The driver is currently works well on Aliyun Iot Platform, you need to setup Aliyun Enviroment, connect Dlt meter on the serialport of linkedge gateway before using it. 8 | 9 | ## Operation Guide on Aliyun Iot Platform 10 | 11 | See Aliyun [linkedge-thing-access-websocket_client_sdk](https://github.com/aliyun/linkedge-thing-access-websocket_client_sdk/blob/master/protocol-design-description.md?spm=a2c4g.11186623.2.11.7afd760b9SsoxB&file=protocol-design-description.md) for the protocal details to connect device with Aliyun Linkedge Gateway. 12 | 13 | Currently the Driver only support "onlineDevice","reportProperty" and "getProperty" methods, the rest methods are to be updated. 14 | 15 | First of all,you need to create a DLT product and devices on [aliyun Iot platform](https://help.aliyun.com/document_detail/73705.html?spm=a2c4g.11174283.2.11.3a8b1668L08yIP).See [model.json](src/model.json) for detailed product properties. 16 | 17 | To use this driver you need to install an Aliyun Linkedge Gate way following [Official Instruction](https://help.aliyun.com/document_detail/102729.html?spm=a2c4g.11186623.6.560.18ab760b5ENITn), and [deploy a WebSocket driver](https://help.aliyun.com/document_detail/122583.html?spm=a2c4g.11186623.6.574.119c71b8bCk3oA).Currently the driver is tested only under Unbuntu 18.04 platform. 18 | 19 | ## To Use 20 | 21 | 1. In [config.json](src/config.json), setup the serialport information as well as the dlt meters. If you are using linux **portName** field just fill like ttyS1 or ttyUSB1 the driver will parse it to /dev/ttyS1, otherwise in windows just use COM1,COM2 (not testified). 22 | 23 | 2. If you have changed default aliyun WebSocket server (ip address and port number), update [server.json](src/server.json) file. Currently TLS support is not available. 24 | 25 | 3. If you want to support more DLT 645 properties, update the [model.json](src/model.json) file, please be sure to modify the propertyCode in [dltparser](src/dltparser.js) too so as the driver can parse relative property properly. 26 | 27 | 4. For aumomated installation download install.sh file first or copy the contents, run install.sh script to finish project installation, if you want to install node global, uncomment the global install file and comment nvminstallation file. If you are out of China, please comment the cnpm installation line and use npm directly. 28 | 29 | 5.
