How to add a user with fingerprint

[ChiKaLiO]

Hello, i'm new to zk this library is worth gold to me but still can't figure alot of things.. i will be needing to add users from computer with fingerprints, bulk delete expired users

[ChiKaLiO]

The original lib not working, i can't figure out how to add a user, here is what i did: constants.js added CMD_SET_USER:8, zklibtcp:

async createUser(user) {
    console.log(user);
        return await this.executeCmd(COMMANDS.CMD_USER_WRQ, [user])

 }

index:

 const user = {
        uid: '90909',
        password:'',
        name: 'testing',
        user_id: '123',
        cb :''
    }
    await zkInstance.createUser(user);

i can't figure it out..

Yeah, I really tried to figure it out , but it just worked with some devices :)) so I haven't push it here

I tried every library in github 😆 i added cardno in one of the php libs and it worked but still can't figure out how to send the data i node..

i got it to work like this:

async setUser(uid, userid, name, password, role = 0, cardno = 0) {
    try{
    if (
      parseInt(uid) === 0 ||
      parseInt(uid) > 3000 ||
        userid.length > 9 ||
        name.length > 24 ||
        password.length > 8 ||
        cardno.length > 10
    ) {
        return false;
    }

      const command_string = Buffer.alloc(72);
      command_string.writeUInt16LE(uid, 0);
      command_string.write('2', 2, 1);
      command_string.write(password, 3, 8);
      command_string.write(name, 11, 24);
      command_string.writeUInt32LE(cardno, 35);
      command_string.writeUInt16LE(role, 39);
      command_string.writeUInt32LE(0, 40);
      command_string.write(userid ? userid.toString(9) : '', 48);

    console.log(command_string);
    return await this.executeCmd(COMMANDS.CMD_SET_USER, command_string);
  }catch(e){
    console.log(e);
    console.log('duh');
  }

    }

but the role is unkown, i dunno why .. my device is MB2000

    console.log(command_string);
    return await this.executeCmd(COMMANDS.CMD_SET_USER, command_string);
  }catch(e){
    console.log(e);
    console.log('duh');
  }

  }

but the role is unkown, i dunno why .. my device is MB2000

in this format everything is working:

const command_string = Buffer.alloc(72);
      command_string.writeUInt16LE(uid, 0);
      command_string.writeUInt16LE(role, 2);
      command_string.write(password, 3, 8);
      command_string.write(name, 11, 24);
      command_string.writeUInt16LE(cardno, 35);
      command_string.writeUInt32LE(0, 40);
      command_string.write(userid ? userid.toString(9) : '', 48);
