Thanks for reaching out.
I'm not sure why you are having those errors, but I have found that UPM has an example for this sensor, so the best recommendation that I can give you is to test it. Please follow the next steps:
1. In case you need to install UPM, use the following commands:
echo "src mraa-upm http://iotdk.intel.com/repos/3.5/intelgalactic/opkg/i586" > /etc/opkg/mraa-upm.conf
opkg install mraa
opkg install upm
2. Once you have installed UPM, use the next example: https://github.com/intel-iot-devkit/upm/blob/master/examples/python/pn532.py
Try to use the example as a reference for your own code. We don't have this sensor to test it, so please let us know if it works.
I hope you find this useful.
