BME680 failure

[Idahowalker]

I been running a BME 680 since Feb 11th 2020.

This AM the ESP32 running the 680 shows this error,

Backtrace: 0x4000c2e4:0x3ffe3b80 0x400d2331:0x3ffe3b90 0x400d10bb:0x3ffe3bb0 0x400d6eaf:0x3ffe3bd0 0x400820f9:0x3ffe3bf0 0x400822d5:0x3ffe3c20 0x4007906f:0x3ffe3c40 0x400790d5:0x3ffe3c70 0x400790e0:0x3ffe3ca0 0x400792a9:0x3ffe3cc0 0x400806ea:0x3ffe3df0 0x40007c31:0x3ffe3eb0 0x4000073d:0x3ffe3f20

Which translates to this error:

The error is happening with this line of code: Adafruit_BME680 bme( GPIO_NUM_5 ); // hardware SPI

If I comment out that line of code then I do not get an error.

[Idahowalker]

I have also tried to use: SPIClass SPI1( HSPI ); Adafruit_BME680 bme( GPIO_NUM_5, SPI1 ); // hardware SPI, kept getting an error about SPI1 is an int and not a SPI object.

@Idahowalker Hey, thanks for opening this issue. What version of the library are you using?

[evaherrada]

1.1.0 could be broken, so do you think you could test it with 1.0.8 and let me know if you get the same issue? Thanks!

[Idahowalker]

Switched to using version 1.0.8 I get:

@Idahowalker Well, it definitely makes me feel better that this was an issue before 1.1.0, but it's still not good that's happening. I don't know C++, but I'll try to have someone who does help you with this.

[Idahowalker]

As a note, I tried using https://github.com/SV-Zanshin/BME680/blob/master/examples/SPIDemo/SPIDemo.ino, that library works.

[evaherrada]

@Idahowalker You mean that the example you linked works with SV-Zanshin's library, right?

Also, I don't think you're meaning to close the issue every time. If you press the green 'comment' button instead of the 'close and comment' button, it won't close the issue

[evaherrada]

Also, if you don't mind, I've got one more thing I'd like you to try. Do you think you could give it a go with 1.0.7? It's possible that the regression happened in 1.0.8 so I'd like to see if that might fix it

[Idahowalker]

I am back to using 1.0.7, which works.

I am not sure why 1.0.8 and above update the oled display driver and mess with core0.

[evaherrada]

Awesome. That's actually great news since we now know the regression happened in-between 1.0.7 and 1.0.8 which significantly narrows our search for the issue.

Thanks

[evaherrada]

Here are the changes from 1.0.7 to 1.0.8. It's a lot, but I'll try to take a look through and see if I can find anything that may have caused the issue.

https://github.com/adafruit/Adafruit_BME680/compare/1.0.7...1.0.8

[sblantipodi]

I chime in. If you see the difference between the 1.0.7 and 1.1.0 code constructor changed without any breaking changes notice in the changelog.

constructor changed from

/**************************************************************************/
Adafruit_BME680::Adafruit_BME680(int8_t cspin)
  : _cs(cspin)
  , _meas_end(0)
{
  _BME680_SoftwareSPI_MOSI = -1;
  _BME680_SoftwareSPI_MISO = -1;
  _BME680_SoftwareSPI_SCK = -1;
  _filterEnabled = _tempEnabled = _humEnabled = _presEnabled = _gasEnabled = false;
}

to this:

/*!
 *  @brief  Instantiates sensor with i2c.
 *  @param  *theWire
 *          optional Wire object
 */
Adafruit_BME680::Adafruit_BME680(TwoWire *theWire)
    : _cs(-1), _meas_start(0), _meas_period(0) {
  _wire = theWire;
  _BME680_SoftwareSPI_MOSI = -1;
  _BME680_SoftwareSPI_MISO = -1;
  _BME680_SoftwareSPI_SCK = -1;
  _filterEnabled = _tempEnabled = _humEnabled = _presEnabled = _gasEnabled =
      false;
}

this can be the problem here imho.

Correct, the SV-Zanshin's library worked, I wanted to prove that the BME 680 I have is still working. Thanks for the tip on closing.

I am currently using the Adafruit version 1.0.7 BME680 library which is working.

[evaherrada]

That's good to know. I'll have someone more familiar with this library and C++ in general come take a look at this and hopefully we'll be able to get the next version fully functional

[siddacious]

@Idahowalker @dherrada after some unrelated issues I was able to reproduce this. I'll dig in and see what's up.

@Idahowalker hi please try the latest commit here (you'll have to uninstall and then manually install this library) https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use

@Idahowalker hi please try the latest commit here (you'll have to uninstall and then manually install this library) https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use

The link provided is a bit vague as to the location of the library you want me to test. Could you supply a link that gives a bit more directionalality as to the location of the library you want me to test?

[ladyada]

this library https://github.com/adafruit/Adafruit_BME680/archive/master.zip

[Idahowalker]

I installed the new library from the zip. I uploaded the code to a ESP32 that does not have a BME680 attached. The new library did not fail on Adafruit_BME680 bme( GPIO_NUM_5 );. Yea.

Right now and for the rest of the day, its raining outside. The BME680 is physically attached to a weather station that's outside. I do not want to, at this time, open the weather station and load the new library to the weather station. When the rain stops, supposed to be tonight, I will bring the weather station inside, upload the new library, and test. The good news is that the library did not, at instantiation, crash the ESP32. So bear with me, for another day-ish, for when the rain stops, to get the results of a full operational test.

[ladyada]

ok!

[Idahowalker]

I have uploaded the test library, which shows up as 1.1.0. I did not experience any instantiation errors and is producing a result set. I will let the device run, inside, for several hours, then move the device outside if I do not get any BME680 library issues. I really do not expect for their to be issues at this point.

[Idahowalker]

I have closed and sealed the weather station electronics and place the weather station outside to assume normal operations. I do no foresee any more issues but if I do.

Oh, Thanks.

[ladyada]

great!
