SinricPro does not report lost connection in a timely manner

[lilbuzz]

Using WEMO MINI Esp32. Connected to SinricPro server using cell phone hotspot. I disable the hotspot, but calls to SinricPro.isConnected() continue to return true. This is true for more than 10 minutes. I am calling SinricPro.handle() in my loop, and then polling SinricPro.isConnected().

Here is some sample debug output:

I have tested this with delays over 10 minutes, but the call to isConnected still returns true until the hotspot is re-enabled.

Hi @lilbuzz

Are you using the sketch here for testing or your own sketch https://github.com/sinricpro/esp8266-esp32-sdk/blob/master/examples/Switch/Switch/Switch.ino#L94

  #if defined(ESP8266)
    WiFi.setSleepMode(WIFI_NONE_SLEEP); 
    WiFi.setAutoReconnect(true);
  #elif defined(ESP32)
    WiFi.setSleep(false); 
    WiFi.setAutoReconnect(true);
  #endif

[lilbuzz]

Yes I am. Here are the lines in my setup: // Assuming you want your ESP32 to act like any other client (STAtion) on your Wi-Fi WiFi.mode(WIFI_STA); // Store Wi-Fi configuration in EEPROM? Not a good idea as it will never forget these settings. WiFi.persistent(false); // Reconnect if connection is lost WiFi.setAutoReconnect(true); // Modem sleep when in WIFI_STA mode not a good idea as someone might want to talk to it WiFi.setSleep(false);

1. Set logging to Verbose (Tools -> Core Debug Level -> Verbose)
2. flash the example code
3. Connect ESP to Iphone14
4. Turn off Hotspot.
5. Disconnects immediately.
6. Reconnection does not seem to happen though. need to look into this.

I'm not sure what was supposed to happen. I set debug to verbose.

The following is the last portion of the debug output after I disabled the cell phone hotspot. It only ended when I re-enabled the hotspot. The onDisconnected event (not shown here) fired when the hotspot was disabled, unlike when debug was set to none.

Which version of ESP32 core are you using?

Hi @lilbuzz

When WiFi.setSleep(false); reconnect seems to never happen. Removing it or setting it to WiFi.setSleep(true); worked. Seems bit strange.

#define BAUD_RATE         115200

#define WIFI_SSID         "xxx"    
#define WIFI_PASS         "xx"

#include <WiFi.h>
  
// setup function for WiFi connection
void setupWiFi() {
  Serial.printf("\r\n[Wifi]: Connecting");

  //WiFi.setSleep(WIFI_PS_NONE); 
   WiFi.setSleep(false);
   WiFi.setAutoConnect(true);
   WiFi.setAutoReconnect(true);
 
  WiFi.begin(WIFI_SSID, WIFI_PASS); 

  while (WiFi.status() != WL_CONNECTED) {
    Serial.printf(".");
    delay(250);
  }
  Serial.printf("connected!\r\n[WiFi]: IP-Address is %s\r\n", WiFi.localIP().toString().c_str());
  
}
 

// main setup function
void setup() {
  //esp_log_level_set("*", ESP_LOG_VERBOSE); 
  Serial.begin(BAUD_RATE); Serial.printf("\r\n\r\n");
  setupWiFi(); 
}
 
const char* wl_status_to_string(wl_status_t status) {
  switch (status) {
    case WL_NO_SHIELD: return "WL_NO_SHIELD";
    case WL_IDLE_STATUS: return "WL_IDLE_STATUS";
    case WL_NO_SSID_AVAIL: return "WL_NO_SSID_AVAIL";
    case WL_SCAN_COMPLETED: return "WL_SCAN_COMPLETED";
    case WL_CONNECTED: return "WL_CONNECTED";
    case WL_CONNECT_FAILED: return "WL_CONNECT_FAILED";
    case WL_CONNECTION_LOST: return "WL_CONNECTION_LOST";
    case WL_DISCONNECTED: return "WL_DISCONNECTED";
  }

  return "NO";
}

 String lastStatus = "";

void loop() {   
    String currentStatus =  wl_status_to_string(WiFi.status());

    if(currentStatus != lastStatus) {
      Serial.print("currentStatus:");
      Serial.println(currentStatus);

      Serial.print("lastStatus:");
      Serial.println(lastStatus);

      lastStatus = currentStatus;
    }
}

I am using the latest esp core. I always keep my libraries up to date.

[lilbuzz]

Are you asking me to change the setting of the setSleep() method?

[lilbuzz]

I commented the line containing the setSleep call, but that did not change the behavior.

[lilbuzz]

Notes on the disconnected behavior:
With debug set to verbose, the onDisconnected event is inconsistent. Sometimes it fires when the hotspot is disabled, and sometimes it does not fire until the hotspot is re-enabled, followed by the onConnected event.
When debug is set to none, the onDisconnected event never fires when the hotspot is disabled, but always fires when the hotspot is re-enabled, followed by the onConnected event.

[kakopappa]

Yes. i noticed the unpredictable behavior.

a similar issue has been fixed in 3.0.0-alpha2 may be you can give it a try

espressif/arduino-esp32@7c79cdd

[lilbuzz]

An alpha version of the esp32 core? I am not sure that I want to try that. I don't want to risk bricking my esp32.

[kakopappa]

Hi,

did some testing with @sivar2311

1. When I tested the sketch on my IPhone, never connected back to IPhone AP. Looks like bug in Arduino Core when WiFi.setSleep(false) won't reconnect to WiFi AP espressif/arduino-esp32#8877
2. When I tested it on my WiFi Repeter, sometimes it failed to connect back to AP.
3. For Boris, tested it on his WiFi Repeter, it always connects back

I think it's better to use WiFi.status() != WL_CONNECTED in the loop() to detect disconnections rather than depending on callback.

Check this:

[lilbuzz]

I will change my code to use the WiFi.status() method.
Thanks for the link - I will check that out as well.
