Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the present application described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In order to solve the above problems, an embodiment of the present invention provides a firmware upgrading method based on bluetooth network topology, which is applied to a bluetooth host, as shown in fig. 1, and the method includes:
step S101, obtaining a target address of firmware to be upgraded;
step S102, comparing the target address with the addresses of the Bluetooth host, the Bluetooth relay and the Bluetooth slave, and determining the level to which the target address belongs;
step S103, adjusting parameters of firmware to be upgraded according to a preset protocol;
step S104, the adjusted parameters are sent to the upper level of the hierarchy to which the target address belongs according to the preset Bluetooth network topology structure, and the target address is controlled to upgrade the firmware of the target address.
Specifically, the terminal sends a target address of firmware to be upgraded, wherein the target address can be an address of a Bluetooth slave to be upgraded, a Bluetooth host address or a Bluetooth relay address, and the determination mode is mainly that the target address is compared with addresses of a Bluetooth host, a Bluetooth relay and a Bluetooth slave to determine a hierarchy to which the target address belongs, and the hierarchy is divided into a Bluetooth host layer, a Bluetooth relay layer and a Bluetooth slave layer. If the target address to be upgraded is a Bluetooth host, the Bluetooth host is directly subjected to firmware upgrading by utilizing an SPI/UART according to a terminal communicated with the Bluetooth host, if the target address to be upgraded is a Bluetooth relay, the relay is subjected to firmware upgrading by utilizing the prior art, and if the target address to be upgraded is a Bluetooth slave address, a Bluetooth network topology structure table preset according to the embodiment of the invention searches for the Bluetooth slave to which Bluetooth relay belongs to and confirms that the Bluetooth relay is in network connection. Wherein the bluetooth network topology table is shown in fig. 2. The upper level of the hierarchy to which the target address belongs can be understood as follows: when the level of the target address is a Bluetooth host layer, the upper level is a terminal, the adjusted upgrade parameters are directly sent to the Bluetooth host at the moment, the Bluetooth host upgrades the firmware of the Bluetooth host according to the upgrade parameters, if the level of the target address is a Bluetooth relay layer, the upper level of the Bluetooth relay is the Bluetooth host, at the moment, according to the communication protocols of the Bluetooth host and the Bluetooth relay, the Bluetooth host sends the adjusted upgrade parameters to the Bluetooth relay, the Bluetooth relay upgrades the firmware of the Bluetooth host, if the level of the target address is a Bluetooth slave layer, the upper level of the Bluetooth slave is the Bluetooth relay, at the moment, the adjusted parameters are sent to the Bluetooth slave according to the Bluetooth relay, the Bluetooth slave upgrades the firmware of the Bluetooth host, and the upgrade result is fed back upwards in sequence until the terminal.
Renegotiation of firmware update communication parameters according to a preset protocol is a common communication protocol in the prior art, and is not described herein.
According to the embodiment of the invention, according to a complex Bluetooth network topological structure, all Bluetooth slave node firmware can be updated through one entrance in a layered upgrading mode, so that the effect of rapid upgrading is achieved.
Based on the content of the above embodiments, as an alternative embodiment: the adjusting of the parameters of the firmware to be upgraded according to the preset protocol comprises the following steps:
determining the connection state of the hierarchy to which the target address belongs;
if the connection is normal, the parameters of the firmware to be upgraded are adjusted by using a preset protocol.
Specifically, it is determined that the current target address belongs to a hierarchy which is in a connection state, and parameters of the firmware to be upgraded can be adjusted by using a preset protocol.
Based on the content of the above embodiments, as an alternative embodiment: the method further comprises the steps of:
and storing the adjusted parameters and the target address of the firmware to be upgraded in a preset position.
Specifically, taking the example that the target address to be upgraded is a bluetooth slave: and receiving the adjusted parameters and the target address of the firmware to be upgraded at the Bluetooth relay, storing the adjusted parameters and the target address of the firmware to be upgraded at a preset position of the Bluetooth relay (the preset position is different from a file storage position of the Bluetooth relay for upgrading), transmitting the adjusted parameters into a Bluetooth slave corresponding to the target address, upgrading the firmware by the Bluetooth slave, feeding back a firmware upgrading result to a Bluetooth host, transmitting the result to a terminal by the Bluetooth host, and uploading the result to a cloud server.
Based on the content of the above embodiments, as an alternative embodiment: according to the preset Bluetooth network topology structure, the adjusted parameters are sent to the upper level of the level to which the target address belongs, and after the target address is controlled to upgrade the firmware, the method further comprises the following steps:
checking the firmware upgrading state by utilizing an algorithm;
if the verification is passed, a preset mark is set in Flash.
Specifically, after the transmission is completed, algorithm verification is performed, which is the same as the prior art. If the algorithm check is passed, a preset mark, namely a Valid mark, is set in Flash. It should be noted that, algorithm verification is common general knowledge, and it is needless to say that the verification work may be omitted, and the algorithm verification provided in the embodiment of the present invention belongs to a preferred implementation manner.
Under the condition that the target address is determined to be the Bluetooth slave, the Bluetooth relay periodically inquires a Valid flag in Flash, and if a Valid file to be upgraded exists, the steps S101-S104 are re-executed until the upgrade file finally reaches the Bluetooth slave to be upgraded, and the self-upgrade is completed. The embodiment of the invention allows the transmission failure to occur, and at this time, a retry mechanism can be started, for example, 3 times of retransmission are performed, and if the number of times limited by the retry mechanism is exceeded, the upgrade failure is indicated.
