Detailed Description
The core of the application is to provide a device upgrading method, a system, a device and a computer storage medium, which can avoid that the pause time of the MCU of the second device is larger than the connection gap, ensure that the MCU of the second device can respond to the timing interruption every time, and avoid the problem that the first device and the second device are disconnected due to asynchronous frequency hopping in the upgrading process.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of an apparatus upgrading method provided in the present application, where the apparatus upgrading method includes:
s101: receiving a connection gap expansion request sent by first equipment, wherein the connection gap expansion request comprises a target connection gap;
first, a first device and a second device are described, where the first device and the second device are in a pairing relationship, one first device may be paired with multiple second devices, and the first device sends an upgrade request to the second device to be upgraded, respectively.
Specifically, when the first device receives a request of upgrading the second device from the user, the first device sends a request for enlarging a connection gap to each of the second devices paired with the first device, where the request for enlarging the connection gap includes a target connection gap, and the target connection gap is determined according to the number of bytes of valid upgrade data in the upgrade request packet, and it is required to ensure that the target connection gap is longer than the time for writing the upgrade data.
S102: expanding the current connection gap into a target connection gap, and sending response information to the first equipment so that the first equipment can expand the actual connection gap between the first equipment and the second equipment to be upgraded;
s103: and when an upgrade request packet sent by the first device is received, executing write-in operation, wherein the write-in operation comprises writing the upgrade data in the upgrade request packet into the target flash, and the time of the write-in operation is less than the target connection gap.
Specifically, after receiving the request for enlarging the connection gap sent by the first device, the second device enlarges the current connection gap to a target connection gap, so that the second device can complete receiving and transmitting actions in one connection gap, and has sufficient time to complete writing operation, thus ensuring that the MCU in the second device can respond to the timing interruption every time, and avoiding the problem of asynchronous update frequency bands.
Assuming that the target connection gap in the received request for expanding the connection gap is 6ms and the current connection gap is 2ms, the connection gap of the device itself is adjusted from 2ms to 6ms, and the target connection gap is determined according to the byte number of the effective upgrade data in the upgrade request packet, so that the second device can be ensured to write the upgrade data in the expanded target connection gap, and the problem that the write flash duration is longer than the connection gap of the second device to cause loss of timing interruption is avoided. Furthermore, after the second device sets the connection gap of itself, the second device sends response information to the first device, so that the first device enlarges the actual connection gap between itself and the second device to be upgraded, the connection gap between the first device and the second device not to be upgraded is not adjusted, the target connection gap of each second device is matched with the actual connection gap of the first device, and therefore, in different connection gaps, the two parties performing data transmission can synchronously hop frequency according to the frequency bands in the communication list.
As an optional embodiment, when all the n second devices are to-be-upgraded second devices, n is an integer greater than 1, the target connection gaps of all the to-be-upgraded second devices are the same, and the actual connection gaps between the first device and each of the to-be-upgraded second devices are 1/n target connection gaps.
Assuming that the first device has two paired second devices, wherein the second device a is a second device to be upgraded and the second device B does not need to be upgraded, if the connection gap between the first device and the second device a is 1ms and the connection gap between the first device and the second device B is 1ms during normal data transmission, in the upgrading process, the connection gap between the first device a and the second device B is adjusted to be a target connection gap of 6ms, and the connection gap between the first device and the second device a needs to be expanded to be 5ms, while the connection gap between the first device and the second device B remains unchanged and still remains to be 1ms, correspondingly, assuming that the second device a and the second device B are both devices to be upgraded, after the connection gap between the first device a and the second device B is adjusted to be the target connection gap of 6ms, the connection gap between the first device and the second device a needs to be expanded to be 3ms, the connection gap of the first device and the second device B is also enlarged to 3ms to ensure the matching of the connection gap. Under the second scheme, because the first device and the second device to be upgraded are relatively independent in each connection gap, a plurality of second devices to be upgraded can be upgraded simultaneously.
Of course, the setting of the connection gap needs to be determined according to the number of effective upgrade data bytes in the upgrade package, and if the number of effective upgrade data bytes in the upgrade package is too large, the connection gap can be set to be larger.
It can be seen that, in this embodiment, when a first device needs to upgrade a second device paired with the first device, a connection gap of the second device is expanded to a target connection gap, and the connection gap between the first device and the second device to be upgraded is expanded, and the target connection gap of the second device is greater than a time for writing upgrade data in a flash, so that a pause time of an MCU of the second device is prevented from being greater than the connection gap, it is ensured that the MCU of the second device can respond to a timer interrupt every time, and a problem of disconnection due to asynchronous frequency hopping of the first device and the second device in an upgrading process is prevented.

and when an upgrade start package sent by the first equipment is received, erasing all the multiple pages of the flash in the backup area, wherein the multiple pages of the flash in the backup area comprise the target flash.
Specifically, when the upgrade is started, the first device firstly issues an upgrade start packet, the second device immediately erases all the multiple pages of flash in the backup area after receiving the packet, after the erase is completed, the first device and the second device have the problem of frequency band asynchronization, then the first device and the second device are disconnected and connected back to back, the backup area is completely erased before the formal upgrade is not started, and then the disconnection and connection back to back is currently used for avoiding the problem that the flash is erased in the upgrade process, so that the synchronous frequency hopping cannot be realized. Further, the upgrade start packet may also be issued only to the second device to be upgraded.
As an alternative embodiment, the process of expanding the current connection gap to the target connection gap includes:
expanding the current connection gap to a target connection gap at appointed time;
the process that the first device enlarges the actual connection gap between the first device and the second device to be upgraded comprises the following steps:
and the first equipment enlarges the actual connection gap between the first equipment and the second equipment to be upgraded at the appointed time.
Specifically, when the first device receives an upgrade command sent by the AP, the first device sends the command to the second device paired with the first device, and when the second device receives the command, the respective connection gap is set to the target connection gap, and the two devices synchronously switch the size of the connection gap at regular time and after a predetermined time, so as to achieve the purpose of synchronous frequency hopping. When part of second equipment is upgraded, after synchronous frequency hopping, the first equipment starts to transmit an upgrade request packet to the second equipment to be upgraded, the second equipment which is not upgraded normally reports feedback data, and the infrared lamp is normally synchronized, so that the first equipment can still normally track the second equipment which is not upgraded, and a user can still normally use the second equipment which is not upgraded.

In addition, a user can set one handle or two handles to be upgraded according to selection in the upgrading process, if only one handle is upgraded, the other handle can be normally used, and the user experience effect is improved.

and the upgrading module 3 is configured to execute a write operation when receiving an upgrading request packet sent by the first device, where the write operation includes writing upgrading data in the upgrading request packet into the target flash, and a time of the write operation is less than a target connection gap.
