Communication error using UART to USB

[Danilrivero]

Hello,

I have bumped into the following issue when trying to connect to the BNO055. I made sure it properly works beforehand by using a small Arduino snippet and it does.

I get the following message when running the node configured with the yaml file.

CP2104 and connections work properly and the tty/USB0 port is properly attached:

I am using Ubuntu 22.04 with ROS2 Humble and all the libraries required to run the driver are installed.

The only parameter changed is the baudrate due to my requirements:

Has anyone bumped into this issue before? Any advice on how to proceed? The response header 0xff does not give me enough information to deal with it.

Thank you for creating your first issue on this repo! Give me some time to review and respond to your problem.

To add more information:

• If I use a baudrate of 115200 I get the following error:

• Drivers for the USB to UART adapter seem to be installed properly:

• Tried giving rw permissions to tty/USB0 manually as well:

I can send more information if required.

hey @Danilrivero! I haven't actually had a bno055 to test this driver in awhile - but from what I can tell the last change to the UART side of things for this driver was this commit. Could you maybe try to revert that change and see if UART works?

I really need to get around to adding some integration tests to this repo...but havent had much time unfortunately.

Hello @flynneva that seems to be the issue. Thanks for your comment!

Closing the issue due to the fix being found.

@Danilrivero ok awesome. I'll go ahead and remove this change from main then, thanks for confirming that reverting that line fixed it!

@emilnovak see the thread above. Since you authored the problem commit here, could you give some background on why you made that change / what it fixed for you?

Maybe we are just missing an if / else somewhere

Sorry for the late reply @flynneva, I completely missed this thread. For future reference the reasoning can be found here: #52 (comment). I may be able to look further into this problem, since I'm actively using some BNO sensors with this change via serial.

@emilnovak no worries! I know how it goes - I haven't touched this repo in a long time either. I might have some time this week to put a bit of work in here as well...let's see 👍
