Firmware Upgrade

Overview

The performance of NB-IoT chipset is constantly updated and optimized, and the chipset firmware of devices needs to be upgraded accordingly. The upgrade of NB-IoT modules is called firmware upgrade.

Prerequisites

Before upgrading the firmware, ensure that the device supports the firmware upgrade.

1. Choose Product > Product Development. Click a product name to enter the product space.

   

2. In Define Profile section to view OM Maintenance details, and ensure that Filmware Upgrade function is enabled.

   

Uploading a Firmware Package

1. Choose Product > Upgrade Debugging > Upgrade Package Management > Firmware, and click Upload Unsigned Firmware Package.

   

2. Upload the firmware package according to the wizard.
   1. Select a product and click Next.
      NOTE:

      The firmware package contains only the bin file used for firmware upgrade. Therefore, the Developer Center cannot directly obtain the product model information from the firmware package. You need to select a product and associate it with the firmware package.

      

   2. Select the unsigned firmware package to be uploaded, enter the version number of the firmware package, and click Submit.

      

Creating a Firmware Upgrade Task

      • Execution Type indicates the time when the Developer Center delivers an upgrade task to the device. The value options include Now, Custom, and Device Online.
      • Retry Parameter indicates whether to execute failed task again.

      

   2. Select a product and click Next.

      

   3. Select the firmware package to be upgraded and click Next.
