Running 2022 FRC Driver Station and Labview code, Romi disables all outputs after 1.5 seconds

[Cap127]

Looks like wpilib-ws-robot-romi implemented PR #95 and wpilibsuite/wpilib-ws-robot#26. Leveraging the constant messaging from the driver station we are able to determine if we are still receiving messages from wpilib. If we don’t receive a message in 500 ms we will kill the heartbeat to the Romi which is checked every 1 sec setting a max overrun of 1.5 sec.

This is the exact cause of the issue as the motors will be re-enabled by switching modes on the Driver Station.

Turning on the Romi’s console output this is confirmed as the monitored FRC DriverStation Heartbeat appears only to be active on DriverStation mode change of state

Romi’s console output…

Looks like the updates made in wpilib-ws-robot-romi would not be compatible with FRC Labview and FRC labview based Driver Station for Labview code learning.

This was Confirmed by…
reverting from latest release
WPILibPi_image-v2022.1.1-Romi.zip
to
WPILibPi_image-v2021.2.1-Romi.zip (which does not have PR [#95] implemented )
allows the Romi to run without shutting the motors down after 1.5 seconds

[Cap127]

Running Romi Web Service v1.1.4 and WPILibPi 2022.1.1 Release 1.5 second timeout does NOT occur.
Update implemented in Romi Web Service v1.1.5 broke the ability to run 2022 Driver Station and Labview programs.
When enabled, the drives will run 1.5 seconds and then stop due to the updates made in Web Service v1.1.5 and carries fwd.

When can a fix be implemented?

Consider requiring a Heartbeat in the users program since it runs on the users computer and communicates via Websocket to the ROMI.
