LapBrain supports direct sync from AiM Solo 2 and Solo 2 DL data loggers. You can also export their XRK/XRZ files from Race Studio 3 and upload them manually.

If you have the LapBrain mobile app on your phone or tablet:

  1. Power on your Solo 2 or Solo 2 DL and connect to its WiFi network
  2. Open the LapBrain app and tap Sync
  3. The app discovers your data logger and downloads new sessions automatically
  4. Sessions upload to LapBrain and processing begins immediately
tip

Direct sync avoids a separate file-export step. You can sync in the paddock after a session; the app shows upload and processing progress until the session is ready.

Manual export

If you prefer to export files from Race Studio 3:

  1. Connect your data logger to your computer via USB
  2. Open Race Studio 3 and download the session
  3. The session file (.xrk or .xrz) is saved to your Race Studio 3 data folder
  4. In LapBrain, open the LapBrain menu, choose Sessions, tap + in the Sessions panel header, then Choose files, and pick the file

LapBrain accepts both .xrk and .xrz files directly.

Channel requirements

LapBrain requires GPS data for track map generation and corner analysis. Solo 2 and Solo 2 DL record the necessary GPS channels.

warning

Without GPS data, LapBrain cannot provide a track map, corner analysis, or coaching recommendations. Make sure GPS is enabled in your data logger's configuration.

Models that work with LapBrain

  • Solo 2: internal GPS and WiFi sync
  • Solo 2 DL: internal GPS, WiFi sync, and CAN channels when configured

Troubleshooting

Your data logger isn't in the list yet

An AiM data logger can take up to a minute after you switch it on to start broadcasting its WiFi network. If the device list comes up empty, that is usually all it is: close the list, give the data logger a few more seconds, and tap again. It often takes two or three looks.

tip

Nothing needs resetting while you wait. The data logger is booting, and its WiFi network simply is not up yet.

If a download gets stuck

Occasionally a data logger stops sending partway through a download. LapBrain holds the transfer open and tries to continue on the same connection. If those attempts do not restore progress, it keeps waiting for the data logger. Keep the app open and stay connected; the download continues automatically if data resumes. If the transfer does end early, your sessions stay on the data logger and the next sync collects them.

If the sync ends and your data logger has stopped responding:

  1. Check the data logger. Check whether its buttons respond. If they do, try syncing again. If they do nothing, restart the data logger before another attempt.
  2. Sync again if it is responding. Start another sync from your device list.
  3. Not responding? Restart the data logger. Hold its power button for about two seconds, release, and try again after a few seconds. It may take several tries over a few minutes. Once it powers off, switch it back on, give it up to a minute to start broadcasting its WiFi network, then sync again.
tip

Your data logger's buttons stop working while it is sending data, the same as any other download. Leave it switched on until the sync finishes: turning it off partway just ends the transfer, and that session downloads again next time.

AiM sync can't find your data logger on iPhone or iPad

Direct sync connects to your Solo 2 or Solo 2 DL over its own WiFi network, so on iPhone and iPad the LapBrain app needs the Local Network permission to discover the data logger. The first time you sync, iOS shows a one-time prompt asking LapBrain to find devices on your local network.

If you tapped Don't Allow on that prompt, iOS silently blocks LapBrain from seeing the data logger, so Sync never finds it, even though your WiFi connection and the data logger itself are working fine. iOS does not ask again, so retrying discovery alone won't fix it.

To re-enable it:

  1. Open the iOS Settings app.
  2. Go to Privacy & Security → Local Network.
  3. Turn on the switch for LapBrain.
  4. Return to the LapBrain app and tap Sync again.
tip

This is an iOS permission, not a hardware fault; your data logger doesn't need resetting. Once Local Network is enabled for LapBrain, discovery works normally. (Bluetooth data loggers like RaceBox use a different permission and are not affected by this setting.)

What to do next

  1. Upload your first session: see Your First Session for what happens after upload.
  2. Check your GPS: if your track map looks wrong or corners aren't detected, verify GPS is enabled and has a clear sky view.
