ESP8266与NodeMCU AP网络掩码255.255.255.240

Question

在NodeMCU或ESP8266中是否存在任何问题，我们不允许将255.255.255.240作为AP的网络掩码？我将网络掩码配置为255.255.255.240，当我这样做时

if(wifi.getmode() == wifi.SOFTAP or wifi.getmode() == wifi.STATIONAP ) then
      ip, nm, gw = wifi.ap.getip()
      print("AP IP Info ip nm gw:",ip, nm, gw)
end

打印得像

一样

AP IP Info ip nm gw:    10.100.0.1      255.255.255.240 10.100.0.1

但是，连接到它的计算机（和其他ESP8266）的ifconfig显示网络掩码为255.255.255.0。

从我的笔记本电脑中取样ifconfig

wlp0s20u4u2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.100.0.2  netmask 255.255.255.0 broadcast 10.100.0.255
        inet6 fe80::225:22ff:fe4d:2691  prefixlen 64  scopeid 0x20<link>

任何想法或修复？

示例代码

apIPCfg={}
apCfg={}
   apCfg.ssid="abcdefgh"
   apCfg.pwd="abcdefgh12345678"
   apCfg.auth=AUTH_WPA2_PSK
   apIPCfg.ip='10.100.0.1'
   apIPCfg.netmask='255.255.255.240'
   apIPCfg.gateway='10.100.0.1'

   wifi.setmode(wifi.STATIONAP)
   wifi.ap.setip(apIPCfg)
   wifi.ap.config(apCfg)
