Before the OpenFOTA solution, the module only supported upgrading the module's firmware and application APP, after using Open FOTA, the module can upgrade the MCU's firmware and application APP, which can be called Firmware Upgrade (FOTA) and Application Upgrade (SOTA) respectively from the perspective of the whole device terminal.

Therefore, the Open FOTA solution is equivalent to empowering the FOTA upgrade capability and SOTA upgrade capability of IoT devices at the same time.
