Multi-device batch firmware upgrading method for mesh network device

Abstract

The invention provides a multi-equipment batch firmware upgrading method for a mesh network device, which comprises the following steps that: a host generates a firmware compression packet with an identifier and sends the firmware compression packet to root node device of a mesh network; the root node device decompresses the firmware package, verifies the correctness of firmware, repackages and compresses the firmware, and pushes the firmware to the target node device in a multicast mode; the upgrade firmware supports breakpoint resume in the transmission process of the mesh network; and the target node device decompresses the firmware, performs CRC on the firmware identifier, and upgrades and restarts the firmware after passing the CRC. If the target node device is restarted abnormally, returning to the old version for starting. The target node device reports the version to the host after being started, and the host confirms whether upgrading succeeds or not. Through compression and breakpoint resuming, consumption of network and storage resources in the firmware transmission process is reduced, and the batch upgrading speed is increased; through firmware type inspection and a version fallback mechanism, device upgrading exception caused by mismatching of firmware and the to-be-upgraded device is prevented.

Description

technical field [0001] The invention relates to the technical field of wireless mesh networks, in particular to a method for upgrading firmware of mesh network devices in batches for multiple devices. Background technique [0002] In the current technology, mesh network devices usually use a single device to be upgraded one by one, and the firmware needs to be transmitted from the host to the device to be upgraded at one time. In this upgrade method, once a packet of data is lost during transmission, all data needs to be retransmitted, resulting in slow upgrade speed and low upgrade success rate. Moreover, this upgrade method does not have a complete firmware inspection mechanism. There are usually many different types of devices in the mesh network, so it is easy to cause a mismatch between the upgraded firmware and the device, affecting the normal operation of the device.

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a batch firmware upgrade method for multiple devices of mesh network devices, which mainly solves the problems in the above-mentioned prior art: the size of firmware transmission data is reduced, and packet loss occurs when firmware is transmitted in a wireless network. No need to re-transfer at any time, solve the problem that the new firmware and the device do not match, causing the upgrade to fail and make the device work incorrectly
