HD_COMM_ERROR while starting the launch file about ros_geomagic_touch_phantom_omni HOT 3 CLOSED

Hey @VictorKingbot.

Sorry about the delay in replying. I didn't check my notifications 😅 (I also didn't think anyone would be using the package 🙈)

First off. I haven't tested this against ROS Kinetic and I only have the USB version of the Touch so some of it is guess work. Im using ROS Melodic (I wanted jogging and the servo package gives me that in Melodic). All my work is on the development branch (not much at the moment). If you use that branch make sure to change the name here: https://github.com/jdrew1303/ros_geomagic_touch_phantom_omni/blob/develop/omni_driver/src/omniethernet.cpp#L122 It's not recognising the default device name. I haven't had time over the past few days to push some changes I've been working on. I should get to them next week.

Some issues that I've found with it that might help debugging your issues are:

• Make sure you only have a single config/setup generated. If you have multiple ones created the drivers can throw a connection error. Sometime you'll have a default config and the named config you created (Phantom Omni). Check in the config folder you had to create as part of the setup.
• If you're working in a VM the layer that virtualises the network (or in my case the USB device) introduces lag and jitter that can cause a communication failure. I only found this out with help from the Geomagic team. If you check the servo tab and have it run a diagnostic. Anything over 650-700 should be fine (not good but it should work). Ideally you want the graph green and the values around 1000.

Hopefully this helps a bit. Let me know. 👍

Thanks! @jdrew1303 I switched to the Ubuntu18 and reinstalled the driver, now the issue has been resolved. And I really appreciate your work, it helped me a lot!👏

Hey @VictorKingbot

Glad you got things working 🙋‍♂️

If you're using this for research or development it would be good to keep in touch. It would be cool to see what people are using this for. If theres a lot of people working on similar stuff it could be good to make contacts and share research. 👍

All the best.
James
