CRC error on response With note.get call

Troubleshooting
1

Newby here, so take that into consideration!

I am still in “sandbox” mode where I am just playing with things to learn how the Notecard ecosystem works. My sandbox program is attempting to create a settings file, store some settings into it, then retrieve it.

The problem I have is that no matter what I have tried, my “note.get” calls have always failed with the “CRC error on response” being written to the [ERROR} output.

Example output is shown below. You will notice that I hub.set commands works fine, then I do a “card.time” request and set the system time of the ESP32. Then I attempt to load the settings file.

If the load of the settings file fails, I assume that the settings file is not correctly setup so I delete the settings file, then I create a default settings file.

I did sometimes get a failure on the delete with an error saying the file was still open. I assumed this was probably a sync problem, so for now I just added some time delays to slow things down.

My “file.delete” works fine.

My “note.add” works fine.

But my “note.get” has never worked.

At one point I connected a USB cable directly to the Notecarrier F and used the Blue.io quickstart terminal emulator to talk direcctly to the Notecard. The “note.get” works fine via this mechanism, but the exact same note.get call from my ESP32 always fails.

Please help.

Below is a log that shows everything from ESP32 boot time, including each request JSON and each response JSON string

Hi @bradleyward,

Which Notecard SDK are you using (e.g. note-arduino or note-python) and what’s the firmware version running on the Notecard? I’m wondering if either (or both) are behind a bit and this issue may be addressed with the latest versions.

Oh, and I am using the Arduino library. I started with the Quickstart code from your website.

I forgot to state the version of the Arduino library: It is 1.5.4

Ok all looks good there. Would you mind posting your full sketch here (or DM me with it) so I can try to reproduce the problem? Also which ESP32 host are you using?

Hi Rob.

I am using an Adafruit ESP32 Feather (Huzzah) processor.

I stripped down my code to a very minimal state that still creates the error. See below.

The “err” code is “crc error (io)”.

Does this mean that an I/O error is occurring in the communincations between the ESP32 and either the Notecard or the Notecarrier? If so, I wondered if one of the sensors OR LCD screen I had hooked to the ESP32 was interfering with that communincation. To test this theory, I unplugged everything from the ESP32. So the only connections the ESP32 has outside of itself is (a) the USB cable plugged in between my Windows 10 PC and the ESP32, and (b) the electrical connections on the bottom of the ESP32 where it plugs into the Notecarrier-F V1.3 board.

Same results: crc error (io)

Here is my example sketch:

//
// Board setting:  Adafruit ESP32 Feather
//
#include <Arduino.h>
#include <TimeLib.h>
#include <Notecard.h>

Notecard notecard;

const char* SETTINGS_FILE_NAME = "settings.db";
const char* SETTINGS_NOTE_NAME = "settings";
const char* PRODUCT_UID = "net.wardsrus.brad:tutorial_project_20240227";

void setup() 
{
   StartSerial();
   SetupNotecard();
   LoadSettings();
}

void loop() 
{
}

void StartSerial()
{
   Serial.begin(115200);
   while (!Serial)
   {
      delay(50);
   }
   Serial.println("Starting NoteGetExample...");
}

void SetupNotecard()
{
   Serial.println("Initializing Notecard...");

   notecard.begin();

   // Tell the Notecard library to use Serial
   // for its debug output.
   // ------------------------------------------
   notecard.setDebugOutputStream(Serial);

   // Now, we'll configure the Notecard. 
   // Using the hub.set request, we associate this Notecard with the 
   // ProductUID of your project and set the Notecard to operate in 
   // continuous mode, which indicates that the device should 
   // immediately make a connection to Notehub and keep it active.
   // --------------------------------------------------------------
   J *req = notecard.newRequest("hub.set");
   JAddStringToObject(req, "product", PRODUCT_UID);
   JAddStringToObject(req, "mode", "continuous");
   PrintRequest(req);
   notecard.sendRequest(req);
   Serial.println("Notecard setup complete.");
}

void PrintRequest(J* request)
{
   Serial.printf("Request object:
%s
",JPrint(request));
}

void PrintResponse(J* response)
{
   Serial.printf("Response object:
%s
",JPrint(response));
}

void LoadSettings()
{
   Serial.printf("Loading %s file...
",SETTINGS_FILE_NAME);

   J *req = notecard.newRequest("note.get");
   if (req != NULL)
   {
      JAddStringToObject(req, "file", SETTINGS_FILE_NAME);
      JAddStringToObject(req, "note", SETTINGS_NOTE_NAME);
      JAddStringToObject(req, "delete", "false");
      PrintRequest(req);
      J* rsp = notecard.requestAndResponse(req);
      PrintResponse(rsp);

      const char* err = JGetString(rsp,"err");

      if (err != NULL && strlen(err) > 0)
      {
	 notecard.deleteResponse(rsp);

	 Serial.println("Settings file could not be loaded from Notecard!");
	 Serial.printf("err = %s
",err);
	 return;
      }

      // The settings file was successfully loaded
      // -----------------------------------------
      Serial.println("Settings file loaded from Notecard.");
      Serial.println("No further code in this example, as the 'note.get' call noow works.");
   }
   else
   {
      Serial.println("notecard.newRequest() returned NULL!");
   }
}

For anyone else getting here with a similar error, check the parameters properly. For example the above is likely caused by

JAddStringToObject(req, "delete", "false")

When it should be

JAddBoolToObject(req, "delete", true);

At time of writing the note arduino code confusingly shows this CRC error instead of the underlying type mismatch error.
