A device may experience problems obtaining a GPS fix. In some cases, no data is registered, resulting in GPS being unavailable. SMS command responses can still be received, and it is important to note that SIM availability is not related to the GNSS module or this issue.
When this type of problem occurs, event generation may be interrupted, and consequently, no data will be received by the server.
Explanation:
If the device does not obtain a valid timestamp from either the GNSS or the network, the coords command response will be: GPS is not available.
Guidelines:
When the device responds “GPS is not available” to a coords command request, even though the SIM is online and receiving commands, the most common causes include:
• Physical obstruction of the antenna (installation in a location without sky view)
• interference in the installation area
• Damaged GNSS module
Troubleshooting Steps:
1. Verify the GNSS settings in the configuration file:
2. Validate correct device installation: ensure the unit has clear sky access and that the case label “this side towards sky” is facing upward
3. Send an SMS command log and share it with technical support. Use the following command: getlog 192.168.21.104,2905,1,30 (Note: the IMEI number of the device will be required.)
Additional Notes:
• The coords command must return state 3 to confirm a valid GPS fix. States are described below:
• Support is provided exclusively for TrustTrack as the fleet management system. For third party platforms such as Wialon, support is limited to basic device configuration
