Saw one other post without resolution on this, but I’m seeing too high of expected readings from my BerryGPS-IMUv3, specifically temperature and pressure. Temperature seems to be fairly consistent at ~85 F, when at the moment it should be around 65-70 at most.
Pressure is also reading very high at ~1017 hPa, which puts me around 117 ft below sea level. I live just about at sea level, roughly 6 ft above.
While I’m not using the device for mission critical reasons, it also wasn’t particularly cheap – just wondering if there’s any basic troubleshooting I could do or if there are known calibration offsets to use.
For what it’s worth, this is attached to a Raspberry Pi Zero W, and I’m using the following settings:
CTRL_MEAS: 0x2F (Temperature OS x1, Pressure OS x4, Normal Mode)
CONFIG: 0xB0 (Standby 1000ms, Filter 16)

And is it the BMP180 or BMP280?
