//  test code:

    let zkInstance = new ZKLib('192.168.1.201', 4370, 5200, 5000);
    try {
        // Create socket to machine
        await zkInstance.createSocket()


        // Get general info like logCapacity, user counts, logs count
        // It's really useful to check the status of device

        console.log(await zkInstance.getInfo())
      } catch (e) {
        console.log(e)
        if (e.code === 'EADDRINUSE') {

    })

        console.log(data)
    })

    // Get the current Time in the machine

    console.log(s);

    // Delete the data in machine
    // Note: You should do this when there are too many data in the machine,
          // this issue can slow down machine.

    zkInstance.clearAttendanceLog();


    // Disconnect the machine ( don't do this when you need realtime update :)))
    await zkInstance.disconnect()

}

test()  // in the end we execute the function

 

There are many functions you can just visit zk protocol to see the command and put it in executeCmd function already existed in the library. The function executeCmd accepts the command constant in constants.js and the data if needed, and we can implement it as follows:

    async executeCmd(command, data=''){
        return await this.functionWrapper(
            ()=> this.zklibTcp.executeCmd(command, data),
            ()=> this.zklibUdp.executeCmd(command , data)
        )
    }

    // unlock the door  
    executeCmd(CMD.CMD_UNLOCK, '')
