BME280 > SignalK no data/gauges

[Jay_cd33]

 
So I figured out the problem with not getting BME280 sensor data into SignalK described in my previous posts.

It turns out Adafruit has updated their BME280 python library used in the openplotter i2c app to read sensor data. So new installs download the updated library which breaks the openplotte i2c read app.  The openplotterI2cRead app runs as a service, reads the sensor data and sends it to signalk.  The problem is that the library import in openplotterI2cRead.py is not compatible with the new library.   So the openplotter i2c app sets up the bme280 sensor correctly and configures signalk with a good connection but no data is sent to that connection by the openplotterI2cRead app.

So Sailoog needs to correct the BME280 library import call in a future release.   For those that are willing to hack the changes necessary to make it work here is what I did...

In the directory;
/usr/lib/python3/dist-packages/openplotterI2c
The file openplotterI2cRead.py needs to be edited. (sudo needed to edit file),

Change line 44 (in the BME280 section)
from:        
        import adafruit_bme280

to:
        from adafruit_bme280 import basic as adafruit_bme280

(be aware the from is preceeded by 2 tabs not spaces).

After saving these changes, either restart the openplotter-i2c-read.service or reboot.

That fixed the problem for me.   I hope this helps others.  
I'm not a coder so Sailoog will probably have a proper fix in a future release.

Thank you, Thank you. That worked! I submitted PR#6 (Pull Request #6 for openplotter-i2c), just needs to be approved then merged. I would encourage you to do the same in the future when you solve a problem, it helps everyone else down the line! When I was experimenting with the TTGO LoRa32 OLED Board version 1, it was not supported for Arduino development so I sent email to LilyGo to request they fix it. Well, it never happened. So I researched variants in Arduino and how to do a PullRequest on GitHub and did my own, now other people can use that board. This is a very helpful article on how to do pull requests: How to create a pull request in GitHub.
Also, the way you solved this problem and looking at the time you posted the fix, you are a coder!

Thank you for the kind words and for doing the pull request.   You are exactly correct about me not knowing how to do a pull request on GitHub.  Thanks for the "How to" link.
