oppo r11，微信版本7.0.3 <picker @change="bindPickerChangeL" :value="indexL" :range="lanYaName"> <view class="uni-input">{{lanYaName[indexL]}}</view> </picker> bindPickerChangeL: function(e) { vm.indexL = e.target.value; vm.deviceId = vm.lanYaArray[vm.indexL]; ble.connectTO(vm, vm.deviceId, vm.readFunc, 128); },

低功耗都是不用输入pin的吗
