-### Q2: Sending I2S IN command is ineffective when WiFi is in slave mode
-
-<div class="grid" markdown>
-
-=== "Problem Symptoms"
-    1. After normal wiring and power-up, current mode shows USB, but sending I2S IN command has no effect
-
-=== "Possible Causes"
-    1. Firmware function limitations
-        - Current firmware does not support mode switching from WiFi (I2S slave) to XMOS (I2S master)
-
-=== "Problem Analysis"
-    1. Communication status
-        - Commands can communicate normally
-        - But mode switching function does not take effect
-    2. Function limitations
-        - Firmware has not implemented conversion function from WiFi slave mode to XMOS master mode
-
-=== "Solutions"
-    1. Modify connection method
-        - Mount WiFi module to Bluetooth module
-        - Implement mode switching function through Bluetooth module

-### Q2: WiFi做从模式时，发送IIS in指令无效
-
-<div class="grid" markdown>
-
-=== "问题现象"
-    1. 正常连线且上电后发送当前模式为USB，发送IIS in指令后无效果
-
-=== "可能原因"
-    1. 固件功能限制
-        - 当前固件不支持WiFi(IIS从)到XMOS(IIS主)的模式切换
-
-=== "问题分析"
-    1. 通信状态
-        - 命令可以正常通信
-        - 但模式切换功能未生效
-    2. 功能限制
-        - 固件未实现WiFi从模式到XMOS主模式的转换功能
-
-=== "解决方案"
-    1. 修改连接方式
-        - 将WiFi模块挂载到蓝牙模块上
-        - 通过蓝牙模块实现模式切换功能

-### Q3: 底板上电后，XMOS-A316模组未发送任何命令
-
-<div class="grid" markdown>
-
-=== "问题现象"
-    - 底板上电后，XMOS-A316模组没有通过串口发送命令
-
-=== "可能原因"
-    1. 供电异常
-        - 底板未给模组供电
-        - 焊接不牢固
-    2. 硬件连接问题
-        - 串口引脚连接错误
-
-=== "排查步骤"
-    1. 测量电压
-        - 检查模组的 0.9V、1.8V、3.3V 电压是否正常
-    2. 检查电源能力
-        - 0.9V 要求 1A 以上
-        - 3.3V/1.8V 要求 300mA 以上
-    3. 检查IO连接
-        - 对照硬件参考设计排查IO连接
-        - 对照规格书确认IO定义
