Hi,
Your subscriber should be instantiated outside of your loop:
int main(int argc, char **argv)
{
init(argc, argv, "testPlayer");
NodeHandle n;
Subscriber sub;
sub = n.subscribe("scan", 1000, &testPlayer::callBack, &test);
Rate loop_rate(5);
testPlayer test;
while ( ok() ) {
spinOnce();
loop_rate.sleep();
}
return 0;
}
This should work normally.
Cheers,
Ugo
Hey everyone
I got a small problem writting a subscriber using the spinOnce command instead of the spin() used in the tutorial. I do not receive anything from the subscription, but I know topics are being published. rviz is showing that the data is published and if I rewrite the code to use spin() like in the tutorial, then I get plenty of information. I have tried to search the problem but did not find anything useful and I hope someone here can see the problem.
My code is:
