Problem working with H3LIS200DL (+-200g accelerometer)

Hi, I am using H3LIS200DL with RFduino (RFD22102 ) as microcontroller, I have used the schematic given in data sheet except I have connected CS pin to Vdd (for using I2C). Also, I am using Arduino H3LIS331Dl_demo code attached below.



The IC works fine for 5mins and then readings become constant. And when I use it again after 10 hours or so, it again works fine for 5mins only. This is happening from 3 days. I have also resoldered it and rechecked the capacitors.

I used 3 ICs. One worked fine but the same problem is happening with other 2.



Is this any soldering problem?

Am I missing any point?

Help would be appreciated.
