I’m exploring the possibility of integrating the Teltonika FMB920 with a biometric time clock (e.g., fingerprint or facial recognition device) to enhance fleet management by combining driver authentication with GPS tracking. My goal is to receive biometric data—such as DriverID and Timestamp—via Bluetooth, pair it with GPS coordinates (Latitude and Longitude), and send it to my server in real-time using the FMB920’s GPRS functionality. I’d appreciate your insights, experiences, or suggestions on whether this is feasible and how to achieve it.
Any help, resources, or insights would be greatly appreciated.
The biometric device has not yet been implemented with FM920 > Bluetooth, but you can still pair the device and use Data Link Mode. With the paired device, you can send messages of biometric device to the server,
Since this has not been tested yet, the outcome will depend on the testing results.
Thank you for your prompt response and for pointing me toward the Bluetooth settings documentation for the FMB920! I appreciate the clarification that biometric device integration hasn’t been implemented yet with the FMB920 via Bluetooth, but the suggestion to use Data Link Mode is intriguing. I’d like to dive deeper into this option and explore alternatives as well.
Regarding Data Link Mode with the FMB920:
Could you elaborate on how Data Link Mode could be used to send biometric data (e.g., “DriverID:12345, Time:1741742400”) from a paired biometric time clock to the server? Does it allow the FMB920 to relay raw data as a string or packet without needing to interpret it, or would firmware customization still be required to assign AVL IDs (e.g., 250 for DriverID, 251 for Timestamp) and include them in Codec 8/8E packets?
Since you mentioned this hasn’t been tested, are there any known examples of Data Link Mode being used with other Bluetooth devices (e.g., sensors) that might give me a starting point for testing with a biometric clock?
If successful, would the Configurator allow me to configure how the biometric data is handled, or is this purely a server-side decoding task?
On alternatives to the FMB920:
Are there other Teltonika devices that might offer better native support or easier integration with a biometric time clock via Bluetooth? For instance, do any models have more advanced Bluetooth capabilities (e.g., v4.0 or higher) or serial ports (RS232/RS485) that could simplify wired or wireless biometric integration?
If firmware customization is needed regardless, would a higher-end model reduce the complexity or cost of adapting it to process biometric data and send it with GPS coordinates?
I’m aiming to receive “DriverID” and “Timestamp” from a Bluetooth-enabled biometric clock , combine it with GPS data, and send it to my server in real-time. Any additional guidance on testing Data Link Mode or recommendations for alternative devices would be greatly appreciated. I’d also be happy to share my testing results with the community once I get started!
When the Bluetooth → Data Link mode is configured and when an external device is connected via BT, the information received via BT channel to the tracker should be sent in Teltonika codec 12 format to the server specified in the tracker settings and vice versa.
You can check the codec 12 data structure and format from link https://wiki.teltonika-gps.com/view/Codec#Codec_12
Hello @Maryam
Thank you again for the detailed clarification, i’m going to proceed with testing the Data Link Mode approach with the FMB920 and a Bluetooth-enabled biometric time clock. I’ll report back to the community with my results—whether it works smoothly or if I run into challenges. If successful, this could be a helpful reference for others!
Thanks for your guidance, and I’ll keep you posted.
