Abstract

The invention discloses a light modulator firmware upgrade method based on a Bluetooth Mesh network. A light modulator function and a Bluetooth function are controlled by using different MCUs, so that the light modulator can be normally used in the process of upgrading the Bluetooth, the user experience is improved, and the upgrade speed is further improved; when the Bluetooth is integrated with the light modulator firmware, the light modulator firmware is encrypted to improve the security the equipment, the manual control of the light modulator cannot be influenced by the failed upgrade or Bluetooth firmware damage caused by the accident operation in the Bluetooth upgrade; a upgrade backup area is developed for the light modulator MCU upgrade in a Bluetooth chip, the information of the backup area is read when the light modulator is restarted each time; the permanent fault cannot occur on the light modulator even if the power is accidently failed in the upgrade of the light modulator; the use is more convenient, and the stability and the 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...
