Thus, the validity of the upgrade content can be ensured.
Optionally, after determining the upgrade package fragment offset, the method further includes: caching the fragment offset of the upgrade package; and under the condition of recovering the network connection after the network disconnection occurs, acquiring the upgrade package fragment content according to the cached upgrade package fragment offset. Optionally, the upgrade package fragment is offset to upgrade package fragment location information.
Caching the fragment position information of each upgrade packet; and after the network connection is disconnected and the upgrading is interrupted, under the condition of replying the connection with the cloud platform, continuing to download from the downloading progress during the interruption of the upgrading according to the cached upgrading packet fragment position information without completely downloading again. The upgrading time can be saved, and the remote upgrading efficiency of the internet of things equipment is improved.
Optionally, in a case that the upgrade instruction is received, the method further includes: obtaining upgrading information corresponding to the upgrading instruction; the upgrading information comprises an upgrading identifier, the total length of an upgrading packet and a serial number of the internet of things equipment; and storing the upgrading information.
In some embodiments, in the case of receiving an upgrade instruction, an upgrade flow is started and upgrade information is retained in the flash memory flash. In the process of downloading the fragment content of the upgrade package, when the power failure causes the upgrade to be interrupted, when the power supply is recovered and the cloud platform is accessed again, the upgrade is automatically initiated according to the upgrade information stored in the flash and the fragment content of the upgrade package is downloaded from the beginning, so that the remote upgrade of the internet of things equipment is not influenced even if the power failure occurs.
Optionally, after the upgrade is performed according to the upgrade package fragment content, the method further includes: and reporting the upgrade completion information to the cloud platform.
According to the method for upgrading the internet of things equipment, the upgrading information is stored in the flash memory, so that the internet of things equipment can still automatically initiate upgrading after being restarted by unexpected power failure, the influence of power failure is avoided, and the reliability of upgrading the internet of things equipment is improved. By the aid of the cached fragment position information of the upgrade package, after the network is disconnected and reconnected, the download can still be started from the download progress when the upgrade is interrupted without complete re-download, and remote upgrade efficiency of the internet of things equipment is improved. In the process of downloading the fragment content of the upgrade package, the request information of the fragment content of the upgrade package is retransmitted over time, the fragment content of the upgrade package is verified, and the whole package is verified, so that the integrity and the legality of the firmware are ensured, and the upgrade and brick change of the equipment of the internet of things are avoided.
