No GPRS Alert

Modified on Thu, 31 Aug 2023 at 04:17 PM

Understanding the Oyster's Operational Behavior:

The Oyster tracker is designed with power efficiency in mind. Here's how it operates:

  1. Sleep Mode: Once the Oyster stops moving, it goes into a 'sleep' mode 5 minutes post the cessation of motion. This is a power-saving feature to extend the battery life of the device.

  2. Scheduled Check-In: When stationary, the Oyster is set to check in every 12 hours. This means that if the device hasn't moved, it will only communicate its status twice a day.

Recommended Alert Setting:

For the most accurate notifications regarding GPRS connectivity with the Oyster, it's suggested to:

  • Set the "No GPRS" alert to 18 hours. This timeframe ensures you're notified only when the device hasn't checked in beyond its typical 12-hour interval, allowing a buffer for potential delays or minor disruptions.


Fine-tuning your alert settings can significantly enhance your experience with the Oyster tracker. By understanding the device's operational behavior and adjusting settings accordingly, you can ensure you receive relevant notifications without unnecessary alarms.
