FX30 ADC read from the console

Good morning,

I am using an FX30 from the Linux console (SSH connection) and I would like to use the ADC1 (pin 5, IO2 of the power cable).

The read command always reports the same value regardless of of the power I apply on the PIN5.

Command used: 
       $> cat /sys/class/hwmon/hwmon0/device/mpp_05
Response obtained:
            Result:9948 Raw:24796

As required by the FX30 user manual, I set the pull-up OFF by the following command:
$> echo 0 > /sys/class/gpio/gpio53/value

Could you advise on the commands to use to obtain a good reading?

Best regards, Christian.

Please contact Sierra Wireless support/ Distributor for this issue.

Thanks & Regards,
