Bme 680 python script not working


#1

Hi there,

I am new to the forum and to the raspberry pi stuff and for my first tryout I bought a bme680 sensor.

So far I couldn’t get any readings from it, althoug I used to code from the github side. Now every time I try to run the python 3 code I get an error.

Estimate indoor air quality

Runs the sensor for a burn-in period, then uses a
combination of relative humidity and gas resistance
to estimate indoor air quality as a percentage.

Press Ctrl+C to exit

Traceback (most recent call last):
File “/home/pi/bme680/examples/indoor-air-quality.py”, line 16, in
sensor = bme680.BME680()
File “build/bdist.linux-armv7l/egg/bme680/init.py”, line 25, in init
self.chip_id = self._get_regs(CHIP_ID_ADDR, 1)
File “build/bdist.linux-armv7l/egg/bme680/init.py”, line 285, in _get_regs
return self._i2c.read_byte_data(self.i2c_addr, register)
IOError: [Errno 121] Remote I/O error

I am not shure if it is from a wrong ic2 because I didn’t solder the pins like in the description which I thought would only be necessary if I use a second one.

I I try to run the second programm I get this error.

Thanks for the help in advance.

BME680 sensor problem solved on this forum, but solution not visible for others?

We got you fixed up in Discord, right? :-) I’ll mark this as solved and close.
