Run the example

  1. Install and run the gateway
  2. Download the Go client library
  3. Copy the root certificate of the gateway to your working directory. As default, the certificate(ca.crt) resides in cert of the installation directory.

  4. Change the gateway and the device information in src/example/wiegand/test/test.go as needed.

     // the path of the root certificate
 GATEWAY_CA_FILE = "../../../../cert/gateway/ca.crt"

 // the address of the device gateway
 GATEWAY_IP = "192.168.0.2"
 GATEWAY_PORT = 4000

 // the ip address of the target device
 DEV_IP = "192.168.0.110"
 DEV_PORT = 51211
 USE_SSL = false

  5. Build.

     cd src/example/wiegand/test
 go build .

  6. Run.

     ./test

1. Connect to the gateway and the device

The example assumes you use the device gateway. For the master gateway or other connection options, refer to the Connect or ConnectMaster examples.

  gatewayClient := &client.GatewayClient{}
  gatewayClient.Connect(GATEWAY_CA_FILE, GATEWAY_IP, GATEWAY_PORT)

  connectSvc = connect.NewConnectSvc(gatewayClient.GetConn())
  deviceID, _ := connectSvc.Connect(DEV_IP, DEV_PORT, USE_SSL)

2. Make the standard 26 bit format

The 26 bit standard format consists of 8 bit facility code and 16 bit id. It is one of the most widely used formats in the industry.

  // 26 bit standard
  // FC: 01 1111 1110 0000 0000 0000 0000 : 0x01fe0000
  // ID: 00 0000 0001 1111 1111 1111 1110 : 0x0001fffe
  // EP: 01 1111 1111 1110 0000 0000 0000 : 0x01ffe000, Pos 0, Type: Even
  // OP: 00 0000 0000 0001 1111 1111 1110 : 0x00001ffe, Pos 25, Type: Odd

  }

  std26bitFormat := &wiegand.WiegandFormat{
    Length: WIEGAND_26BIT_LENGTH,
    IDFields: [][]byte{

  wiegandSvc.SetConfig(deviceID, std26bitConfig)

3. Make the HID 37 bit format

The HID 37 format consists of 16 bit facility code and 19 bit ID.
