Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the present invention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, with example, the present invention is described in further detail below in conjunction with the accompanying drawings, but example is not as a limitation of the invention.
As it is shown in figure 1, embodiments of the invention comprise the following steps:
S10, main equipment and bluetooth equipment set up wireless connections；
S20, main equipment carry out data transmission with bluetooth equipment；
S30, definition bluetooth equipment are at the storage organization of system firmware；
S40, system start upgrading by wireless technology.
Preferably, in step S20, the wireless data transmission of bluetooth equipment is as data transmission channel by the SPP agreement of bluetooth.
Preferably, in step s 30, makeing mistakes occurs when be to ensure that system upgrade in the storage organization of definition system firmware or power down suddenly causes system operation exception.
Preferably, in step s 40, comprise the following steps:
After S401, bluetooth equipment receive EWENTERUPDATE order, bluetooth equipment enters upgrade mode；
After S402, entrance upgrade mode, bluetooth master sends EWUPDATEFILEST, enters file and updates, and incoming filename to be updated；
S403, bluetooth equipment are started to update firmware information by EWUPDATEFILEDATA order, and the address of renewal is the data address of the backup that this document is corresponding；
After S404, EWUPDATEFILEEND order, specified file updates and terminates；
After S405, bluetooth equipment receive EWUPDATEEND order, system update terminates；
S406, file address and the backup address in file information storage region are exchanged, restarting systems simultaneously.
In the present embodiment, the firmware of system is mainly put on bluetooth master by the upgrading of the system firmware of bluetooth equipment, is connected with bluetooth equipment foundation by main equipment, by the SPP agreement of bluetooth, data is updated wirelessly on bluetooth equipment.
Two main contents it are mainly concerned with in the middle of this:
1, the transfer management of blue-teeth data；
2, the renewal of system firmware.
(1) management of Bluetooth data transfer
The wireless renewal of bluetooth equipment is as data transmission channel by the SPP agreement of bluetooth.
The SPP agreement of bluetooth, full name is Serial Port Profile, and i.e. at bluetooth protocol repertory common serial communication protocol achieved above, this communication tries two-way on principal and subordinate's bluetooth equipment.Mobile phone and the PC of Android is the SPP communication protocol supporting bluetooth at present.
Data below form is used to communicate data communication when:
Command keyword: define a series of order, such as EWENTERUPDATE enters upgrade mode, and EWUPDATEFILEST starts to update file, and EWUPDATEFILEDATA updates file data and waits.
Current data packet timestamp: terminate the sequencing by data from main bluetooth equipment for distinguishing, the value of timestamp is the biggest, the most rearward, from bluetooth equipment is transferred to main equipment when, timestamp is the most in all senses, mainly from master transmissions data to the most meaningful when of from equipment for packet.
The timestamp of last packet: for finding a packet loss of data when.
Data length: the data length of current transmission.
Data check and: for verify current data the most correct.
Data: the data content of transmission, are 2K byte to the maximum.
(2) storage mode of system program
In order to occur the when of ensureing system upgrade makeing mistakes or power down suddenly causes system operation exception, bluetooth equipment has done special handling in terms of the storage of system firmware, and the storage organization of the firmware of system is as follows:
| System boot program | File information storage | Firmware A | Firmware A backs up | Configuration file B | Configuration file B backs up | …… |
System boot program: the bootstrap of storage system firmware, fixed bit 32K size.Can automatically load this program after system boot start, this program can follow up the different firmware of the content choice in file information storage region and configuration file loads
File information storage: the relevant information of the system file of record storage, specifying information includes:
File number: record has how many files (not very backing up) in being currently up
File size: the length of record current file
File address: the record initial address that store on equipment of current file, can be from the firmware required for the loading of this address or configuration information when that system being run
Backup address: the backup address that record current file stores at equipment
Filename: the name of record current file
Alternative document storage information: if unnecessary one of file number, the storage information of alternative document can be stored below in the same format
Firmware A and firmware A backup: the firmware that system is run, content both system burning for the first time when is identical, and the file address about firmware in file information storage region is the storage position of firmware A, backup address is the address of firmware A backup.The loading of system boot is the address of the file being file information storage region all the time, and the firmware that system start-up i.e. for the first time loads is firmware A.The content of firmware A backup can be updated during having upgraded, update the file address of corresponding adnexa in file information storage region after having updated, so descend subsystem will load the adnexa in adnexa A backup region starting when thus complete the upgrading of adnexa.
Configuration file B and configuration file B backup: system run configuration information, storage and upgrading mode be consistent with firmware
(3) system wireless update flow process
Upgrading main flow is as follows:
After A, bluetooth equipment receive EWENTERUPDATE order, bluetooth equipment enters upgrade mode；
After B, entrance upgrade mode, bluetooth master sends EWUPDATEFILEST, enters file and updates, and incoming filename to be updated；
C, bluetooth equipment are started to update firmware information by EWUPDATEFILEDATA order, the data address that address is the backup that this document is corresponding updated, change of address is the backup address starting filename incoming when updating at the file of file information storage range searching respective file name；
After D, EWUPDATEFILEEND order, specified file updates and terminates；
After E, bluetooth equipment receive EWUPDATEEND order, system update terminates, and needs this time to exchange file address and the backup address in file information storage region, the update action of completion system, simultaneously restarting systems.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.Multiple amendment to these embodiments will be apparent from for those skilled in the art, and generic principles defined herein can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
