BMP280 strange pressure readings

[mdmobashir]

Hi,

We have built 50 prototypes that has BMP280 in it to measure temperature and pressure. However, we discovered upon testing that 3 out of 50 devices shows incorrect pressure values (seen in the bottom right image). They all seem to be following the temperature pattern. Any help on what I could be doing wrong? They are all running the same firmware. All the devices seems to be reporting correct temperature value.

Hello mdmobashir,

Reweld BMP280, and the corresponding silk screen is U303 in your picture.
There was "Handling, soldering & mounting instructions" document for your reference.
