Environment: Raspbian-stretch (2018-06-27)Raspberry Pi: 3 generation B Type1, Raspberry Pi equipment, need to be in the field can also have independent networking capabilities, it is necessary to use the Internet of Things module.The SIM868 communication module for micro-snow is used here, such as:2, will SIM868 inserted in the empty display board, SIM868 used is unicom 4Gsim card, in fact SIM868 using Pin#

At the end of 2017, for the development of the Internet of things in the 2018, the major research institutes have published a large number of research reports, although the content is different, but for the development of the Internet of things in 2018 is very optimistic. In the eyes of various research institutions, t

For many IoT applications, using a Raspberry Pi to build an intelligent gateway is no longer appropriate, but the market of those "XX smart", "XX center" direct seconds kill it!Hardware needs to be extended: SD card, WiFi, Bluetooth, USB hub,tft display.What software is needed: scripting engine, remote login service, Web server, messaging server, processing server, forwarding server, Smart Display software, interactive control software ... Some of these software are already mature, some are stil

C114 News September 2 (sub-month) in the history of the development of communication industry, it has been accompanied by the competition and integration of technical standards, such as TDD and FDD, NGN and Ngi,bluetooth and ZigBee. In recent years, the development of the Internet of

Using the Weibo APIOn-line search, Weibo opened the micro-blog private messages API, but also see some API usersSpit the micro Bo randomly close the API, so this TBD3. Using the Fetion APIBecause the official does not publish the API, the use of private APIs will create instability,And it doesn't necessarily support the s

management is quite flexible. For example, enterprise customers can manage the card's activation and deactivation, such as the granularity of traffic monitoring to 500KB and 10Min two dimensions, close to real-time monitoring, or for example, can realize the card package changes in real-time effective, different from the traditional to take effect the limit, so that each billing cycle before the end, Can be adjusted according to the actual traffic usage to the best plan, or according to the rea

Understanding of Software Engineering:Software engineering is in accordance with the management of engineering, organized, planned, in a certain quality basis, time limit and cost range, the realization of a clear-functional system. Like a construction project, the need for pre-measurement, calculation costs, expected time, division of labor, medium-term follow-up progress, quality assurance, late detection, maintenance, in each period of time to do a good job, can be called a complete perfect p

The most common architecture partitioning method for the Internet of Things is to divide the overall architecture into 3 levels, the perceptual layer, the network layer and the application layer. The perceptual layer is at the bottom: it has two functions: collecting the environmental information through the sensor, and interacting with the environment with the operation actuator on the other. The prima

and Android a decade ago, and 10 years later, Microsoft is clearly reluctant to let history repeat itself in the internet of things. This is where Windows IoT was born. What is Windows IoT Windows IoT is interesting, and its current version is a streamlined kernel based on WINDOWS10, which is optimized for tiny devices. Windows IoT also supports the UWP (Universal Windows Platform) programming interface fo
