi gured. I can form a point-to-point communication. Oh…By the way, I don’t speak to Series 2. Never. We’re not going to talk. Nope..STOP thinking about it..!
- 27. Series 2 X B e e S 2 I must be con fi gured before using me. I can run in AT/API mode. But it all depends on what fi rmware installed on. Not only p2p I can run but mesh network is also con fi gurable. So basically I’m a ZigBee XBee. Oh…By the way, I don’t speak to Series 1. Never. We’re not going to talk. Nope..I don’t even know him..!
- 28. XBee Operating Modes 28 xbee --mode AT XBee:~$ It’s Application Transparent. * In AT command mode, everything got in Rx of XBee will be sent out via antenna. * The incoming data from antenna will go to Tx xbee --mode API XBee:~$ It’s Application Programming Interface This requires that communication with the module be done through a structured interface; in other words, data is communicated in API frames.
