Getting Infinite loop with compiled code...can you pls help? #529

Open satssehgal opened 6 years ago

satssehgal commented 6 years ago

Hi Guys, I’m new here so please dont shoot my head off if I’ve accidentally broken a rule while posting. So i’m new to the homie framework, i’ve successfully compiled code for my door sensor alone but now i want to use additional sensors for my wemos d1 mini. There are obviously a bunch of smart folks on this site and I wanted to seek some assistance.

I compiled the code but its going into an iterative loop in the serial monitor. can someone please spot where i may have gone wrong? Much appreciated in advance

`

#include <Homie.h>
#include <ArduinoJson.h>

const int PIN_DOOR = D1;
const int PIN_WATER = D3;

bool sleepFlag = false;

Bounce debouncer = Bounce(); // Bounce is     built into Homie, so you can use it without including it first
int lastDoorValue = -1;
int lastWaterValue = -1;

HomieNode doorNode("door", "door");
HomieNode waterNode("water", "water");

void loopHandler() {
  int doorValue = debouncer.read();
  int waterValue = debouncer.read();

  if (doorValue != lastDoorValue) {
      Homie.getLogger() << "Door is now " << (doorValue ? "open" : "closed") << endl;

    doorNode.setProperty("open").send(doorValue ? "true" : "false");
     lastDoorValue = doorValue;
  }
   if (waterValue != lastWaterValue) {
     Homie.getLogger() << "Water sensor state is " << (waterValue ? "Leak Detected" : "clear") << endl;

     waterNode.setProperty("clear").send(waterValue ? "true" : "false");
 lastWaterValue = waterValue;
  }
}

void onHomieEvent(const HomieEvent& event) {
   switch(event.type) {
     case HomieEventType::MQTT_READY:
       Homie.getLogger() << "MQTT connected, preparing for deep sleep..." << endl;
      Homie.prepareToSleep();
      break;
     case HomieEventType::READY_TO_SLEEP:
      Homie.getLogger() << "Ready to sleep" << endl;
      ESP.deepSleep(0);
      break;
  }
}

void setup() {
  Serial.begin(115200);
  Serial << endl << endl;
  Homie.disableResetTrigger();  // we do not want to trigger config mode by sensor input
  pinMode(PIN_DOOR, INPUT);
 pinMode(PIN_WATER, INPUT);
  digitalWrite(PIN_DOOR, HIGH);
  digitalWrite(PIN_WATER, HIGH);
  debouncer.attach(PIN_DOOR);
  debouncer.attach(PIN_WATER);
  debouncer.interval(50);

  Homie_setFirmware("my-sensors", "1.0.0");
  Homie.setLoopFunction(loopHandler);
  Homie.onEvent(onHomieEvent);

  doorNode.advertise("open");
  waterNode.advertise("clear");

 Homie.setup();
}

 void loop() {

  Homie.loop();
  debouncer.update();

}

I haven't tested the code yet, but by looking at it, it looks like your doing to much to soon and not enough time given to the IP stack to actually send all the packets, not sure about this though.

Will test the code later.

Would be nice though if you could decode your stack trace. (Make sure the stack trace is from the exact same build)

satssehgal commented 6 years ago

@timpur thanks Tim. So maybe this can help zero in on the issue. when i comment out Homie.onEvent(onHomieEvent); it compiles and works fine, it just doesn't enter deep sleep. Also i changed ESP.deepsleep() to Homie.doDeepSleep() and the loop went away but now it just crashes after a few min. I just dont know what im doing wrong there.

Sorry what do you mean decide stack trace?

luebbe commented 6 years ago

@satssehgal Thanks for opening a new ticket. You still need some practice how to format source code in a ticket though. ;) Using preview and the github markdown cheat-sheet might get you up and running.

I think @timpur wanted to write "decode" stack trace. For instance with one of these tools: https://github.com/me-no-dev/EspExceptionDecoder https://github.com/littleyoda/EspStackTraceDecoder

Does you code run, when you leave out the sleep stuff?

luebbe commented 6 years ago

Can you really attach two pins to one debouncer? I haven't checked, but I don't think so. What do you think will happen when your ESP is sleeping and the door opens/closes or your water pin changes state?

satssehgal commented 6 years ago

You’re totally right Sorry I should have stated that I created another denounce. I’ll post the updated code soon when I’m home. That was the other change I made

@luebbe thanks for the markdown cheatsheet idea. Didn't know it existed. How did i do? :) So you're right i did add a debounce.

@timpur @luebbe So this code compiles and works only if i take out the deep sleep function. If i want to run this on a battery say using an ESP-01, it wont last long. 

#include <Homie.h>
#include <ArduinoJson.h>

const int PIN_DOOR = D1;
const int PIN_WATER = D2;

bool sleepFlag = false;

Bounce debouncer_door = Bounce(); // Bounce is built into Homie, so you can use it without including it first
Bounce debouncer_water = Bounce(); // Bounce is built into Homie, so you can use it without including it first

int lastDoorValue = -1;
int lastWaterValue = -1;

HomieNode doorNode("door", "door");
HomieNode waterNode("water", "water");

void loopHandler() {
  int doorValue = debouncer_door.read();
  int waterValue = debouncer_water.read();

  if (doorValue != lastDoorValue) {
     Homie.getLogger() << "Door is now " << (doorValue ? "open" : "closed") << endl;

     doorNode.setProperty("open").send(doorValue ? "true" : "false");
     lastDoorValue = doorValue;
  }
  if (waterValue != lastWaterValue) {
     Homie.getLogger() << "Water sensor state is " << (waterValue ? "Leak Detected" : "clear") << 
endl;

 waterNode.setProperty("clear").send(waterValue ? "true" : "false");
 lastWaterValue = waterValue;
  }
}

void onHomieEvent(const HomieEvent& event) {
  switch(event.type) {
    case HomieEventType::MQTT_READY:
      Homie.getLogger() << "MQTT connected, preparing for deep sleep..." << endl;
      Homie.prepareToSleep();
      break;
    case HomieEventType::READY_TO_SLEEP:
      Homie.getLogger() << "Ready to sleep" << endl;
      Homie.doDeepSleep();
      break;
  }
}

void setup() {
  Serial.begin(115200);
  Serial << endl << endl;
  Homie.disableResetTrigger();  
  pinMode(PIN_DOOR, INPUT);
  pinMode(PIN_WATER, INPUT);
  digitalWrite(PIN_DOOR, HIGH);
  digitalWrite(PIN_WATER, HIGH);
  debouncer_door.attach(PIN_DOOR);
  debouncer_water.attach(PIN_WATER);
  debouncer_door.interval(50);
  debouncer_water.interval(50);
  Homie_setFirmware("my-sensors", "1.0.0");
  Homie.setLoopFunction(loopHandler);
  doorNode.advertise("open");
  waterNode.advertise("clear");
  //Homie.onEvent(onHomieEvent);
  Homie.setup();
}

void loop() {

  Homie.loop();
  debouncer_door.update();
  debouncer_water.update();
}

Found updating the AsyncMqttClient lib fixed this for me, pio lib install AsyncMqttClient

n8twj commented 6 years ago

Also, make sure GPIO16 is connected to RESET, to be woken up from deep sleep.

satssehgal commented 6 years ago

@n8wj Thanks I actually didn’t do that. Would you suggest I solder a wire between DO and RST on the D1 mini or use a resistor?

For the ESP-01 can someone correct me if I’m wrong in saying that gpio is that really tiny pin just above the ground pin? Has anybody been able to solder that?

@timpur I have version 0.8.2 installed so it looks like it’s updated. I still have the issue but will try the reset to D0 button connected

@n8twj @timpur so tying D0 and RST didnt fix the situation. In node red I have the correct status reporting but it continues to report every second. In serial monitor Arduino IDE, same crazy loop.

Any other suggestiosn?

timpur commented 6 years ago

@satssehgal Try the latest everything? 2.4.1 Arduino core also ?

Your code works for me now :)

satssehgal commented 6 years ago

@timpur yeah I’m running 2.4.1 Still same issue

My board is wires as follows. Maybe it’s my config

I’ll just put the config for the door sensors, water sensor is the same except different pin

D0 —-> RST Door sensor lead 1 —-> 3V3 Door sensor lead 2 ——> D1 D1 —-> 4.7k resistor —-> Ground ( I’ve tried this with a straight wire and resistors from 2.2k to 10k)

I’m sure it’s something silly I’ve missed

@timpur the code compiles fine but when I put it on the D1 mini it goes through that crazy loop. :(

BTW here are my stacktrace results...again i have the latest libs and arduino core....

That's the error I got, but updated my mqtt lib and it went away ...

satssehgal commented 6 years ago

@timpur yeah it’s really odd I can’t seem to get it to work. My mqtt lib is updated. For me I’m not sure that is the issue because if I remove the deepsleep function it works without issue

There are quite a lot of matches when you google for "Exception (28)" https://arduino-esp8266.readthedocs.io/en/latest/exception_causes.html

@satssehgal did you delete all previous version of your libs inside the library path? I sometimes had trouble when an old version was found alongside a new library. In PlatformIO I delete the entire lib folder every now and then and let it rebuild, when I get spurious errors.

satssehgal commented 6 years ago

@luebbe thanks for the suggestion. I just did that and still didnt work.

I had exception 28 - A load referenced a page mapped with an attribute that does not permit loads. Dont even know what means :)

luebbe commented 6 years ago

I think it means that a pointer is pointing to nirvana an something is trying to read/write from that location.

satssehgal commented 6 years ago

@luebbe i'll have to research the error 28...i'm just baffled how some of you got it to work while mine is throwing off this error still. I just tried to compile it with a new D1 mini and same issue.

timpur commented 6 years ago

@satssehgal , can you give us a break down of your environment (Platform IO?, arduino core version? ...ect), board your use and flash size ... everything ?

Have you set the right flash size, the right flash mode ect?

satssehgal commented 6 years ago

@timpur

Here are the details:

Board : Wemo D1 mini Env: Arduino Core 2.41 Tool: Arduino IDE Flash size: 4M (1M SPIFFS) Debug Port: Disabled Debug Level: None IwIP Variant: v2 Lower Memory CPU Frequency: 80 MHz Upload Speed: 115200 Erase Flash: Only Sketch Port: Port on Comp Programmer: AVRISP mkill

Anything else?

@satssehgal , thanks. Ive clean my libs in arduino and started from scratch with latest libs of everything needed for homie. I now have your issue again so ill solve this once and for all :) might take me a bit though ....

satssehgal commented 6 years ago

@timpur No problem I appreciate your help. Thanks :)

Anybody make any headway? So it looks like it breaks even if i comment out deepsleep. Soon as it breaks from the case statement it breaks no matter what is in the case statement

timpur commented 6 years ago

Thanks for sharing that, im going to look at it over the weekend, sorry bussy week ...

satssehgal commented 6 years ago

No problem. I’ve been racking my brain with this one for a while. Thanks for your help

satssehgal commented 6 years ago

any luck on this one? ive been tinkering all week and cant get this deep sleep to work

jmozmoz commented 6 years ago

I also got this problem. I worked around it, by disabling all mqtt publishing and wait for a certain amount of time before issuing the command to go to deep sleep. Have a look at the source code: https://github.com/jmozmoz/yagds/blob/master/uploadSensorData/src/main.cpp

Actually I do not call Homie.loop() anymore during waiting to go to deep sleep.

I experimented a lot and this is my current solution which seems to work.

satssehgal commented 6 years ago

Thanks and how is battery life for you on this?

gaelgrasset commented 6 years ago

I had the exact same issue last week... Oddly it was only when compiled with Arduino IDE. Debug stack pointed out that Async MQTT was the source of the problem, but I was on the last version of all libs. I found 2 different workarounds:

jmozmoz commented 6 years ago

I am using PlatformIO and see this problem. Here my platformio.ini:

[env:esp01_1m]
platform = espressif8266
board = esp01_1m
framework = arduino
build_flags = -DASYNC_TCP_SSL_ENABLED=1 -Wl,-Teagle.flash.1m64.ld
lib_deps =
  https://github.com/marvinroger/homie-esp8266.git#v2.1
  simpleTimer
  jled
satssehgal commented 6 years ago

@gaelgrasset I tried both methods and neither seem to work. I’ve just been using an outlet over batteries out of sheer frustration

x821938 commented 6 years ago

I have also been fighting with this problem. My solution was to revert to 0.8.1 of AsyncMqtt: https://github.com/marvinroger/async-mqtt-client/releases/tag/v0.8.1 (remember to build clean and rebuild everything)

MoJo2600 commented 5 years ago

I ran in the exact same problem. Reverting AsyncMqtt to 0.8.1 resolved the error for me.

boneskull commented 5 years ago

FWIW I couldn't figure out how to revert to v0.8.1 using PlatformIO without vendoring Homie and manually patching its library.json. I didn't love that idea, but thankfully it wasn't necessary.

Instead, I used @jmozmoz's strategy above--once I was able to get my head around it--and get consistent deep-sleep without exceptions on a D1 Mini Pro. The trick, as @jmozmoz mentions, is to essentially stop the Homie loop once Homie.prepareSleep() has been called. But once you stop the loop, the READY_TO_SLEEP event either won't emit or the handler won't be invoked (not sure which), so you need to manually invoke deep sleep via a timer (sleepTimeoutId in @jmozmoz's code).

I'm not sure how short that sleep timeout can be, but if it's too short, I imagine Homie wouldn't be fully "ready" for sleep when Homie.deepSleep() is called. I'm also unsure of the necessity of the subsequent ESP.deepSleep() call.

I combined this with the wifi reset strategy mentioned here, because wifi was not reconnecting after wake from deep sleep. To mitigate, it looks like you just need to call WiFiOff(), delay a short period, then call WiFiOn() again at the start of your setup() function.

MoJo2600 commented 5 years ago

Just for the first part on reverting to v0.8.1. The order of the libs matters in the platformio.ini. This is how mine looks like:

lib_deps = 
    AsyncMqttClient@0.8.1,!=0.8.2
    ArduinoJson@5.13.4
    https://github.com/homieiot/homie-esp8266.git#develop-v3
    Timer
