CC3235MODS 连接WiFi

您好

遇到一个问题，现在又一个应用场景，同一个路由器的2.4G和5G的SSID都是相同，密码也是相同的，或是2个路由器，SSID和密码相同，但是频道不同，一个是在2.4G频道中，一个是在5G频道中，2.4G的信号比较强-25dBm，而5G的信号时-40dBm，那么我们的模块（CC3235MS）是有些连接2.4G的还是5G，还是都连接不上呢？目前表现得结果就是2个都连接不上。

The connection scan is run before a connection attempt. The process starts by running a fast scan cycle.
Fast scan: the purpose of this scan is to scan select channels to find and connect to a proper AP without
scanning all 2.4G and 5G (and DFS) channels. Only select channels are scanned first, because a full scan
could be a very slow process (more than 3 seconds).
The first step in this process is to decide which channels will be scanned. This selection is done by a rank
algorithm which takes into account historical scan results, connection statues, link quality, and so forth.
After the Fast Scan completes, the system decides whether to connect to one of the candidates or to
continue with the regular connection scan.
The decision is based on attributes such as: Priority, Security settings, RSSI, channel, and whether the
candidate network was the last connected network. If a proper candidate was not found, the regular
connection scan will follow.
5G和2.4G都连不上？用手机开热点是否可以连接

可以的。
这几天又发现一个致命的问题
当路由器的DHCP设置为：192.168.150.（193~254），子网掩码设置为：255.255.25.0，网关地址设置为192.168.150.192 时候， CC3235MODS获得静态IP、子网掩码、网关都为192.168.150.0是什么原因呢？同时也采用官方例程AT_Command 时，情况也是一样的。
