Quick SMS Configuration

The default configuration provides optimal parameters for tracking quality and data usage. You can quickly set up your device by sending the following SMS command:

Note: Insert two space symbols before the SMS text.

GPRS SETTINGS:

• 2001 – APN
• 2002 – APN username (leave empty if none)
• 2003 – APN password (leave empty if none)

SERVER SETTINGS:

• 2004 – Domain
• 2005 – Port
• 2006 – Data sending protocol (0 – TCP, 1 – UDP)

Example SMS command: setparam 2001:internet; 2002:internet1;2003:internet2; 2004:avl2.teltonika.lt 2005:12050;2006:0

Default Configuration Settings

Movement and Ignition Detection

Movement is detected by the accelerometer. The device records data when moving if:

• The angle difference between the last coordinate and current position is greater than 10 degrees.
• The speed difference between the last coordinate and current position is greater than 10 km/h.

The device records data when stopped if:

• The angle difference between the last coordinate and current position is greater than 10 degrees.
• The speed difference between the last coordinate and current position is greater than 10 km/h.

Records Sending to Server:

• Records are made every 120 seconds while moving.
• Records are sent every 600 seconds while stopped.

After successful SMS configuration, the TMT250 will synchronize time and update records to the configured server. Time intervals and I/O elements can be adjusted using the Teltonika Configurator or SMS parameters.

Troubleshooting

TMT250 Doesn't Send Data to Your Configured Server:

• Check if the device is powered on.
• Ensure the SIM card is inserted correctly.
• Verify the device has registered to the network.
• Confirm Data Acquisition settings are configured correctly.
• Check if APN, Domain, and Port are entered accurately.

If the Device is Not Detected by the PC or Configurator:

• Ensure the device is powered on and the battery is sufficiently charged.
• Try a different COM port.
• Use a different Micro-USB cable.
• Reinstall the Teltonika COM Driver.
• Reinstall MS .NET Framework.
