Photon 2 frequently goes offline and eventually locks up

jstobaugh · August 31, 2023, 11:29am

First project with Photon 2 and I am upgrading an existing project from an Argon to the Photon 2. The Argon has worked for over a year with no issues. Both the Argon and Photons are using 5.4.1. I have taken the existing code and only replaced the I/O portion of the code to update for the different pinouts. The new circuit board the Photon 2 is plugged into has the same components as the Argon. All I/O connections are disconnected to the circuit board except a 20x4 I2C liquid crystal display and any other components on the board a passive. I do have the Blynk library installed also but have disabled the portion of the code allowing it to connect to the cloud for troubleshooting.
My problem is randomly the Photon 2 will go offline just briefly and come back online. This is random and can happen from a few to several times an hour. At some point from 1 to several hours the Photon 2 will stop responding and the LED will be solid blue or out completely. I have two separate circuit boards with Photon 2's running the same code and both act the same and stop responding. One is USB powered by my computer so I can monitor the logs and the other uses a 5 volt power supply.
Monitoring the free memory shows no memory leak. The code shows 60k being used on the Argon and 120k being used when on the Photon 2 so I am assuming more overhead needed for the Photon 2? Below is the log file showing several times going offline and the last entry when the device failed. I could use any help to determine where to go to next in troubleshooting though I believe it should be working fine since it has worked fine on the Argon.

One thing you could try is to borrow a Wi-Fi antenna from an Argon and connect it to the Photon 2. Enable it using

BLE.selectAntenna(BleAntennaType::EXTERNAL);

This would help isolate whether the disconnects are occurring because of Wi-Fi signal, or some other cause.

jstobaugh · August 31, 2023, 2:12pm

I connected them to an Argon antenna and set external. I am still getting it going offline. I do have several Photons and two Argons on the same wifi with no issues. The Photon 2's are only about 20 feet from the router. Below is the log in case it is different output.

gusgonnet · August 31, 2023, 3:01pm

Hi, are you using 5GHz or 2.4GHz WiFi on the Photon2?
I think 5GHz signals are more likely to be weakened or blocked by obstacles like walls, floors, and ceilings than 2.4GHz.

jstobaugh · August 31, 2023, 3:26pm

I am using 2.4 Ghz for that reason and I am in a rural area and no other wifi signals in the area.

marekparticle · September 13, 2023, 12:19am

@jstobaugh is this issue still live?

jstobaugh · September 13, 2023, 12:46am

Yes it is still alive. I am still isolating to the part of the code that fails and am very close. I didn't want to post anything until I was certain it wasn't something in my code that may not be proper.
I have had many issues isolating it because it will at some point fail on OTA programming and Workbench didn't report it had failed. I had to find out by looking at the web console. Once a Photon 2 fails an OTA update the only way to get it back to working is Device Doctor. I have also had one Photon 2 partially brick while in the middle of a local flash from Workbench. I can't recover it with Device Doctor or Device Restore but it still connects to the cloud.
Hopefully tomorrow I will have determined if it is a problem I created or a possible bug.

jstobaugh · September 13, 2023, 1:18pm

@marekparticle Here is the code I have isolated that is causing the problems. The first issue is the device will momentarily go offline and then back online. The second issue is after a period of time the Photon 2 will freeze. I am using 5.5.0. I use Workbench and compile OTA and then I have been flashing by USB. I have removed a large portion of the programming so this function isn't doing anything because counter was manipulated by removed code.

marekparticle · September 13, 2023, 2:05pm

Hm, this is still a little on the complex side for us to work through. Do you mind cleaning this up just a bit more until it's <100 lines and super easy to follow? Have you identified where the hang occurs in that function?

@rickkas7 any immediate concerns here?

jstobaugh · September 13, 2023, 5:37pm

I will continue to work thru it. I don't know where the hang occurs.

peekay123 · September 13, 2023, 6:33pm

@jstobaugh, just a few comments.

The logic is odd. First, since you are adding to the value of setswStage1Counter it will never be less than zero. I believe the rule should be:

if (setswStage1Counter > 25)
  setswStage1Counter = 25;

Similarly,

Can be changed to:

 if (setswStage1Counter < 1)
  setswStage1Counter = 1;

Once thing I noticed is that you call EEPROM.get(16, setramStage1Counter); every time loop runs! The EEPOM on the Photon 2 is actually implemented as a LittleFS file. From what I see, loop() will run every 1ms! I'm not sure if this could be part of the offline problem.

You already have the EEPROM value loaded in the global setramStage1Counter variable so simply maintain the value there and store it back to EEPROM only when it changes, (setramStage1Counter != setswStage1Counter) in your case.

jstobaugh · September 13, 2023, 9:41pm

Thanks for the response @peekay123. The counter is a hourly timer controlled in tenths of an hour between 0 and 25 and is programmed with the time using two switches. The valueup switch increases the time by tenths and the valuedwn switch decreases the value by tenths. The code to do that is a separate function that has been removed. The hourly counter value is limited to be between 0 and 25. The EEPROM issue I hadn't thought about when creating it and will change it to your example and see if that fixes the problem. I will let you know if it does fix it.

jstobaugh · September 14, 2023, 7:44pm

Moving the Get EEPROM to after a change is detected appears to have fixed the wifi going offline. I need to monitor for a day to see if the Photon 2 doesn't crash anymore. Thanks very much for the help. Below is the change I had to do so the EEPROM wasn't constantly loaded.

 if ((setramStage1Counter != setswStage1Counter) && (isnan(setramStage1Counter) == false))
  {
    EEPROM.put(16, setswStage1Counter);
    EEPROM.get(16, setramStage1Counter);
  }

peekay123 · September 15, 2023, 6:07pm

@jstobaugh, I'm not sure I understand why you get setramStage1Counter from EEPROM when you already have it loaded for your if() statement.

jstobaugh · September 15, 2023, 8:07pm

Maybe there is a different way that I am not doing but without the get statement the EEPROM is never updated when I change the setramStage1Counter manually with the switch. Also the Photon 2 is working properly now with no wifi offline or locking up.

peekay123 · September 16, 2023, 1:26am

This doesn't quite make sense to me. I would need to see your code to understand what may be causing what you see.

jstobaugh · September 16, 2023, 12:24pm

@peekay123 below is the code related to what I am doing with the EEPROM. I use the Blynk app to load the value into the counter and then once started the counter is decremented every .1 hour. The Blynk app starts the counter setting the (Stage1Run == true).

float setramStage1Counter; //EEPROM location
float setswStage1Counter; 
void setup()
{
EEPROM.get(16, setramStage1Counter);
setswStage1Counter = setramStage1Counter;
}

void loop()
{
CounterStage1timer();
CounterStage1swset();
}
void CounterStage1swset()
{
  if ((setramStage1Counter != setswStage1Counter) && (isnan(setramStage1Counter) == false))
  {
    EEPROM.put(16, setswStage1Counter);
    EEPROM.get(16, setramStage1Counter);
  }
}
 
void CounterStage1timer()//decriment counter every .1 hour
{
  if (Stage1Run == true)
  {
    if (setswStage1Counter <= 0)
    {
      Stage2Run = true;
      Stage1Run = false;
      SmokeEn = false;
      Particle.publish("SmokerJim", "Stage 2 started", PRIVATE);
    }
    unsigned long now1 = millis();
    if (now1 - lastStage1timeCheck >= 360000) 
    {
      setswStage1Counter = setswStage1Counter - .1;
      lastStage1timeCheck = millis();
    }
  }
}
BLYNK_WRITE(V24)////Use Blynk app to load value into setswStage1Counter
{
  setswStage1Counter = param.asDouble(); // assigning incoming value from pin V1 to a variable
}
