Initializing ROS master on http://172.30.38.188:58842.
Initializing global node /matlab_global_node_45959 with NodeURI http://dcc663585glnxa64:46815/ and MasterURI http://localhost:58842.

Set up a service server. Use structures for the ROS message data format.

server = rossvcserver('/test', 'std_srvs/Empty', @exampleHelperROSEmptyCallback,...
                      'DataFormat','struct');
client = rossvcclient('/test','DataFormat','struct');

Check whether the service server is available. If it is, wait for the service client to connect to the server.

if(isServerAvailable(client))
    [connectionStatus,connectionStatustext] = waitForServer(client)
end

connectionStatus = logical
   1

connectionStatustext = 
'success'

Call service server with default message.

response = call(client)

response = struct with fields:
    MessageType: 'std_srvs/EmptyResponse'

If the call function above fails, it results in an error. Instead of an error, if you would prefer to react to a call failure using conditionals, return the status and statustext outputs from the call function. The status output indicates if the call succeeded, while statustext provides additional information.

numCallFailures = 0;
[response,status,statustext] = call(client,"Timeout",3);
if ~status
    numCallFailures = numCallFailues + 1;
    fprintf("Call failure number %d. Error cause: %s\n",numCallFailures,statustext)
else
    disp(response)
end

    MessageType: 'std_srvs/EmptyResponse'

Shut down the ROS network.

* Exiting killProcessByPID function *

Call ROS 2 Service Client With a Custom Callback Function

Open Live Script

Create a sample ROS 2 network with two nodes.

node_1 = ros2node('node_1_service_server');
node_2 = ros2node('node_2_service_client');

Set up a service server and attach it to a ROS 2 node. Specify the callback function flipstring, which flips the input string. The callback function is defined at the end of this example.

server = ros2svcserver(node_1,'/test','test_msgs/BasicTypes',@flipString);

Set up a service client of the same service type and attach it to a different node.

client = ros2svcclient(node_2,'/test','test_msgs/BasicTypes');

Wait for the service client to connect to the server.

[connectionStatus,connectionStatustext] = waitForServer(client)

connectionStatus = logical
   1

connectionStatustext = 
'success'

Create a request message based on the client. Assign the string to the corresponding field in the message, string_value.

request = ros2message(client);
request.string_value = 'hello world';

Check whether the service server is available. If it is, send a service request and wait for a response. Specify that the service waits 3 seconds for a response.

if(isServerAvailable(client))
    response = call(client,request,'Timeout',3);
end

The response is a flipped string from the request message which you see in the string_value field.

response.string_value

ans = 
'dlrow olleh'

numCallFailures = 0;
[response,status,statustext] = call(client,request,"Timeout",3);
if ~status
    numCallFailures = numCallFailues + 1;
    fprintf("Call failure number %d. Error cause: %s\n",numCallFailures,statustext)
else
    disp(response.string_value)
end

dlrow olleh

The callback function used to flip the string is defined below.

function resp = flipString(req,resp)
% FLIPSTRING Reverses the order of a string in REQ and returns it in RESP.
resp.string_value = fliplr(req.string_value);
end

Input Arguments

collapse all

`client` — ROS service client
`ros.ServiceClient` object handle | `ros2serviceclient` object handle

ROS or ROS 2 service client, specified as a ros.ServiceClient or ros2serviceclient object handle, respectively. This service client enables you to send requests to the service server.

Output Arguments
