CC3200 AP模式下，怎么实现连接多个设备，怎么主动断开连接？

TI的工程师，你好！

   CC3200 AP模式下

   1.怎么实现连接多个设备

   2.怎么主动断开连接？

  能否提供些思路？需要用到哪些API？

  谢谢！

目前CC3200是configuration AP，只是支持一个设备连上了做配置，不支持多台设备。

您好！

          那下一次sdk更新会支持AP连接多个设备吗？

Frank,

这不是SDK更新版本的问题了，需要芯片版本更新才能支持，目前已在计划中，出来后TI会有推送信息发给各位的。谢谢！

TI 工程师，您好：

        您的意思是CC3200作为AP时，同一时刻只能连接一个STA？无法实现多个STA之间相互切换吗？

        那么CC3100呢？CC3100也是可以作为AP的，它可以实现同一时刻同时连接多个STA的功能吗？或者多个STA直接可以相互切换吗？

目前版本的CC3100和CC3200都之只能实现做AP时，连接一个SAT的功能。

如果要切换的话，这个可以通过软件去实现。

那STA模式，能建立多少个连接，或者说支持多少个TCP 套接字？

Hi SZ1,

         现在是否有新的CC3200芯片，当它做AP时候，可以支持接入4个STATION。谢谢！

TI后面会有CC3200的升级芯片推出，最大可支持4个Station，请关注TI的官网资料介绍。

请问现在最新的芯片支持多个设备连接了吗？哪里可以查到最新的信息？

目前的芯片还是支持一个设备连接，最新的信息就是在ti.com上搜索CC3200就可以获得了。

请告知具体查询位置。我在ti.com上搜索CC3200读了器件描述，没有找到哪个位置有写能接入1个设备或者4个设备。现在我们想开发接入4个设备的产品，因此需要确认该器件是否升级过，最好得到官方的数据。谢谢。

如果要支持连接4个设备，建议使用CC3200的升级芯片CC3220，这颗芯片可以支持4个Station的连接，而且还有CC3220SF版本内置了1M的Flash空间给客户使用

并且新的CC3220支持IPv6。
