Good day. Thank you for the question.
For the BLE advanced functionalities, there are plans to increase it to 5 from the current 4 sensors but currently we do have the firmware for testing. If you would like to receive the firmware versions for testing and instructions, please contact your direct sales manager or distributor from which you bought the devices if you did not buy the directly from us
Additionally, there is the universal beacon solution which allows you to receive BLE data from any BLE sensor/beacon (up to 100 beacons/sensors), however you have to parse it from the server side because data is not saved into separate I/O elements. Similar as the option above, you will need to contact your sales manager to receive the firmware and instructions for testing purpose.
If you don't have any contacts with our Sales managers, please contact with them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with description to [email protected]
Thank you for contacting us. Have a nice day.
