A method for retaining ble name and mac address in bluetooth firmware upgrade

Abstract

The present invention relates to the technical field of wireless communication, in particular to a method for reserving a BLE name and a MAC address in a Bluetooth firmware upgrade. The specific steps include: step 1 (S101), establishing an upgrade service connection between a mobile smart data terminal and a smart BLE device; step 2 (S102), the mobile smart data terminal reads the BLE name, MAC address and current version information of the connected smart BLE device; Step 3 (S103), the mobile smart data terminal selects the new firmware to be upgraded; Step 4 (S104), The mobile intelligent data terminal writes the BLE name and MAC address into a specific location of the firmware and recalculates the firmware data inspection value; Step 5 (S105), the mobile intelligent data terminal sends firmware data packets in sequence, etc. Beneficial effects: Solve the technical problem of BLE name and MAC address being wiped out due to smart BLE device firmware update in the existing related technologies, improve the security of data writing, prevent data from being modified and tampered at will, and effectively reduce upgrade costs .

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for reserving a BLE name and a MAC address in a Bluetooth firmware upgrade. Background technique [0002] With the increasing maturity of BLE (Bluetooth Low Energy) technology, BLE has been widely used in smart devices and smart controls. Currently, BLE smart devices commonly include smart boxes, smart Bluetooth speakers or smart lights that support the BLE protocol. Manufacturers need to update the firmware of BLE smart devices to fix product defects and add functions. The online upgrade method based on BLE has been widely used, which has the advantages of saving resources, saving time and effort compared to other methods. [0003] However, because the current equipment manufacturers generally incorporate the BLE name and the authorized MAC address code into the firmware and write them into the Bluetooth chip together, which increases the secu...
