The Wi-Fi Alliance named "Halow" for Low-Power Wi-Fi" A few days ago, the Wi-Fi Alliance announced the certification program at the Consumer Electronics exhibition in Las Vegas, USA. When enterprises purchase a Wi-Fi Halow product, they can ensure that the product uses 802.11ah technology developed by the Institute of Electrical and Electronics Engineers (IEEE. Lisa Phifer, technical consultant at Core Compentence, said: "This is very important because it provides global standards for intero

ZigBee is mainly used for remote control of home appliances, which is a short-distance, low-power wireless communication technology.18. The main functions of PPP include two protocols: (1) does

(the key technologies for the IoT TCP/IP layer will be addressed in a separate article, so stay tuned). The message push technology mentioned in this paper is the application layer protocol technology based on TCP/IP protocol.Let's go further by abstracting the Internet of things that are based on IP architectures, such as (ignoring basic technologies such as web and routing):Visible, the core component is the IoT device things, Gateway and cloud. IoT equipment is divided into two categories, o

The common transmission modes in the IoT World include: Mobile network (2G/3G/4G), WiFi, Bluetooth, ZigBee and other traditional transmission methods, and based on NB-IoT, Lora and other emerging transmission methods.

1, just beginning, we really need to use the official template, add simple code, make communication Basic transceiver experiment, establish perceptual understanding.2. Then, on the basis of the basic experiments of the official code, to understand the relevant concepts, master the principle of communication process, combined with their own understanding, do a personalized experiment, to verify our understanding3. Unicast, broadcast, multicast, binding1) unicast refers to: in the

. The second application scenario, in essence, is the internet of things, but it is an internet of things gateway to illustrate it alone. The so-called IoT Gateway, basically a communications conversion device, can be the local wireless communications, such as Bluetooth, ZIGBEE,Z-WAVE,NFC, and so on, into the IP protocol, and sent to the internet of things backstage. At the same time, the IoT network Sekiya the logical processing of local events based

Master the basic working circuit of ZigBee Wireless module.2, the above chip with the emulator connection needs 5 wires, power, ground, reset, P2_1, p2_2.Output configuration: A, the first to make the corresponding IO port in the normal IO port mode, non-on-chip peripheral mode, B, so that the normal IO port in the output state, non-input state, C, directly to the corresponding IO port assignment, the corresponding value is output.The input or outp

To do embedded development, UART is almost essential, debugging serial port, GPS, GPRS, Bluetooth and many other modules are used UART interface. Nowadays the hot IoT also has the UART figure, the serial port ble, WIFI, Zigbee, Lora and so on module, a bunch of piles. The NUC972 mentioned in the previous article even built up 11 UART, it can be understood. Although has been based on the serial port to do a lot of tool software, such as s3c2410 of the

A long time did not write the log, previously felt very waste of time, always do not want to write. QQ Space also did not go to publish something, even said the state has not changed. In the Baidu space to open a personal homepage, at that time learning ZigBee just for their own view of the post is convenient, do not know whether people become lazy or really have no time. But later there is time or a lot of updates, is a momentary whim. Try to have a

operation depends on the last operation being completely successful.Gateway Publishing ProcessThe server publishing process is similar to the client, which needs to detect if its subject has been pre-registered with the client before publishing, and if it is not necessary to send the subject and the specified topic ID into the register message to the client for the registration process, then wait for the client to process the result regack. The registration is passed before the publish message

With the rapid growth of data and multimedia services, the demand for positioning and navigation is growing, especially in complex indoor environments, in environments such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, and mines, it is often necessary to determine the location of mobile terminals or their owners, facilities and items in the room.GPSIt is currently the most widely used positioning technology.

EPC (Electric Product Code) is a standard for the sensing layer of the Internet of things, mainly to define how to define the electronic tag, which includes many rules.The Internet of things is divided into three layers: the perceptual layer, the network layer and the application layer. Perceptual layer is the direct contact layer of objects and objects, like the battlefield of war, such as our bus, IC card and receiver is in the perceptual layer, is the matter and things between each other perc

Some of the code is as follows://pan IDuint16

At present, the operating system provides services, mainly concentrated in the "connection" aspect, "difference" aspect, IPV6 although a bit inconvenient, but always have Bentou, "identify" aspect, also temporarily no good idea, with remote interface can solve "things and people" communication between the problem.con

-Fi), is being commercialized by a derivative company Jeeva Wireless. Passive Wi-Fi uses a back-scattering Wi-Fi signal to connect a battery-free device to a traditional device, such as a computer or smartphone. In the test, the passive Wi-Fi prototype transmits data to 100 feet, enabling a wall-through connection. Doing so requires changing the Wi-Fi access point software to produce an additional signal for use by passive Wi-Fi devices, which can slightly increase power consumption.The power co

development trend is in line with our "Green, innovative" research purposes. In fact, at present, the four-around aircraft we have studied has a fatal defect-that is, in the case of an unexpected power failure, the battery will inevitably completely follow the bad aircraft. As a result, our group is still ready to use solar cells as the secondary output mode. Solar Power provides power to maintain the hovering of the fuselage, that is, the plane can land slowly from high altitude without the ne

. Strip down the example Android app to the communication part and implement your own use cases. To make it a bit easier I provided my example Android app and my stripped down version of the demokit. pdatGitHub. feel free to play around with it. note that my approach wocould be considered as a temporary hack or proof concept rather than a good solution of the porting problem. so when new versions of the adk will be released you wowould have to modify them again which wowould be painful.
