如何接收低功耗蓝牙消息
private BluetoothGattCharacteristic mNotifyCharacteristic; BluetoothGattService service = gatt.getService(UUID.fromString(serviceUuid)); mNotifyCharacteristic = service.getCharacteristic(UUID.fromString(characterUuid));Python numpy.fromstring函数方法的使用
NumPy（Numerical Python的缩写）是一个开源的Python科学计算库。使用NumPy，就可以很自然地使用数组和矩阵。NumPy包含很多实用的数学函数，涵盖线性代数运算、傅里叶变换和随机数生成等功能。本文主要介绍一下NumPy中fromstring方法的使用。 原文地址：Python numpy.fromstring函数方法的go 类型转换
测试用例 package code import ( "github.com/shopspring/decimal" ) //float64转成int64 func Float64ToInt64(s interface{}) int64 { var data int64 if s != nil { s1, ok := s.(float64) if ok { data = decimal.NewFro使用lxml的etree读取xml时的问题：ValueError: Unicode strings with encoding declaration are not supported.
ValueError: Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration. 原xml文件内容： <?xml version="1.0" encoding="UTF-8"?> <dataset name="Lara_UrbanSeq1" veLinux string转其他类型
