CC2541一主三从
请问:1.CC2541做主机的时候,能实现链接一个从机的状态下,再去扫描另外的从机?为什么我在连接一个从机的情况下就扫描不到其他广播的从机了?
2.CC2541做主机的时候,能否实扫描到多个从机后,手动控制连接多个从机,不是像例程间隔相同的时间依次连接多个从机,而是通过手动控制连接多个从机?
我看到的例子如下,推荐使用新一代2640做主机。

您好,能说下2541能否实现这样的功能?
宣称可以,但从没看到这样实现的产品,254x处理能力有限,即使可以连三个,也不会考虑用在实际产品中。但2640是可以实现你说的这种功能。

Use CC2541EM or CC2541 keyfob as BLE central device, can connect to maximum 2 SimpleBLEPeripheral devices and discover more than 2 characteristics on each peripheral device.
Based on BLE 1.3.2 version stack.
另外一条信息分享:
BlueGiga is a module vendor and has written their own BLE stack that runs onCC2540/41 which features up to 8 simultaneously connections.
However, I believe that BlueGiga's software is not royalty-free, which our TI stack is. You should contact BlueGiga for more information.
非常感谢,那请问这种功能CC3640有没有用在哪种具体的产品上
这个优点目前还没有太多客户用,蓝牙4.2的特性。我跑过这个例子,我试过做主设备连可以连3个从,同时,可以做从再连到一个手机,稳定,可以实现由你自己选择连接哪个从。
好的,我研究研究,非常感谢
