• execute "snappy-remote --url=ssh://<address-of-your-ubuntu-core-device> install ./python-m2mlabs-sample_0.1_all.snap" to perform a remote download to the Ubuntu Core device. You will be asked three times for the password of the user on your Ubuntu Core device. Please ignore any warnings</address-of-your-ubuntu-core-device>
• you can change the config data on the Ubunto Core device with "sudo vi /apps/python-m2mlabs-sample/current/config/config.txt"
• on the Ubunto Core device execute python-m2mlabs-sample.m2mlabs-send
