When used separately they all work as expected. When the BNO055 and the SHT31D are used together everything works as expected. When the MiniGPS and the SHT31D are used together everything works as expected.
When the three are used together I can't get past the following error
Code: Select all
ValueError: No I2C device at address: 0x44
Then when take the SHT31D out, and only have the BNO055 and the MiniGPS everything appears to work for a while (5mins). However eventually it will die and I get this error:
Code: Select all
OSError: [Errno 5] Input/Output error
Code: Select all
RuntimeError: No pull up found on SDA or SCL; check your wiring
I don't have a lot of experience with I2C, but I was under the impression there would be no issue daisy chaining the sensors. The STEMMA concept really sells it as "plug-n-play". What am I missing?
