器件型号：CC3135MOD 主题中讨论的其他器件： MSP432E401Y、 UNIFLASH
硬件：MSP432E401Y (时钟120MHz)+定制 PCB 上的 CC3135MOD
软件： CCSv12 + TI-RTOS + Simplelink WiFi 插件 v4.20
编译器版本：TIv20.2.6.LTS
当我更改 SL_WlanSetMode (Role_AP)-> SL_WlanSetMode (Role_STA)->然后返回-> SL_WlanSetMode (Role_AP)时、CC3135MOD 停止响应。
sl_Start (0、0、0)；长时间挂起、然后最终每次返回 SL_API_ABLETED (-2005)。 即使在 nRESET 或下电上电后也是如此。
恢复的唯一方法是使用 UNIFLASH 对映像进行重新编程。
我的应用程序需要进入 AP 模式、以便从器件托管本地网页、以便用户更改网页上的设置。 然后、在应用程序中的其他时间、它需要进入站点模式。 但是、当它尝试返回到 AP 模式时、模块就会变砖。
Simplelink 网络处理器文档(SWRU455L)说明每次更改角色时都要重新启动模块。 请查看以下代码并帮助我确定问题所在。
此时我需要进入 AP 模式：
