Cách sử dụng package

• install package npm i phenet-test-library

Khởi tạo command

• import

  import { ServiceManager } from 'phenet-test-library';
  import { ServicesName, PIDsName } from 'phenet-test-library';
  

• khởi tạo object service

  var service = new ServiceManager();
  

• khai báo command template:

  let cmd = JSON.parse('{"time": "null", "data": "", "type": ""}');
  

• append các pids cần request:

    service.appendCommandPID(PIDsName.Engine_speed, cmd);
    service.appendCommandPID(PIDsName.Vehicle_speed, cmd);
    service.appendCommandPID(PIDsName.Throttle_position, cmd);
    service.appendCommandPID(PIDsName.Odometer, cmd);
    service.appendCommandPID(PIDsName.VIN, cmd);
    service.appendCommandService(ServicesName.MODE_3_REQ_DTCS, cmd);
    service.appendCommandService(ServicesName.MODE_4_CLEAR_DTCS, cmd);
    service.appendCommandService(ServicesName.BAT, cmd);
    console.log(JSON. stringify(cmd, null, 2));
  

• kết quả print log:

   {
   "time": "9:4:24:136",
   "data": "2015:2:1:12:0:0:0:0:0/2015:2:1:13:0:0:0:0:0/2015:2:1:17:0:0:0:0:0/2015:2:1:166:0:0:0:0:0/2015:2:9:2:0:0:0:0:0/2015:2:3:0:0:0:0:0:0/2015:2:4:0:0:0:0:0:0/2015:2:88:0:0:0:0:0:0",
   "type": "Engine_speed/Vehicle_speed/Throttle_position/Odometer/VIN/MODE_3_REQ_DTCS/MODE_4_CLEAR_DTCS/BAT"
   }
  

Decode command nhận được từ ESP

• decode data nhận từ ESP (đã decrypt)

   // fake command
   let recv_cmd = JSON.parse(
      `{
         "time": "13:28:58:730",
         "data": "2024:3:65:12:18:52:0:0:0\
         /2024:16:20:73:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51;\
         /2024:16:20:67:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51;/"
      }`
   );
  
   // decode command
   let results = service.decode(recv_cmd);
   // print result
   console.log(JSON.stringify(results, null, 2));
  

• kết quả print log

   {
      "data": "1165/3FADP4FJ2BM113913/P0133;C0641;C0450;P3446;C01032;C02413;P3131;P3339;P3133",
      "type": "Engine_speed/VIN/MODE_3_REQ_DTCS"
   }

code example

import { ServiceManager } from 'phenet-test-library';
import { ServicesName, PIDsName } from 'phenet-test-library';

var service = new ServiceManager();

// ### Khởi tạo command (encode) ###
let cmd = JSON.parse('{"time": "null", "data": "", "type": ""}');

service.appendCommandPID(PIDsName.Engine_speed, cmd);
service.appendCommandPID(PIDsName.Vehicle_speed, cmd);
service.appendCommandPID(PIDsName.Throttle_position, cmd);
service.appendCommandPID(PIDsName.Odometer, cmd);
service.appendCommandPID(PIDsName.VIN, cmd);
service.appendCommandService(ServicesName.MODE_3_REQ_DTCS, cmd);
service.appendCommandService(ServicesName.MODE_4_CLEAR_DTCS, cmd);
service.appendCommandService(ServicesName.BAT, cmd);
console.log(JSON.stringify(cmd, null, 2));

// ### Decode ###
// fake command
let recv_cmd = JSON.parse(
  `{
