Hi guys. I am a beginner and trying to add support for more than one BMP280 barometer. I set baro_max_instances to 4, but among the I2C devices, only one BMP280 barometer out of 3 connected by me is displayed. The rest simply do not get their ID address, all 3 hang on the same ID.Please tell me how I can carry out my plan? I will be grateful for any help!
Are the baro ICs configured to use different IDs?
From the BMP280 datasheet:
So, you’ll only be able to connect two BMP280s at a time, since there are only two available I2C addresses.
