Ansible script
The playbook was not working for me, I had this error:
ERROR! 'apt' is not a valid attribute for a Play
The error appears to have been in '/root/coap_testing_tool/ansible/main.yml': line 1, column 3, but may be elsewhere in the file depending on the exact syntax problem.
It seems we need to add hosts at the beginning of the playbook.
So I added this:
hosts: all
sudo: yes
