Grillo Slide Troubleshooting

Slide devices sleep between cycles, so most checks mean waiting for the next 6-hour slot: 00:00, 06:00, 12:00, or 18:00 UTC.

Grillo Field app​

The app does not connect to the basePower the base off and on, then hold the SETUP button (on the board under the battery holder, cover off) for 2 seconds within 10 seconds of power-on. Bluetooth stays open for 2 minutes. Keep the phone close, with Bluetooth on and the app's permissions allowed.

Nothing arrives on the dashboard​

  1. Wait for the next 6-hour slot to pass, then refresh.
  2. Check that the base has power and its solar panel is connected.
  3. Check the SIM is active, has data, and has coverage at the base.
  4. Set the APN again. A wrong APN stops every upload and cannot be fixed remotely.

If the base cannot upload, readings from the rovers do not reach the dashboard either.

A rover is missing or overdue​

  • Check its power and solar panel.
  • Check its GNSS antenna is connected.
  • Check it is within radio reach of the base or another rover. Try moving it closer for one cycle to confirm.
  • If you powered devices on in the wrong order, wait for the next slot. All devices meet again at the next 6-hour mark.

A rover reports but shows no movement value​

The rover reached the base but did not get a precise position fix in that cycle. It gives up on a fix after 7 minutes.

  • Give its antenna a clearer view of the sky.
  • Check the base also has a clear sky view; rovers depend on its corrections.
  • Look at the next cycle. A single missed fix is not a fault.

Movement looks wrong​

  • Every rover jumped by the same amount: the base or its antenna moved. Put it back or fix it in place, remove the cover and press the base's RESET button to survey it again, then reset the baseline for the sensor group.
  • One rover jumped: check its mount and antenna, then reset that rover's baseline.
  • Readings scatter by a centimetre or two: this is normal for single readings. Look at the trend over several days.
