Drivers for BME680

[Ulf Hedblom]

Hi

I would like to connect a BME680 sensor to the nRF9160DK board. The driver for this sensor isn't included included in the v1.14.99-ncs2 branch but it shows up in the v1.14.99-ncs3 snapshots. Do you know if/when the ncs3 will be released and if it will include this driver or am I confused and asking this question in the wrong place?

Hi!

The driver for the BME680 sensor was just added to the master branch two weeks ago. So if you run 'git checkout master' it can be found in \ncs\zephyr\drivers\sensor\bme680. You can find it here as well. 

Best regards,

Heidi

Hello Heidi

I followed same(above) code for nRF52840, but on my DK with BME680 temperature is working fine, but humidity, pressure and gas are not working, every time same readings are observed, actually those are wrong values. From sensor raw data is changing every time, my calibration and calculation formulas also right, but I am not getting correct reading for humidity, pressure and gas. What I should do, can you please help me?

What kind of readings do you get for humidity and pressure? Are they just absurd values? I have used the nRF52 aswell as the nRF91 with the BME680 sensor and if I manage to get it to work I always got what seemed to be correct values for temperature, pressure and humidity and if I didn't get it to work I ended up with calculations from a 'zero-value' which out of reasonable range.
