After the world's first intelligent building appeared in the United States in 1984, the intelligentization of the home environment has become the mainstream of the current society. When the wireless communication module becomes the core communication point on each node of the smart home, the uniqueness of the smart home networking, who guarantees?
The current smart home system is based on wireless communication technology, and the networking between smart devices is the basis of the smart home system. A well-known manufacturer in the smart home industry selects the mainstream Zigbee communication standard for networking. The networking is based on the unique MAC address of the Zigbee chip for unique identification.
The internal MAC address of the Zigbee chip is a single-programmable (OTP) area. In order to facilitate maintenance and management of the device, the smart home manufacturer needs to modify the internal MAC address of the chip, associate the new MAC address with the smart device, and store it in the server. It is convenient for post-maintenance and upgrade. The MAC address is usually attached to the Zigbee module in the form of a bar code, such as:
In order to write the modified MAC address into the Zigbee chip, a programmer with bar code recognition capability is needed to identify and program it. Since the Zigbee chip is already packaged inside the module, it needs to be programmed online (post-patch). Modify the module content.
P800-ISP four-channel offline online programmer, P800 supports four-channel synchronous and asynchronous programming modes, which can be directly programmed from the PC. The machine comes standard with USB Host interface and can be connected to standard USB peripherals.
Because the P800-ISP supports standard USB peripherals and supports advanced function barcode gun modules, the combination of the two perfectly solves the manufacturer's MAC address mass production requirements. Users only need to configure dynamic data in the P800 project, add a barcode gun module, and configure the area where the MAC address is programmed, which is intuitive and operable. Such as:
After the configuration is complete, the barcode gun module becomes a source of data input. In the burning interface of the mass production mode, the P800 will pop up a prompt box to prompt the user to input the barcode, such as:
After seeing the window prompt, you need to scan the 1D barcode on the Zigbee module with the barcode gun. After receiving the scanned barcode data, the machine will automatically program, without the user having to perform additional operations, which is convenient and easy.
In this way, the "uniqueness" of the smart home networking can be easily handled by the P800-ISP plus barcode scanner.
