s11, issuing a Mesh node firmware version file;
step S12, checking whether the version file is correct after downloading, returning the result to the cloud, and if not, continuing to step S13 if correct;
step S13, issuing the downloaded firmware version files of the Mesh nodes through BLE connection;

Through the embodiment, the mobile phone is connected with one Mesh node, and then all Mesh nodes in the network can be upgraded; the nodes in the network determine the structure in the network by self-layering according to whether the nodes can receive messages of other nodes in the network or not without manual work or program participation; duplicate removal and message continuity judgment can be carried out according to the message source address and the message SN, and the situation that version file data are disordered in the communication process is not needed to be worried about.
Furthermore, the Mesh node determines the network structure through a message mechanism, so that the sending direction of the version file data and the feedback direction of the upgrading result in OTA are determined without manual work or program participation. The Mesh node performs message duplicate removal and message continuity judgment through the message source address and the message SN, and does not need to worry about upgrading failure caused by version file data confusion.

and under the condition that a fourth wireless mesh network node connected with the third wireless mesh network node exists, the upgrade version file is sent to the fourth wireless mesh network node through the third wireless mesh network node.
4. The method of claim 2, wherein transparently transmitting the upgraded version of the file to the first wireless mesh network node via the proxy node comprises:
instructing the agent node to perform a verification operation on the upgraded version file;
and under the condition that the upgrade version file passes the verification operation, the upgrade version file which completes the verification operation is transmitted to the first wireless mesh network node through the proxy node.
5. The method of claim 2, wherein prior to transmitting said upgraded version file to a second wireless mesh network node by said first wireless mesh network node, determining whether said first wireless mesh network node and said second wireless mesh network node are single-connected by:
determining that the first wireless mesh network node and the second wireless mesh network node are connected in a single connection if no wireless mesh network access exists between the second wireless mesh network node and the proxy node and a unique wireless mesh network access exists between the first wireless mesh network node and the second wireless mesh network node.
6. A node upgrade apparatus, comprising:
the wireless mesh network updating system comprises an acquisition module, a storage module and a updating module, wherein the acquisition module is used for acquiring version file information of all nodes of the wireless mesh network stored in a proxy node in the wireless mesh network and an updating version file received by the proxy node from equipment, and the proxy node is any wireless mesh network node which establishes BLE connection with the equipment in the wireless mesh network;
the processing module is used for sequentially transmitting the upgraded version file to all nodes of the wireless mesh network through the proxy node in a fission mode under the condition that the version file information has a version lower than that of the upgraded version file so as to enable all the nodes to carry out node upgrading according to the upgraded version file;
a verification module for sending firmware version information to the device through the proxy node to instruct the device to download the upgrade version file from a remote server if the firmware version information is inconsistent with firmware version information of a firmware version file stored in the remote server; receiving, by the proxy node, the upgraded version file from the device.
7. The apparatus of claim 6, wherein the processing module further comprises:
the first processing unit is used for transparently transmitting the upgrade version file to a first wireless mesh network node through the proxy node, wherein a wireless mesh network access exists between the first wireless mesh network node and the proxy node;
and the second processing unit is used for sending the upgrade version file to a second wireless mesh network node through the first wireless mesh network node under the condition that the first wireless mesh network node has the second wireless mesh network node connected with the first wireless mesh network node.
8. A computer-readable storage medium, comprising a stored program, wherein the program is operable to perform the method of any one of claims 1 to 5.
9. An electronic device comprising a memory and a processor, characterized in that the memory has stored therein a computer program, the processor being arranged to execute the method of any of claims 1 to 5 by means of the computer program.
