EVAL-CN0429-EBZ resetting sensor values settings after reboot

Hi everyone,

I'm currently using the EVAL.CN0429-EBZ board togheter with EVAL-M355-ARDZ for gas mesurements. I'm using Alphasense SO2-A4, NO2-A43F and NO-A4 sensors and I need to set the correct parameters in order to use them correctly. The problem is that after a power down, shutdown or restart all the sensor values that I set are gone.

When I plug the board, the " DETAILES.TXT " file is showing this info: 

# DAPLink Firmware - see https://mbed.com/daplink
Unique ID: 0600000053454e4500268004006e0046aa21000197969900
HIC ID: 97969900
Auto Reset: 0
Automation allowed: 0
Daplink Mode: Interface
Interface Version: 0242
Bootloader Version: 0242

USB Interfaces: MSD, CDC, HID
Bootloader CRC: 0xb3954be4
Interface CRC: 0x8e62b75b

Is the " Auto Reset " entry the problem in my case? how can I change it?

After that, related to the parameter setting, there is the Alphasense NO2 sensor that has negative sensibility ranges but I cannot insert any negative value in the command line, what can I do? 

Is it there a way to connect the EVAL-CN0429-EBZ connected to the EVAL-M355-ARDZ directly to an arduino and read the data with the I2C? 

Thanks everyone, I really need help as I have strict deadline coming up.
