In the IoT platform design process, my middleware needs to process the package from the hardware side, on the other hand, it needs to process the package from the client side, including the Web side and the mobile terminal, etc. So it is very necessary to write a unified CRC authentication.So, at the beginning of the design, what exactly is CRC certification? The so-called CRC authentication, refers to the hardware side or the user before data transmi

Iot security: multiple security vulnerabilities in LED lights Recently, a foreign security expert found that Zengge's Wi-Fi LED lamp has multiple security vulnerabilities. ZENGGE is a high-tech company integrating LED Controller Product R D, manufacturing, sales and engineering design, installation and service. Wi-Fi LED lights are LED Bulbs connected by Wireless WIFI. Such lights can be used as routers, HTTP servers, HTTP proxy servers, and many ot

(I) origins of hot and Iot The storage speed of heap organization tables is faster because sorting is not required. However, to find records that meet certain conditions, you must read all the records for filtering. At this time, the index will appear to speed up the query. The index is used to sort and store the values of a few specific fields and record the position in the table, Because the index is ordered, it is easy to query the specific record

device. The Code is as follows: 1 this.DevicePriority=DevicePriority.Priority; 4.4 host program service instance configuration considerations When creating a service instance in the Host Program, you need to set the configuration parameters of the service instance to polling communication mode, start the service instance, and add the instantiated device driver to the service instance.

After adding JSON support to IoT Coap, it becomes very interesting, at least we can get the results we want. In the previous article we introduced some common tools--coap the command-line toolset.COAP Client code exampleBefore we start we need to have a client-side code so that our server can return the correct data and parsevar coap = require (' Coap '); var requesturi = ' coap://localhost/'; var url = require (' URL '). Parse (RequestUri + ' id/1/')

development based on the IOT middleware platform will avoid such problems. (1). The platform comes with related drivers (you can also develop it on your own and reuse it later ). (2) remote configuration, remote deployment, and driver replacement at any time. (3) The driver is completely decoupled from the business logic. The following uses RFID card swiping as an example to describe how to develop related programs based on yfios
