蓝牙重启后重新获取到的特征值属性，都是正常的，两个特征，一读一写，筛选没有错，就是读写都不行，必须重启，或者刷新小程序 获取特征UUID ok { "characteristics": [ { "uuid": "6E400003-B5A3-F393-E0A9-E50E24DCCA9E", "handle": 14, "properties": { "read": true, "write": false, "notify": true, "indicate": false, "writeNoResponse": false, "writeDefault": false } }, { "uuid": "6E400002-B5A3-F393-E0A9-E50E24DCCA9E", "handle": 17, "properties": { "read": false, "write": true, "notify": false, "indicate": false, "writeNoResponse": true, "writeDefault": true } } ], "errCode": 0, "errno": 0, "errMsg": "getBLEDeviceCharacteristics:ok"

ios要加services,安卓不用，但谷歌手机有没有都搜不到
