There are many function you can do just visit zk protocol to see the command and put it in executeCmd function already exist in the ZKLIB
-
[This repo contain the cmd of many machine ] (https://github.com/adrobinoga/zk-protocol/blob/master/protocol.md)
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, '')
