2: acquiring the content of the specified firmware block from the Bluetooth chip through the serial port;
3: and decrypting the acquired firmware block content. Encryption and decryption modes of firmware: taking 8 bytes of firmware data and specific 8 bytes of array data to carry out OR operation one by one, wherein the 8 bytes of array data are designated invariable;
4: burning the acquired firmware block content in a block form;
5: whether all the firmware blocks are successfully acquired and written in is judged, if yes, the step 206 is carried out, and if not, the step 202 is carried out;
6: and exiting the bootloader and running the new application code.
The invention has the beneficial effects that:
1. the dimmer function and the Bluetooth function are controlled by different mcus, so that the dimmer can be normally used in the Bluetooth upgrading process, the user experience can be improved, and the upgrading speed is increased;
2. when the Bluetooth and the dimmer firmware are integrated, the dimmer firmware is encrypted, so that the safety of equipment is improved;
3. even if the upgrading fails due to accidental operation during Bluetooth upgrading or Bluetooth firmware is damaged, the manual control of the dimmer is not influenced;
4. the upgrading of light modulator mcu opens up a backup area of upgrading inside the bluetooth chip, reads the information in this backup area when light modulator restarts at every turn, even unexpected outage when light modulator upgrades like this can not cause permanent trouble to light modulator yet, and it is more convenient to use, and stability reliability is higher.

Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, a method for upgrading a firmware of a dimmer based on a bluetooth Mesh network includes the following eight steps: 1) firstly, packaging the Bluetooth dimmer firmware to be upgraded, and integrating the packaged Bluetooth dimmer firmware into the Bluetooth firmware;
2) the Bluetooth firmware is upgraded, corresponding APP runs in the intelligent equipment, the upgrading state is manually entered, and the Bluetooth firmware packaged in the step 1 is transmitted to a Bluetooth chip through Bluetooth, so that the Bluetooth firmware is upgraded;
3) after the Bluetooth firmware upgrading is completed, the restarting dimmer intelligent equipment sends a restarting dimmer command;
4) after the bootloader executes the restarting of the dimmer, entering the bootloader for execution;
5) before the upgrading of the light modulator, the bootloader acquires the description information about the light modulator firmware in the Bluetooth chip through the serial port, and the firmware description information part comprises: whether a zone bit, a forced upgrading zone bit, a firmware version number, a firmware length, an initial address of firmware operation and the like are upgraded, wherein before the firmware of the light modulator is upgraded, the upgrading zone bit is not upgraded, when the light modulator upgrades the local firmware through a serial port, the upgrading zone bit is changed into yes to indicate that the firmware is upgraded, when the forced upgrading zone bit is not upgraded, whether the upgrading is needed is judged according to the firmware version number, and the firmware length is used for determining the length of the firmware to be burned;
6) before the dimmer is upgraded, the dimmer is confirmed to compare the acquired firmware description information with local firmware description information to determine whether the upgrade is needed;
7) and (3) upgrading the dimmer:
8) and after the upgrade is finished, the dimmer exits from the bootloader and is switched to the application program for execution.
The step 7 of upgrading the dimmer specifically comprises the following six steps;
1: starting upgrading;
2: acquiring the content of the specified firmware block from the Bluetooth chip through the serial port;
3: and decrypting the acquired firmware block content. Encryption and decryption modes of firmware: taking 8 bytes of firmware data and specific 8 bytes of array data to carry out OR operation one by one, wherein the 8 bytes of array data are designated invariable;

5: whether all the firmware blocks are successfully acquired and written in is judged, if yes, the step 206 is carried out, and if not, the step 202 is carried out;
6: exiting the bootloader and running a new application code;
by adopting the method, the dimming function part of the Bluetooth dimmer and the Bluetooth Mesh function part are independently separated, different MCUs are adopted for control, serial ports are adopted for communication interaction between the dimming function part and the Bluetooth Mesh function part, dimmer firmware to be upgraded is encrypted, the related description information of the firmware is inserted, the processed dimmer firmware and the processed Bluetooth firmware are integrated and packaged, the related APP of the intelligent equipment enters upgrading through manual control, the packaged firmware is upgraded to a Bluetooth chip through Bluetooth wireless communication, and the APP controls to restart the dimmer. The method comprises the steps that after the dimmer is powered on every time, dimmer firmware description information is obtained from a Bluetooth chip through a serial port, the dimmer firmware description information is compared with local dimmer firmware description information, whether the local dimmer firmware is updated or not is determined, if the local dimmer firmware is determined to be updated by the dimmer, dimmer firmware is obtained from the Bluetooth chip through the serial port, a Flash area corresponding to the dimmer is written in, the local dimmer description information is updated, and therefore the Bluetooth dimmer is upgraded. As can be seen from the above upgrading method, each time the bluetooth dimmer is powered on and restarted, the new firmware description information is obtained and compared with the local firmware description information, so as to determine whether to upgrade. The Bluetooth firmware and the dimmer firmware are independently upgraded, so that the normal use of the dimmer is not influenced even if the Bluetooth is changed into a brick in the upgrading process. In addition, when the intelligent device updates the firmware through the Bluetooth, the light modulator can normally operate, and the user experience is not influenced. And, this method is better in upgrading speed than directly upgrading the dimmer firmware through bluetooth.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
