haas506 2.0开发教程-example-蓝牙多设备扫描案例说明蓝牙信息克隆1.手机蓝牙改名信息克隆代码测试案例说明
开发板扫描蓝牙设备获取并打印蓝牙设备mac地址。mac地址每个设备不同且不能更改。本案例仅适用于M320开发板和HD1-RTU。案例使用手机与iBeacon作为从机。开发板根据设备名称进行连接要同时扫描到2个设备手机的蓝牙名称需要改成与iBeacon相同的名称。
蓝牙信息克隆
使用手机克隆iBeacon的名字信息。
1.手机蓝牙改名
手机下载nRF connect蓝牙调试工具。 iBeacon设备名称将手机蓝牙改成一样的名字
选择ADVERTISER后点击图标改名 信息克隆
点开iBeacon设备后点击CLONE 这样就得到了2个同名的设备。
代码
注意更改代码中的设备名称
