Development process

Technical Solutions

Conceptual interpretation
  • gagent: full name Gizwits Agent, running in the Wi-Fi module, the device through Gagent access to the Smart cloud server. Currently compatible with the domestic mainstream Wi-Fi module, developers can also obtain gagent two times development package to achieve custom module access to the smart cloud.
  • Small loop: between smart devices and mobile phones, smart devices and smart devices, by connecting to the same router to communicate within the LAN (view status or control), we call it a small loop.
  • cycle: smart devices through routers or direct access to the Internet to achieve remote monitoring and control of users, we call the big cycle.
  • ProductKey: Product Identification Code, a 32-bit string that is automatically generated after a developer creates a new product through the smart cloud background. In the Smart Cloud database is a unique number, developers to complete the development of writing device Master MCU, the smart cloud through this identification code to identify the device and automatically complete the registration.
  • Did : device number, when a device is first connected to the wit cloud, the wit cloud automatically registers an did for this device according to the ProductKey and the device Wi-Fi module MAC address, which is unique to the user and is used for binding and subsequent operations.
  • passcode: A device pass that verifies the user's binding/control permissions. When the user initiates the device binding, as long as it is legal action to get this pass, through this pass to bind the device and the device for the validity period of the view, control and so on. Gagent generates a random number for the first run as a device pass, which is generated and stored on nonvolatile memory. The device needs to be escalated to the server when it is online.
  • AppID: app ID, when developers need to develop an app for a smart product (including iOS, Android, Web apps, etc.), a AppID is automatically generated and associated with the device in the background. This appid is required for application development.
  • onboarding: also called configuring the network, the user connects a Wi-Fi-based IoT device configuration to the router's process called onboarding. The new device needs to know the router's account number and password for the first time to connect to the Internet via the router. Since most IoT devices do not have their own screens and keyboards, the router's SSID and password need to be sent to the device via a smart phone, a process known as onboarding. The smart cloud provides the ability to access the Wi-Fi device in the SDK already built into this configuration.
  • Airlink: wit Cloud to a variety of smartconfig, SmartLink this UDP broadcast way to the device configuration network technology collectively, compatible with a number of Wi-Fi module vendors Configuration Protocol, Summed up a set of good user experience of the standard onboarding operation process, smart cloud Wi-Fi device Access SDK has built-in Airlink technology.
  • SoftAP: because the Smart Config protocol of each Wi-Fi module vendor is not fully mature, and the 5G router signal is not supported. Wit Cloud provides Airlink configuration mode while also supporting SOFTAP mode to configure device access routers. When the device enters the Softap configuration mode, the device itself will become an AP, the smartphone can be directly connected with the device, and then on the phone interface to enter the router's SSID and password, when the device receives the information will automatically attempt to connect to the router, the connection is successful automatically switch to normal mode of use.

Key Concepts-Digital locations
    • Smart cloud and apps analyze and process the data that the device reports, or the device sends data to the smart cloud and app for analysis and processing, provided the two sides clear the meaning of the data. Wit Cloud Backend provides a definition of data points, data point definition, device and cloud, app-side data communication meaning will be clear.
    • Benefits of Data point definition:
      • Define the meaning of data communication between the device and the cloud and app.
      • Based on data point definition, the cloud resolves device data, and users can use functions such as "Device running status" and "statistical analysis".
      • Wit cloud has big data statistics interface, through the interface, can quickly analyze the device data.
      • It is easy for app developers to develop and the app SDK can parse device data such as issuing/reporting.
      • Easy MCU development, wit cloud according to data point definition, generate MCU and Gagent communication protocol of serial communication.
