GattLib is a library used to access Generic Attribute Profile (GATT) protocol of BLE (Bluetooth Low Energy) devices. It has been introduced to allow to build applications that could easily communicate with BLE devices. It supports Bluez v4 and v5. ...

The snippet below is the example you can find in the sample, powered by two extension methods for brevity (deviceFor(…)anduseBasic { device, services -> … }). It also uses theGenericAccessobject, which is the definition of the standard Bluetooth GATT "Generic access". It includes extens...
为1个字节,根据Access Address第一个Bit,有两种取值情况:0x55或者0xAA(纯PHY层行为); 2. Access Address: 用来标示接收者ID或者空中包身份, 根据Access Address的不同,又区分两种Packet类型:广播包和数据包: ---广播包:广播包Access Address 固定为0x8E89BED6,广播包只能在广播信道(channel)上传输,即只能在37...

恒玄的芯片是没文档的。BES2500芯片有着资源大,代码乱等特点。最近用到了这里的BLE部分。又折腾了一把,伤筋动骨啊。不过,总算是搞定了。这里是要做个总结吧。 二 源码解析 关于ble广播: 代码语言:txt 复制 app_ble_custom_adv_write_data(BLE_ADV_ACTIVITY_USER_1, ...
Generic Access Profile(通用访问规范) 它在用来控制设备连接和广播,用于提供蓝牙设备的通用访问功能,包括设备发现、连接、鉴权、服务发现等等。 GATT是建立连接后通信规范, 而蓝牙是通过GAP建立通信的。 GAP 使你的设备被其他设备可见,并决定了你的设备是否可以或者怎样与合同设备进行交互。
一、BLE现在低功耗蓝牙(BLE)连接都是建立在GATT(GenericAttributeProfile)协议之上。GATT是一个在蓝牙连接之上的发送和接收很短的数据段的通用规范,这些很短的数据段被称为属性(Attribute)。二、 GAP 详细介绍GATT之前,需要了解 GAP(GenericAccessProfile),它在用来控制设备连接和广播。GAP 使你的 ...
