<span style=" font-size:10pt;font-family:sans-serif">Hello Diego,<br>
</span>
<br><span style=" font-size:10pt;font-family:sans-serif">Just a quick check
that might be useful. Have you tried changing readNewest by a readNew?
</span>
<br><span style=" font-size:10pt;font-family:sans-serif">I had unexpected
behaviour with readNewest in the past, and found that readNew is doing
what I would expect from readNewest, as long as your port connection does
not have a buffer.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Maybe your issue
is unrelated but it should take you very little time to try.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Cheers,</span>

<br>
<br><span style=" font-size:12pt">Recently I had a problem on the component
`</span><span style=" font-size:7pt">auv_control:PIDController</span><span style=" font-size:12pt">`
going to `POSE TIMEOUT` state.</span>
<br>
<br><span style=" font-size:12pt">The point, however, is that looking to
the logs, the pose feedback component is writing samples on its output
port. So the `readNewest` </span><a href="https://github.com/rock-control/control-orogen-auv_control/blob/master/tasks/PIDController.cpp#L52" target=_blank><span style=" font-size:12pt;color:blue"><u>on

returning "RTT::NewData".</span>
<br>
<br><span style=" font-size:12pt">Additionally I found this message on
"orocos.auv_control_aligned_vel2body_effort-XXX.txt", related
to "mqueue" that may be related to this issue: </span>
