我发送AT+MLWULDATAEX=145,68383635333532303330363735353938c80001007a01002134363031313330313533313736383401000706050403020113060b00002e000350dd00270000ea6000000000000000000000000000004300270001005604b6085301570064000000000000de00290000000007d0020fe04ab61b820000000000010314ffff43544e4200000000000000000000000000003216,0X0001他直接返回：ERROR

然后我用AT+MLWULDATASTATUS? 查询
返回：+MLWULDATASTATUS:0
手册说的是：未发送
有没有大神说下白

查询一下LWM2M的注册状态看看是否注册成功 AT+NMSTATUS?
在此状态：MO_DATA_ENABLED 下才能发数据
