Fig. 2 is a flow chart of an over-the-air method for a network of node devices according to an embodiment of the present disclosure. As shown in fig. 2, the process of over-the-air in the network of node devices may include:

step 201: and under the condition that the upgrade notification sent by the gateway equipment is received, the first MCU sends a first upgrade request to the gateway equipment.

In the node device network shown in fig. 1, any node device may be upgraded in a unicast manner, that is, the gateway device may download an upgrade packet, that is, an OTA data packet to be upgraded, to the local and store the upgrade packet, and the gateway device may notify the node device that the upgrade may be performed, that is, the first MCU in the node device may receive the upgrade notification sent by the gateway device. In some embodiments, the first MCU may be a wireless communication module MCU in a home device.

After receiving the upgrade notification, the first MCU may generate a first upgrade request carrying first split information according to the first MCU firmware information, where the first split information includes: one or more of unpacking minimum unit information, unpacking offset address information, and the like.

The near-field radio frequency wireless communication technology (such as bluetooth mesh, zigbee and the like) has the characteristics of short communication distance, low speed, small transmission data volume and the like, so that the node equipment adopting the near-field radio frequency wireless communication technology also has the characteristic of small transmission data volume, and the determining the first split information according to the first MCU firmware information comprises: one or more of unpacking minimum unit information, unpacking offset address information and the like, and further generating a first upgrading request carrying first unpacking information, wherein the first MCU in the node equipment can send the first upgrading request to the gateway equipment through a near-field radio frequency wireless communication technology.

Step 202: and receiving an over-the-air OTA data packet to be upgraded, which is sent by the gateway equipment, and carrying out OTA upgrading.

The first splitting information is carried in the first upgrading request, so that the gateway device can unpack the OTA data packet to be upgraded according to the first splitting information to obtain corresponding first OTA unpacking information, wherein the first OTA unpacking information can comprise: after unpacking, OTA data and corresponding unpacking offset address information. Alternatively, in some embodiments, the first OTA unpacking information may further include: and serial number identification information corresponding to each unpacked OTA data.

The gateway device may sequentially send the first OTA unpacking information, so that the first MCU receives each first OTA unpacking information sent by the gateway device, and then performs whole package verification on all the received first over-the-air OTA unpacking information, and under the condition that verification is determined to be successful, integrates and stores unpacked OTA data in each first OTA unpacking information.

In some embodiments, the gateway device sends the first OTA unpacking information with the sequence number identification information of "n", and may wait for the response information of the first MCU, and after receiving the response information of the first MCU, send the first OTA unpacking information with the sequence number identification information of "n+1" to the first MCU. If the response information of the first MCU is not received, and the sending times of the first OTA unpacking information with the serial number identification information of n is smaller than the set times, the first OTA unpacking information with the serial number identification information of n can be retransmitted. Wherein n is a natural number. Of course, when the response information of the first MCU is not received and the number of times of sending the first OTA unpacking information with the sequence number identification information of "n" is greater than or equal to or less than the set number of times, the failure of the current OTA upgrade, that is, unsuccessful verification, is indicated.

In some embodiments, the gateway device may sequentially send the first OTA unpacking information, and after determining that the first OTA unpacking information is sent, may send a transmission end instruction, and send a sequence and a check code, so that the first MCU may perform whole package check on the received first over-the-air OTA unpacking information according to the received sequence and the check code, and integrate and save the unpacked OTA data in each first unpacking information under the condition that the check is determined to be successful, otherwise, the check is unsuccessful, and the first OTA unpacking information may be discarded, where the OTA upgrade fails.

And integrating and storing the unpacked OTA data in each piece of first unpacking information, namely, the first MCU can carry out OTA upgrading.

Of course, when the first MCU is successfully upgraded, the first MCU version information may also be synchronized to the gateway device. Therefore, the gateway equipment can synchronize with the APP in the user terminal through the OTA platform, so that the user can know the upgrading situation in time.

Step 203: and under the condition that the OTA data packet to be upgraded comprises the second MCU upgrading information, synchronizing the OTA data packet to be upgraded to the second MCU, so that the second MCU performs OTA upgrading.

In an embodiment of the present disclosure, a node device includes: and two or more MCUs, so that the first MCU can inform the second MCU of carrying out OTA upgrading under the condition that the OTA data packet to be upgraded comprises second MCU upgrading information. In some embodiments, the first MCU may send upgrade synchronization information to the second MCU; receiving a second upgrading request carrying second splitting information sent by a second MCU, wherein the second splitting information is generated by the second MCU according to second MCU firmware information; unpacking the OTA data packet to be upgraded according to the second splitting information to obtain second OTA unpacking information; and transmitting each second OTA unpacking information to the second MCU, so that the second MCU performs OTA upgrading and transmits upgrading synchronization information.

The second MCU may determine second split information according to the second MCU firmware information, where the second split information also includes: and generating one or more of corresponding unpacking minimum unit information, unpacking offset address information and the like, and then generating a second upgrading request carrying second unpacking information, so that the first MCU can unpack the OTA data packet to be upgraded according to the second unpacking information to obtain each piece of second OTA unpacking information. Likewise, the second OTA unpacking information includes: and then, each second OTA unpacking information can be sequentially sent to the second MCU, and under the condition that the second MCU checks successfully, the unpacked OTA data in each second unpacking information is integrated and stored, so that OTA upgrading can be performed.

The second MCU performs the verification process, or performs the verification one by one according to the response information, or performs the whole packet verification according to the received sequence and the verification code, which is not described in detail.

Of course, the first MCU synchronizes the OTA data packet to be upgraded to the third MCU under the condition that the third MCU upgrading information is included in the OTA data packet to be upgraded, so that the third MCU performs OTA upgrading. That is, when the first MCU communicating with the gateway device receives the over-the-air OTA data packet to be upgraded and includes any other one, two or more MCUs upgrade information, the to-be-upgraded OTA data packet can be synchronized to the corresponding MCU, so that the corresponding MCU performs OTA upgrade.

Because only the first MCU can communicate with the gateway device, in some embodiments, after the second MCU performs OTA upgrade, the second MCU version information can be synchronized to the gateway device through the first MCU, so that the gateway device can synchronize with the APP in the user terminal through the OTA platform, and the user can know the upgrade condition in time. That is, the first MCU may receive the second MUC version information sent by the second MCU after the OTA upgrade is successful, and synchronize the second MUC version information to the gateway device.

It can be seen that, in the embodiment of the present disclosure, the node device includes two or more micro control units MCUs, so, after the first MCU receives an over-the-air OTA data packet to be upgraded sent by the gateway device and performs OTA upgrade, and when it is determined that the OTA data packet to be upgraded includes second MCU upgrade information, the OTA data packet to be upgraded can be synchronized to the second MCU, so that the second MCU performs OTA upgrade, thereby, OTA of two or more MCUs can be implemented at a time, multiple MCUs can be upgraded by multiple MCU node devices at a time, device upgrade efficiency in the node device network is improved, and resources are saved.

Of course, there may be two or more second MUCs in the node device, so that, when the OTA data packet to be upgraded includes the second MCU upgrade information, the OTA data packet to be upgraded is synchronized to the corresponding second MCU, so that the two or more second MUCs perform OTA upgrade, which is not specifically illustrated.
