10. Connection modes

Connection Modes

x3utils has three persistent connection modes.

The selected mode is saved by the launcher and stays active until changed.

Use this when SWD is available normally, or when the scooter can enter a service mode by holding the turn indicator buttons during power-up.

Use this with common clone ST-LINK adapters.

Many clones do not have a working reset pin, so x3utils guides the user to touch C45 to GND during connection.

Use this with a genuine ST-LINK adapter or working Nucleo ST-LINK reset output connected to the chip reset line.

Mode B also exposes a countdown timer. Increase it if you need more time during the manual C45-to-GND step.
