SODAQ LPS22HB Arduino Example

Why the I2c sensor is unable to function on SODAQ shield ?

I have connected scl/sda/rx/tx to appropriate pins still no success and why we are getting value 0.00 mbar… ? when the I2c itself is not working

Failed to connect!
Error while retrieving WHO_AM_I byte…

For the i2c components on the NB-IoT shield, make sure to attach the IOREF pin of shield.

Depending on what IO levels your board uses, the IOREF pin should be connected to either 3.3V or 5V.

(I assume that you have also connected the shield’s 3.3V and GND pins.)
