2012-07-24 19:26:22 -0500 | answered a question | rosbridge how to subscribe from multi rostopic Thank you, It's helpful for me! |
2012-07-24 14:44:46 -0500 | answered a question | rosbridge how to subscribe from multi rostopic Actually, I can use "connection.addHandler('/a',function(msg) {.....});" to get msg from topic /a . I'm not sure there's any way to use msg from two topics in one handler. By the way, using your example I found that rsp is "OK" but not the msg from topic, so what does the rsp's content mean? just subscribe is successful? Thank you for your kindness! |
2012-07-24 11:21:20 -0500 | asked a question | rosbridge how to subscribe from multi rostopic I know that use such function I can use msg subscribe from the topic called /sensorPacket: connection.callService('/rosjs/subscribe','["/sensorPacket",0]',function(rsp) { alert('subscribed to /sensorPacket'); }); But I want information from 2 topics, for example /a and /b . How can I realize? can I just use in such way: connection.callService('/rosjs/subscribe','["/a,/b",0]',function(rsp) { alert('subscribed to /sensorPacket'); }); |

2012-07-20 11:38:21 -0500 | answered a question | rosbridge connection closed Thank you so much! Yep, there`s such bug in rosbridge download from source. It has been solved after I use the version checkout from svn. |
2012-07-20 09:28:01 -0500 | answered a question | rosbridge connection closed Thank you for your answer, but it still doesn't work. I'm using the latest chromium broswer. However I found that when I use ws://hostname:9090 ,there're nothing report under rosbridge, and when I change to ws://localhost:9090 and ws://127.0.0.1:9090 "closed 10" error will be reported under rosbridge's running One more thing ,when I test in latest Firefox, it will always report "error!" but in Chromium, it always be "connection closed"...It's strange... |
