I have a problem in my project.
I tried to connect Smart Phone Hotspot with StationAp mode ESP8266 and station mode ESP8266.

This is stationAp mode ESP8266.

Code: Select all--init.lua
dofile("stationAp.lua")
dofile("webServer.lua")


Code: Select all--stationAp.lua
print("Ready to start soft ap AND station")
     local str=wifi.ap.getmac();

     wifi.setmode(wifi.STATIONAP)
     
     local cfg={}
     cfg.ssid="ESP8266_"..ssidTemp;
     cfg.pwd="1111111111"
     wifi.ap.config(cfg)

     cfg.gateway="172.20.10.1";
     wifi.ap.setip(cfg);
     
     wifi.sta.config("iPhone","sda342342")
     wifi.sta.connect()
     
     local cnt = 0
     gpio.mode(0,gpio.OUTPUT);
     tmr.alarm(0, 1000, 1, function()
         if (wifi.sta.getip() == nil) and (cnt < 20) then
             print("Trying Connect to Router, Waiting...")
             cnt = cnt + 1
                  if cnt%2==1 then gpio.write(0,gpio.LOW);
                  else gpio.write(0,gpio.HIGH); end
         else
             tmr.stop(0);
             print("Soft AP started")
             print("Heep:(bytes)"..node.heap());
             print("MAC:"..wifi.ap.getmac().."\r\nIP:"..wifi.ap.getip());
             if (cnt < 20) then print("Conected to Router\r\nMAC:"..wifi.sta.getmac().."\r\nIP:"..wifi.sta.getip())
                 else print("Conected to Router Timeout")
             end

             cnt = nil;cfg=nil;str=nil;ssidTemp=nil;
