Internet of things OTA Upgrade solutions

Advantages of cloud platform
  • Mainstream ChipPlatform Adaptability

  • Core differential technology

  • Improve the complementary toolchain

  • Global service support capability

  • Safe, stable and reliable

  • Single chip solution
  • Scenario

    This scenario is for single chip devices of the Internet of things to upgrade directly online or indirectly access to the public network through the gateway Wi Fi / BT / USB / ZigBee.

  • Client

    UC SDK is integrated in the application layer, which is mainly responsible for the control of the upgrade process, providing networking, reporting, downloading, verification, storage and other interfaces to the user app call;

    UA SDK is integrated in the boot layer, which is mainly responsible for restoring differential packets locally and writing them through bootloader

    For Linux / Android / RTOS / QNX operating system, UA SDK needs independent recovery partition

  • Typical case

    Direct networking - bike sharing, smart watch, car machine, GPS tracker, dash cam;

    Indirect networking - Smart bracelet, beacon device, ZigBee smart home, rearview mirror;

  • Multi chip system upgrade solution
  • Scene description

    This scenario is oriented to upgrade the device system composed of multiple MCU

    The main chip of the device is connected with other MCU through internal bus such as uart/spi/can

    Mixed upgrade solution of multi system in device (Linux / Android / RTOS / QNX operating system)

  • client

    UC SDK is integrated in the application layer, which is mainly responsible for the control of the upgrade process, providing networking, reporting, downloading, verification, storage and other interfaces to the user app call;

    UA SDK is integrated in the boot layer, which is mainly responsible for restoring differential packets locally and writing them through bootloader

    For linux/android/rtos/qnx operating system, UA SDK needs independent recovery partition

  • classic case

    Upgrade of independent MCU in vehicle engine system; The robot system is connected to the Internet through the communication module, and the main CPU is connected to the independent MCU and the upgrade of different operating systems.

  • Brief introduction

    This scenario is for single chip devices of the Internet of things to upgrade directly online or indirectly access to the public network through Wi Fi / BT / USB / ZigBee.
