I have a new laptop that I have installed WPILib 2024.3.2 on and am trying to get my Romi running under it. It runs under 23.whatever just fine but on the 24.3.2 it brings up the control panel for the Romi and there is nothing in the Other devices panel which shows the Romi gyro on the 23 version. The joystick works fine which you would expect since it is a local device to the PC.
I see a new thing on the Robot Stat that says Disconnected which is new but clicking on any of the other options doesn’t let you drive the Romi.
On the VS log section I get the following
Error at edu.wpi.first.wpilibj.MotorSafety.check(MotorSafety.java:140):
DifferentialDrive… Output not updated often enough. See
Using the WPILib Classes to Drive your Robot — FIRST Robotics Competition documentation for more information.
repeated over and over again
They just keep on coming. It appears that there is no communications between the Romi and the Sim on the PC.
Do I need to update the Romi so it works with the 24.3.2? I saw something posted in one of my searches showing it was for Vision processing. I hesitate to load it until I’m sure.
I probably missed something somewhere that would tell me but I seemed to be doing a circular search and times and thought I’d ask here.
Any help appreciated.
To clarify, you’ve imaged the Romi with the 2023.2.1 image, and it works with a WPILib 2023 project, but you can’t get it to connect when creating a new project with WPILib 2024? That should work (without updating the Romi).
Did you change the Romi network settings when setting it up? E.g. is it running as an AP, or is it connecting to a local WiFi network in bridge mode? There are some network settings that are stored at the project level in build.gradle, so if you created a new 2024 project, they wouldn’t have gotten transferred over. See this section of the docs for customizing the IP address of the Romi: Programming the Romi — FIRST Robotics Competition documentation If you look in your 2023 project, if that’s set there, you can copy it over and see if that fixes things.
I didn’t change anything from the stock programs in terms of networks or anything like that. I connect to the Romi just as if it were a router (which I guess you are referring to as an Access Point) I assume it is the 2023.2.1 image but don’t remember which one I installed. It works with 2023 First Romi programs in any case. The driver console does show connecting to 10.0.0.2 with 2 ports so they seem to be talking at least some.
I’m thinking I might just try creating a new image for the Pi on the Romi and see if that helps. I’m assuming you can re-image the Pi over and over and it will treat the Romi correctly. I just don’t know why the current version on the Romi won’t work with 24.x but does with 23.x unless it’s an earlier version than the 2023.2.1 image.
I’ll try this tomorrow since I think I’m going to be snowed in anyhow. 
Thanks for your help
More questions. Is there a way to determine the version of WPILibPI from the WEB interface to the Romi. (A 10.0.0.2 connection) I tried setting up a second Romi and it doesn’t seem to connect to the console. I installed WPILibPi_64_image-v2023.2.1-Romi and it doesn’t see to be working. I wonder if the image I have on the original Romi is in fact WPILibPi_64_image-v2023.2.1-Romi or an earlier version.
Another thing I have noticed. On the newer Romi, the The web interface says “Firmware Compatible No”
Further question Can I just dd the image off the working one and write it to a new microSD card and try that?
Sorry for all the questions but I’m not sure what to try at this point
Thanks for any suggestions
