step two, caching the firmware upgrade package of the low-power-consumption bluetooth mesh device 207 to the second bluetooth mesh device 203, as shown in fig. 15;
step three, after the low power consumption bluetooth mesh device 207 is awakened regularly, a task is acquired from the second bluetooth mesh device 203, after the second bluetooth mesh device 203 acquires the OTA upgrade task, the OTA upgrade service is started, and then the second bluetooth mesh device 203 initiates OTA upgrade to the low power consumption bluetooth mesh device 207, as shown in fig. 16.

alternative path two, mesh gateway 200 → fourth bluetooth mesh device 205(-35dbm) → fifth bluetooth mesh device 206(-13 dbm);
the link number of the alternative path I and the link number of the alternative path II are both 2, the sum of the signal quality of the alternative path I is-35 dbm, and the sum of the signal quality of the alternative path II is-48 dbm; since-35 dbm > -48dbm, alternative path one is chosen, as shown in fig. 6, according to the principle that the signal strength is the greatest with the same path length.
In another embodiment of the application, the determining subunit includes a third determining module, where the third determining module is configured to determine, when there are two alternative paths, a first alternative path is shorter than a second alternative path, the busy node exists in the first alternative path, and the busy node does not exist in the second alternative path, the second alternative path as the firmware upgrade path. When the busy node exists in the alternative path, the time for transmitting the firmware upgrade package is increased, so that the alternative path without the busy node is preferentially selected, and the firmware upgrade efficiency is further improved.
As shown in fig. 7, the hatching indicates that the bluetooth mesh device is busy, and the first bluetooth mesh device 202 and the fifth bluetooth mesh device 206 are busy.
Example 1: selecting a link path for performing OTA upgrade on the second bluetooth mesh device 203:
alternative path one, the mesh gateway 200 → the first bluetooth mesh device 202 → the second bluetooth mesh device 203;
alternative path two, mesh gateway 200 → fourth bluetooth mesh device 205 → third bluetooth mesh device 204 → second bluetooth mesh device 203;
the number of the alternative path I links is 2, and the number of the alternative path II links is 3;
according to the shortest link principle, a first alternative path should be selected, but the first bluetooth mesh device 202 on the first alternative path is in a busy state at this time and is not selectable, so that only a second alternative path can be selected, as shown in fig. 8;
in another embodiment of the application, the cloud device further includes a first sending unit and a first setting unit, where the first sending unit is configured to send a firmware upgrade package to the target bluetooth mesh device based on the firmware upgrade path control, so as to send the firmware upgrade package and the firmware upgrade path to all nodes on the firmware upgrade path in a firmware upgrade process, where the nodes include the mesh gateway, the target bluetooth mesh device, and/or the non-target bluetooth mesh device; the first setting unit is configured to set all the nodes to a busy state after the firmware upgrade package and the firmware upgrade path are sent to all the nodes on the firmware upgrade path and before the firmware upgrade is performed. In this embodiment, all nodes on the firmware upgrade path are set to be in a busy state, so that when firmware upgrade is performed on other target bluetooth mesh devices, other nodes can be selected as the firmware upgrade path, thereby avoiding transmission time increase caused by passing through the nodes, and further improving the OTA firmware upgrade efficiency of the bluetooth mesh devices.
As shown in fig. 9, the hatching indicates that the bluetooth mesh device is in a busy state, and if the alternative path two (the mesh gateway 200 → the fourth bluetooth mesh device 205 → the third bluetooth mesh device 204 → the second bluetooth mesh device 203) is selected as the firmware upgrade path, the bluetooth mesh device in the alternative path is set to be in the busy state.
In another embodiment of the present application, the cloud device further includes a second setting unit, where the second setting unit is configured to set, after all the nodes are set to a busy state, the current node to an idle state after the current node successfully sends the firmware upgrade package to a next node. After the current node successfully sends the firmware upgrade package to the next node, the current node is indicated to have been successfully transmitted, and no relevant transaction is processed at this time, so the current node is set to an idle state to prompt that the current node of the system can be used as a node in a firmware upgrade path.
As shown in fig. 10, the mesh gateway 200 initiates OTA firmware upgrade packet caching for the fourth bluetooth mesh device 205; as shown in fig. 11, the fourth bluetooth mesh device 205 initiates OTA firmware upgrade packet caching for the third bluetooth mesh device 204; as shown in fig. 12, the third bluetooth mesh device 204 initiates OTA firmware upgrade packet caching for the second bluetooth mesh device 203; as shown in fig. 13, the OTA firmware upgrade packet of the second bluetooth mesh device 203 is successfully received.
In order to further improve the efficiency of upgrading the OTA firmware of the bluetooth mesh device, in another embodiment of the present application, the cloud device further includes a generating unit and a second sending unit, where the generating unit is configured to generate a prompt message after setting the current node to an idle state, and the prompt message is used to prompt that the current node is in the idle state; the second sending unit is used for sending the prompt information to the mesh gateway. In this embodiment, after the current node is in the idle state, prompt information is generated in time and sent to the mesh gateway, so that the node can be selected as an upgrade path in time when a firmware upgrade path is determined.
In a specific embodiment of the present application, the firmware upgrading method may also be applied to OTA firmware upgrading of a bluetooth low energy mesh device, as shown in fig. 14, where the mesh gateway 200 needs to perform OTA upgrading on the bluetooth low energy mesh device 207. In a traditional mesh upgrading mode, 200 minutes are needed for upgrading under a normal network condition by using a 200K firmware, equipment is required to be in a normal working mode for several hours, and the influence on the service life of the battery equipment is fatal. The steps of upgrading by adopting the firmware upgrading method are as follows:
step one, a friendship relationship is established between a second Bluetooth mesh device 203 and a low-power Bluetooth mesh device 207; (the mesh protocol stack supports the low-power consumption Bluetooth mesh equipment, establishes friendship relationship with Friend nodes, and caches tasks received during the dormancy of the Bluetooth mesh equipment);
step two, caching the firmware upgrade package of the low-power-consumption bluetooth mesh device 207 to the second bluetooth mesh device 203, as shown in fig. 15;
step three, after the low power consumption bluetooth mesh device 207 is awakened regularly, a task is acquired from the second bluetooth mesh device 203, after the second bluetooth mesh device 203 acquires the OTA upgrade task, the OTA upgrade service is started, and then the second bluetooth mesh device 203 initiates OTA upgrade to the low power consumption bluetooth mesh device 207, as shown in fig. 16.
By the method, the OTA upgrading time of the low-power-consumption Bluetooth mesh equipment is shortened from several hours to several minutes, so that the power consumption of firmware upgrading of the low-power-consumption Bluetooth mesh equipment is greatly reduced, and the problem that the firmware of the low-power-consumption Bluetooth mesh equipment is difficult to upgrade is solved.
