In this tutorial, learn to perform simple Client to Client Communication over Zigbee Protocol. There will be two Xbee modules taken and will be configured to communicate data with each other over the air. The Xbee devices communicate with each other wirelessly over the air. They do not have any microcontroller or processor in themselves, so they cannot manage the received or sent data.
Zigbee Protocol and Standard : IoT Part 35
In the previous tutorial, the basics of Wireless Sensor Networks were discussed. It was mentioned that WSN can utilize many wireless standards and protocols to enable sensor communication with a cloud or server. It was also mentioned that wireless sensors communicate to a cloud or server with the help of a Gateway which performs protocol conversion for the wireless network. Zigbee is one of the standard and protocol which is generally used for WSN deployed in industrial applications.
Wireless Sensor Networks (WSN) : IoT Part 34
The sensors and actuators have an important role in IoT. It the sensors and actuators that enable IoT devices to interact with the physical world. The large IoT applications like smart home, smart transportation, smart grid and many others are intelligent systems that connect the world in an automated way to ease human efforts. The collective aim of such systems is to nurture the concept of IoT which is fulfilled with the use of tiny sensors. The whole Sensor Network is tightly coupled directly or indirectly with communication Network (Internet) where intelligent monitoring, management, and data processing can be achieved via the usage of networked cloud computing devices.
Client Server Communication over CoAP Protocol : IOT Part 33
In the previous tutorial, advantages of CoAP protocol over TCP/IP and UDP protocols in IoT applications were discussed. The CoAP protocol is specially designed for constraint devices and networks. In this project, the application of CoAP protocol in IoT will be demonstrated. In this project, an ESP8266 Wi-Fi modem will be configured as CoAP server and a laptop will be used as CoAP Client. Both Client and server will be co-located communicating through same Wi-Fi router so, the ESP board will act as a local server. The CoAP Client could send data to the server on a particular port with the help of browser add-on – Copper (Cu) CoAP user-agent. In fact, the Copper (Cu) itself will act as CoAP Client.
Constrained Application Protocol : IOT Part 32
The IoT devices have very limited resources like they have embedded processors or controllers, limited RAM and ROM and they need to operate on battery without replacement for weeks, months or even years. Even they have to communicate data swiftly though small in amount but on limited network bandwidth.
