rf_sensor

ROS node for radio frequency based sensors

Python scripts on src/rf_sensor can be used to run rf_sensor without ROS.
See notebooks/Standalone rf_sensor.ipynb for examples on how to use them.

Dependency

• ROS node rf_msgs containing ROS message definitions

Running iwconfig and ifconfig as passwordless sudo

It is recommended to modify sudoers to allow your user to run ifconfig and iwconfig as sudo without password. If the node is run with rosrun there are no issues. Password is asked once. However, when run from roslaunch it asks every time (in a loop) so not practical. No idea what is causing this behaviour

To modify your sudoer

sudo visudo 

Go to the end of the file and add

your_user_name ALL=(root) NOPASSWD: /sbin/iwconfig, /sbin/ifconfig

replace your_user_name by the name of your user
