使用基于w600的 TW-03模组 扫描不到ap

[xupenghu]

先使用自带的AT固件，可以扫描到ap信息并连接，AT 固件log如下所示：

AT+CWLAP

+CWLAP:(4,"浜旀ゼ鏃犵嚎缃戠粶",-89,"24:69:68:ed:43:38",1) +CWLAP:(4,"www.ghtech.cn",-51,"c8:3a:35:74:51:20",2) +CWLAP:(4,"CMCC-QeZM",-59,"f8:48:fd:b1:c8:a8",2) +CWLAP:(3,"PDCN",-52,"74:7d:24:ea:45:be",6) +CWLAP:(0,"TP-LINK_F55C",-85,"50:bd:5f:73:f5:5c",6) +CWLAP:(4,"yitai123",-93,"c8:3a:35:6d:6b:28",10)

OK

AT+CWJAP="www.ghtech.cn","123wu123"

WIFI CONNECTED WIFI GOT IP

OK

然后下载此sdk的16_iot_wifi_manager例程，rtconfig.h中的宏已更改为w600 使用wifi scan命令 只扫描到一个ap, log如下：

扫描到的这两个ap 信道都是1 而且有时候能扫到 有时候又没有

[xupenghu]

特地将路由器信道该为1 然后扫描 发现能扫到 而且连接正常 ping外网也能通 所以怀疑是只能扫描1信道的热点

您好，更换SDK前，请勾选下载前擦除，这个问题是因为AT兼容固件的WiFi参数结构体和RTT的WiFi参数结构体不一样导致的。后续出货的兼容版本已经修复这个问题。

好的 验证已🆗 谢谢支持
