OTA Upgrade for Bluetooth Device

Bluetooth devices need to be connected to Developer Center on the application. The data interaction between Bluetooth devices and Developer Center during the upgrade process is completed on the application. You can query the upgrade plan for the device on the application. Developer Center sends the upgrade plan to the application. Download the firmware package on the application and share the firmware package to the device. Then an OTA upgrade is completed.

This section introduces the OTA upgrade process for Bluetooth devices.
