[Question] Server-Side RPC: Receiving Attributes doesn't work

callmereno commented 1 year ago

Generic
Rule Engine(?)

Description Hey guys,

i'm currently working on a server-side rpc application. I basically want to turn on an analog LED via TB. The later works fine (see picture), but when I also want to mirror the analog led on my dashboard, like in this tutorial. Therefore I created a server-side attribute called 'ledStatus' and linked an led indicator to its changes. To send the status i use this TB-function for example:

client.sendAttributeBool("ledStatus", ledStatus);

The problem is that TB doesn't seemt to receive the change of the ledStatus. Am I missing something? Do i maybe have to make a rule chain to process information coming from the device?

I hope my problem is kind of understandable. Suggestions are always appreciated :)

Greetings Reno

Here is the current code. I use the Arduino IDE for coding:

ThingsBoard client(wifiClient);  

// Select AP:
const char* ssid = home;

See #91 for a longer description on the issue you probably have.

The short version is that to receive RPC messages the PayloadSize you are allowed to receive, has to be increased. If that is not done the PubSubClient simply discards the received message.

Therefore replace ThingsBoard client(wifiClient); with ThingsBoardSized<256> client(wifiClient);

callmereno commented 1 year ago

First of all thanks for the quick response @MathewHDYT !

I tried this out, but it sadly didn't make a difference, since i still dont receive client attributes :( I will try to send the attributes as json using the sendAttributeJSON()-function and see if i get results.

Other question: Does it make sense to include the in the sendAttribute...l()-function in the RPC-Response method? Like this for example (<-- is the indicator for the added lines):

RPC_Response processSwitchChange(const RPC_Data& data) {
  Serial.println("Received 'processSwitchChange'-method: ");
  char params[10];
  serializeJson(data, params);
  String _params = params;

  if (_params == "true") {
    Serial.println("SWITCH: ON");
    ledStatus = true;
    client.sendAttributeBool("ledStatus", true); <--
    return RPC_Response("processSwitchChange", "true");

  } else if (_params == "false") {
    Serial.println("SWITCH: OFF");
    ledStatus = false;
    client.sendAttributeBool("ledStatus", false); <--
    return RPC_Response("processSwitchChange", "false");
  }
}

const size_t callbacks_size = 1;
RPC_Callback callbacks[callbacks_size] = {
  { "processSwitchChange", processSwitchChange }
};

bool subscribed = false;  //RPC-Subscribe Status

I think I might know a possible issue, in the comment above you mentioned server side attributes, those can not be read or written to be the client, for the shared attributes they are read only.

So what you are sending with the sendAttributeBool method is a client side attribute, you would need to set the widget to use that attribute instead of the server side one.

And sending the attribute directly in the RPC callback method should work, at least it worked on my device.

That i know :) The tab is empthy though:

MathewHDYT commented 1 year ago

Good to know might It be possible to switch to the newest version 0.8.0 and try it again.

callmereno commented 1 year ago

This could help. Im using version 0.6 becasue i had issues with libraries in 0.7.1. I will keep you postd

callmereno commented 1 year ago

So this is the error i get when i use 0.7.1 :

MathewHDYT commented 1 year ago

I knew 0.7.1 had thoose issues that's why I attempted to fix them, it's interesting tough that it has problems finding the mbedtls/md.h library inv ersion 0.8.0

Might I know what device you are using is it an Arduino Uno perhaps so neither an ESP32 or ESP8266?

callmereno commented 1 year ago

Im using a NodeMCU with a ESP8266(MOD)-Chip

MathewHDYT commented 1 year ago

Could you try to include this library https://github.com/Seeed-Studio/Seeed_Arduino_mbedtls. It should make it possible to use the functionality of mbedtls/md.h on the ESP8266, that is natively supported on ESP32. Sorry for the inconvenience.

callmereno commented 1 year ago

I doesnt find the header file, when i include this line: #include <md.h> I downloaded the asset and added it in the same libraries folder in which the Thingsboard library:

Do i have to specify the path of the header`?

MathewHDYT commented 1 year ago

I think it should be fine to simply just download the library the same way PubSubClient has been downloaded and the include should stay #include <mbedtls/md.h> as far as I know.

callmereno commented 1 year ago

grafik

Same error for some reason..

MathewHDYT commented 1 year ago

What happens if you don't include the library in your main file and then recompile?

callmereno commented 1 year ago

You mean like this #include <library> ?

MathewHDYT commented 1 year ago

Yeah just remove that line and recompile.

callmereno commented 1 year ago

Ah i misread your sentence. This is what happens when i delete the include:

grafik

MathewHDYT commented 1 year ago

Sorry for asking but did you add the library the same way you add the PubSubClient and ArduinoJson library.

callmereno commented 1 year ago

grafik

All good :) Yes i did

MathewHDYT commented 1 year ago

What happens if you download the library over Sketch > Include Library > Manage Libraries and then search for Seeed_Arduino_mbedtls

callmereno commented 1 year ago

grafik

The newest version isnt available in the Arduino IDE. Same goes for ThingsBoard:

grafik

MathewHDYT commented 1 year ago

Can you replace the include statement with this one instead. In the HashGenerator.h file #include <Seeed_mbedtls.h>.

That's the include they had in their example file.

callmereno commented 1 year ago

grafik

It sadly didnt change the outcome.

MathewHDYT commented 1 year ago

Can you remove the old include #include <mbedtls/md.h> because it seems that's the one that is causing problems.

callmereno commented 1 year ago

MathewHDYT commented 1 year ago

Okay perfect those errors are just because the API changed a bit. Just have a look in the examples folder in the ThingsBoard Library more exactly the RPC example and adjust it to be similar to that one.

callmereno commented 1 year ago

Okay i changed the code to this:

void connectRPC() {
  if (!subscribed) {
    Serial.println("Subscribing for RPC...");

    if (!client.RPC_Subscribe(callbacks.cbegin(), callbacks.cend())) {
      Serial.println("Failed to subscribe for RPC");
      return;
    }

    Serial.println("Subscribe done");
    subscribed = true;
  }
}

This is the error i get now:

MathewHDYT commented 1 year ago

Could you also send the code for the callback array itself, because that seems to be the error. I'm assuming it is still a normal c-style array RPC_Callback[], could you make it an std::array or std::vector instead.

callmereno commented 1 year ago

Do you mean in my code or the ThingsBoard.h ? In case you mean the later:

grafik

Should i change it to array?

MathewHDYT commented 1 year ago

No I meant your code sorry for the misunderstanding.

callmereno commented 1 year ago

I mean i never defined an RPC_Callback[]-array if I recall properly. Do you mean this the section where i define the RPC methods?:

RPC_Response processSwitchChange(const RPC_Data& data) {
  Serial.println("Received 'processSwitchChange'-method: ");
  char params[10];
  serializeJson(data, params);
  String _params = params;

  if (_params == "true") {
    Serial.println("SWITCH: ON");
    ledStatus = true;
    return RPC_Response("processSwitchChange", "true");

  } else if (_params == "false") {
    Serial.println("SWITCH: OFF");
    ledStatus = false;    
    //client.sendAttributeBool("ledStatus", false);
    return RPC_Response("processSwitchChange", "false");
  }
}

const size_t callbacks_size = 1;
RPC_Callback callbacks[callbacks_size] = {
  { "processSwitchChange", processSwitchChange }
};

bool subscribed = false;  //RPC-Subscribe Status

MathewHDYT commented 1 year ago

Yeah exactly that's the portion I meant

const size_t callbacks_size = 1;
RPC_Callback callbacks[callbacks_size] = {
  { "processSwitchChange", processSwitchChange }
};

Could you replace it with this

const std::array<RPC_Callback, 2U> callbacks = {
  RPC_Callback{ "example_set_temperature",    processTemperatureChange },
  RPC_Callback{ "example_set_switch",         processSwitchChange }
};

callmereno commented 1 year ago

It compiled!

MathewHDYT commented 1 year ago

Would be nice to know if sending in the RPC callback works now as well like expected.

callmereno commented 1 year ago

Yes, it does:

[TB] Callback on_message from topic: v1/devices/me/rpc/request/30
[TB] received RPC:
[TB] processSwitchChange
[TB] calling RPC:
[TB] processSwitchChange
[TB] params:
[TB] false
Received 'processSwitchChange'-method: 
SWITCH: OFF
[TB] response:
[TB] {"processSwitchChange":"false"}

MathewHDYT commented 1 year ago

Perfect I'll see that the issue we found get's merged into the base library sometime soon, but besides that it seems to work nice :D.

callmereno commented 1 year ago

Great work man!

I still have the issue that the attributes dont arrive :/

MathewHDYT commented 1 year ago

Oh I assumed you mean it works completely XD. Do you get some kind of error message when trying to send the attribute / does the method return true or false?

callmereno commented 1 year ago

No, sorry haha

The thing is dont get any errors.

MathewHDYT commented 1 year ago

Could you add that instead of only the client.sendAttributeBool("ledStatus", false) call.

if (!client.sendAttributeBool("ledStatus", false)) {
    Serial.println("Sending attribute failed :(");
}

callmereno commented 1 year ago

Yes, will try that out:

Seems good what exactly is the console output when you run the script now, does it print "Sending attribute failed :("?

callmereno commented 1 year ago

Check my previous message :)

MathewHDYT commented 1 year ago

You mean the image you posted above, so the script has en exception now?

I'm not sure which message you mean exactly, because the previous comment was your code. Sorry for the confusion.

callmereno commented 1 year ago

Yes I mean the this image:

Yes, will try that out:

MathewHDYT commented 1 year ago

What, but it does work if you don't replace the calls with an if statement? That's really weird...

callmereno commented 1 year ago

Yes, i know... im reverting code back up until this point.

Perfect I'll see that the issue we found get's merged into the base library sometime soon, but besides that it seems to work nice :D.

The code changes arent the reason because I get same error after reverting :/

callmereno commented 1 year ago

What, but it does work if you don't replace the calls with an if statement? That's really weird...

What is an exeception or what could be the acsue of it?

MathewHDYT commented 1 year ago

An exception would be an abnormal behaviour of a program and I'm talking about so abnormal (stackoverflow, memory leak, reading a null pointer, etc.) that your program couldn't fix itself and would crash.

I'm not really sure this is happening tough because it makes no sense, that the few lines you changed would cause a crash.

Are you sure those are the only log messages your received, because normally if the program actually crashes it does show an additional log message why it crashed at least and of course a stack trace that you can see above as well that's the big block of numbers, it simply shows the hexadecimal pointer values of the methods that were called before the crash occured.

You can use a StackDecoder combined with your .elf file to decode them into the actual method names.
