Describe the bug
Most of the time, the publishers and services will not start on connection to the host ROS2 system
They will be listed in the ros2 topic list and ros2 service list command outputs, but calling the services or echoing the topics will not yield any output.

To Reproduce
Steps to reproduce the behavior:

1. Boot board
2. Connect to ROS2 host over agent serial connection (baudrate=115200)
3. Execute ros2 topic list or ros2 service list
4. Attempt to call either topic (ex: ros2 topic echo /angular_position) or service (ex: ros2 service call /set_motor_direction motor_interfaces/SetMotorDirection "{direction: false}"
5. See error

Expected behavior
Topics and services should show up and be live as soon as ROS2 agent is connected
