When should I see an rcl node show up in rqt_graph?
I am working with rcl
directly and from what I can tell have succeeded in initializing a node. I can queury its name and get a true
result when checking its validity (via rcl_node_is_valid()
), however, the node does not show up as I had expected as a sanity check (when running an instance of rqt_graph
in another terminal). Running > ros2 node list
also does not show any indication of success.
My question is: at what point through the rcl
API should I be able to see my node? So far I have done the following:
init_opts = rcl_get_zero_initialized_inti_options();
context = rcl_get_zero_initialized_context();
alloc = rcl_get_default_allocator();
rcl_init_options_init(init_opts, alloc);
rcl_init(init_opts, context);
node = rcl_get_zero_initialized_node();
node_opts = rcl_node_get_default_options();
rcl_node_init(node, "node_name", "node_ns", context, node_opts);
Am I missing something before I can see my node?
Thanks, Brett
UPDATE (6/16):
I worked some more on this today and was able to see my node in the graph after initializing a publisher for the node in question. Using a demo_nodes_cpp
to test I am still, however, not getting the first (few) published messages but it seems stable after the first receipt.
