Server connection troubles

[khorner116]

I am having an intermittent problem with my IOT setup. It has been running and upgraded at various times over the past two years. Recently, it has had trouble connecting to the Sinric server. On maybe 1 in 5 resets it hangs.

The code has defined the SinricPro.onConnected([]() function within a startup routine...

SinricPro.onConnected([](){ if(DisplayOnConsole)Serial.printf("Connected to SinricPro\r\n"); tft_scroll("..SinricPro connected",3); Sinric_connected=true;}); // Set this flag to let the rest of the code know

And once it executes the statement it flows into a waiting loop. SinricPro.begin(APP_KEY, APP_SECRET); delay(1000);
FailTime=millis(); while (!Sinric_connected) { // Hold in this loop until if(DisplayOnConsole)Serial.printf("."); // we reconnect or we let the watch timerWrite(timer1, 0); // dog timer trip after a 5 min delay. SinricPro.handle(); delay(250); if((millis()- FailTime) >300000) while(1); // Watch dog times out here } }

As shown above, the code following the Begin statement loops and calls the handler till the Sinric_connected variable becomes true.

This works almost all the time, but occasionally it will hang forever. As shown above, I've recently implemented a watchdog timer routine to let it hang for 5 minutes and then reboot the ESP32, But sometimes even a complete restart doesn't clear the issue. After a 1/2 hour or so it seems to go away. I'm looking for insight into the issue. Should I be doing some sort of formal disconnect (like I do for the WIFI startup). Or what? Ideas please.

You can retrieve the connection status directly with SinricPro.isConnected().

Remove the delay(250) statement in your loop. delay() blocks the entire sketch and thus SinricPro.handle() (which establishes the connection). Please use a non-blocking code (like Blink without Delay) for the output of the dots.

But I suspect the problem is more likely to be on the WiFi side. Please test this first via a mobile hotspot using your smartphone. If there are no problems, please restart your WiFi router and test the connection again via your WiFi router.

Thanks. I've added the SinricPro.isConnected() call and removed the delay stmt. I also added a test earlier to only call Sinric Start or Restart if we have a good wifi link and the Sinric server is disconnected. We will do some more testing to see what's what.

Just another question... is there a Sinric Disconnect call similar to WiFi.disconnect(true) that would effectively force a wipe of any parameters? Create clean slate so to speak.

SinricPro.begin() works differently than WiFi.begin()! SinricPro.begin() does not save any credentials - this is up to the user.

SinricPro.stop() disconnects the underlying websocket connection to the SinricPro server. SinricPro.handle() will reconnect automatically if ithe (websocket) connection was disconnected - except SinricPro.stop() was called before.
