Abstract

The invention discloses a method for upgrading the firmware of a dimmer based on a bluetooth mesh network. The dimmer function and the bluetooth function are controlled by different MCUs, so that in the process of upgrading the bluetooth, the dimmer can be used normally, which not only can Improve user experience and upgrade speed. Encrypting the dimmer firmware when integrating Bluetooth and dimmer firmware will help improve the security of the device. Unexpected operations during Bluetooth upgrade cause upgrade failure or Bluetooth firmware damage , does not affect the manual control of the dimmer, the Bluetooth chip opens up an upgrade backup area for the dimmer mcu upgrade, and the dimmer reads the information of the backup area every time it restarts, so that even if the dimmer is accidentally interrupted during the upgrade Electricity, it will not cause permanent failure to the dimmer, it is more convenient to use, and the stability and reliability are higher.

Description

technical field [0001] The invention belongs to the field of intelligent lighting control, in particular to a method for upgrading the firmware of a dimmer based on a Mesh network. Background technique [0002] With the introduction of Bluetooth Low Energy (BLE) technology and the promotion of Bluetooth Mesh technology, in the field of intelligent lighting control, the types of Bluetooth dimmers based on Bluetooth Mesh technology are becoming more and more abundant, and the diversification of Bluetooth dimmer products and The mass popularity of the product makes it necessary to upgrade and optimize the product function in the process of using the bluetooth dimmer. Therefore, it is necessary to ensure the reliability and convenience of product upgrades. At present, the Bluetooth dimmer based on Bluetooth Mesh technology mainly upgrades the dimmer firmware online through the Bluetooth module. This method can realize the upgrade of the dimmer firmware. But there are also big d...
