Is it the same when wifi scanning is disabled? (wifiScan settings key)

kiralikbeyin · 2019-05-31T20:54:13Z

Yes.. I am trying to solve this problem since May 15.

mcspr · 2019-05-31T22:11:42Z

Does it reconnect after wifi.reset terminal command?
Do you use WebUI or telnet frequently with rfbridge? I do see that there is a check for connected clients in wifiReconnectCheck(). Perhaps, it stalls reconnection even without active websocket or telnet clients.

btw I did see the edit about the verision. lets mention that the version we are testing is 1.13.6-dev @ 820d8c4

    if (getSetting("ssid" + String(i)).length() == 0) break;
    if (getSetting("ip" + String(i)).length() == 0) {
      jw.addNetwork(
        getSetting("ssid" + String(i)).c_str(),
        getSetting("pass" + String(i)).c_str()
      );
    } else {

  jw.enableScan(getSetting("wifiScan", WIFI_SCAN_NETWORKS).toInt() == 1);

  unsigned char sleep_mode = getSetting("wifiSleep", WIFI_SLEEP_MODE).toInt();
  sleep_mode = constrain(sleep_mode, 0, 2);
  DEBUG_MSG_P(PSTR("[WIFI] RESET 15\n"));

  WiFi.setSleepMode(static_cast<WiFiSleepType_t>(sleep_mode));  
}

i think jw.setConnectTimeout(WIFI_CONNECT_TIMEOUT); is making trouble.

  jw.disconnect();

why debug screen stops at [023608] [WIFI] RESET 111
i cant understand.

kiralikbeyin · 2019-06-01T14:55:38Z

when it is connected to router and wifi.ap, it starts in AP mode and didnt connect to router.. Which is my problem :)

kiralikbeyin · 2019-06-01T15:57:57Z

i think this will help

void wifiReconnectCheck() {
  bool connected = false;

  if (WiFi.status() == WL_CONNECTED)
  {
    connected = true;
  }

  if (!WiFi.isConnected())
  {
    connected = false;
  }
  
  //#if WEB_SUPPORT
  //  if (wsConnected()) connected = true;
  //#endif
  //#if TELNET_SUPPORT
  //  if (telnetConnected()) connected = true;
  //#endif
  DEBUG_MSG_P(PSTR("[WIFI] wifiReconnectCheck() \n"));

  jw.setReconnectTimeout(connected ? 0 : WIFI_RECONNECT_INTERVAL);
  DEBUG_MSG_P(PSTR("[WIFI] %u \n"), connected);

}

It reconnects to router if connection drops and changes to AP mode..

@xoseperez maybe you can commit if this doesnt break other codes... i read about sonoff basic problem like this..

mcspr · 2019-06-01T21:07:04Z

@kiralikbeyin You missed my original question about the websockets or telnet, but I hope you had noticed their purpose. If either ws or telnet client objects are still there, wifi AP will stay up.

Note that it will reconnect eventually, if neither of them are connected. That is the intended behaviour.
Whenever telnet client is disconnected:

espurna/code/espurna/telnet.ino

Line 44 in 9ceca44

wifiReconnectCheck();

Whenever ws is disconnected:

espurna/code/espurna/ws.ino

Line 442 in 9ceca44

wifiReconnectCheck();

Which may not ever happened, based on the bug description. Either because of onDisconnect / onTimeout not firing or whatever else is not handled properly (comething Core does not do, or something we must do or check)
edit: And I hope this at least can be worked around by something as simple as closing the client manually.

By your proposal, it will drop any connected clients immediately, because softAP will be brought down.

mcspr · 2019-06-01T21:10:04Z

And if by wifi.ap you mean terminal command, it think it is missing a wifi.sta counterpart, because it disables STA mode completely within justwifi.

espurna/code/espurna/wifi.ino

Lines 551 to 562 in 9ceca44

    
           void wifiStartAP(bool only) { 
        
               if (only) { 
        
                   jw.enableSTA(false); 
        
                   jw.disconnect(); 
        
                   jw.resetReconnectTimeout(); 
        
               } 
        
               jw.enableAP(true); 
        
           } 
        
           void wifiStartAP() { 
        
               wifiStartAP(true); 
        
           }
