这样写读出来的数据会被覆盖掉，怎么解决，求助！

if (res.characteristics[i].properties.read) {

                console.log("readServicweId：", myUUID);

                console.log("readCharacteristicsId：", res.characteristics[i].uuid);

                that.setData({

                    characteristics:[

                        ...that.data.readCharacteristics,

                        {

                            readServicweId: myUUID,

                            readCharacteristicsId: "CEB5555A-55E1-5555-55F5-EA0736155555",

                        }

                    ]

                })

              }

              if (res.characteristics[i].properties.write) {

                console.log("writeServicweId：", myUUID);

                console.log("writeCharacteristicsId：", res.characteristics[i].uuid);

                that.setData({

                  writeServicweId: myUUID,

                  //writeCharacteristicsId: res.characteristics[i].uuid,

                  writeCharacteristicsId: "BEB5555A-55E1-5555-55F5-EA0736155555",//手动设置writeCharacteristicsId为这个UUID，为了方便写死在这里

                })

              }
