Please assist if possible,

I am using an Arduino UNO as well as a ESP8266 card with a BMP280 installed

I am using the following sketch to try to get familiar with this operation

SparkFun_BME280/I2C_ReadAllData.ino at master · mhaack/SparkFun_BME280 (github.com)

On the serial port I am getting a "0" reading for Temp C and "0" Pa which possibly accounts for an extremely high Altitude reading.

From my untrained eye, this looks like a calibration issue but I am probably wrong. Possibly a coding issue.

I cannot see what the issue is.
