uhf_c66_plugin

A flutter plugin for UHF type C66 to read UHF Cards. This was forked from the C72 plugin created by amorenew.

I included the newer API version from Chainway (2025-02-09) and updated the code for Flutter 3

Getting Started

• Import the library:

  import 'package:uhf_c66_plugin/uhf_c66_plugin.dart';

• Open connection to the UHF reader

  await UhfPlugin.connect();

• Check if is the reader connected

  await UhfPlugin.isConnected();

• Start reading data a single UHF card

  await UhfPlugin.startSingle();

• Start reading data multi 'continuous' UHF cards

  await UhfPlugin.startContinuous();

• Is started reading

  await UhfPlugin.isStarted();

• Stop Reading

  await UhfPlugin.stop();

• Close the connection

  await UhfPlugin.close();

• Clear cached data for the reader

  await UhfPlugin.clearData();

• Is Empty Tags

  await UhfPlugin.isEmptyTags();

• Write to EPC Tag

  await UhfPlugin.writeEPC(String writeData, String accessPwd)

• Set Power level (1 dBm : 30 dBm use string numbers)

  await UhfPlugin.setPowerLevel(String level);

• Get Power level (returns string number, 1-30 dBm)

  await UhfPlugin.getPowerLevel();

• Set Frequency mode (string number)

  • 1：China Standard(840~845MHz)
  • 2：China Standard2(920~925MHz)
  • 4：Europe Standard(865~868MHz)
  • 8：USA(902-928MHz)
  • 22：Korea(917~923MHz)
  • 50: Japan(952~953MHz)
  • 51: South Africa(915~919MHz)
  • 52: China Taiwan
  • 53: Vietnam(918~923MHz)
  • 54: Peru(915MHz-928MHz)
  • 55: Russia( 860MHz-867.6MHz)
  • 128: Morocco

  await UhfPlugin.setFrequencyMode(String area);

• Get Work area (returns string number)

  await UhfPlugin.getFrequencyMode();

• Listen to tags status

  UhfPlugin.tagsStatusStream.receiveBroadcastStream().listen(updateTags);

     List<TagEpc> _data = [];
     void updateTags(dynamic result) {
      setState(() {
          _data = TagEpc.parseTags(result);
       });
     }
