Waiting for service to become available

[stphnlght]

Any help will be much appreciated, I keep getting the result below but the service is available in the service list. The service is ‘find_wall’.

user:~$ ros2 service call /find_wall std_srvs/Empty '{}'
waiting for service to become available...

user:~$ ros2 service list
/apply_joint_effort
/apply_link_wrench
/clear_joint_efforts
/clear_link_wrenches
/delete_entity
/find_wall

Thanks in advance for the help.

Hi @stphnlght ,

Welcome to this Community!

I think your command is wrong. I believe the command should be as follows:
ros2 service call /find_wall std_srvs/srv/Empty '{}'

Try this and let me know if that worked for you.

Regards,
Girish

Can you check that your service is still running in the terminal where you are running it. It could have crashed, for instance.
