Hello Andrew Murphy,
Good day. Thank you for your question.
If you use EYE app, you can see approximate distance(Beacon - smartphone) if beacon and smartphone is in the range of Bluetooth. It is possible to determine movement, distance, but not direction, since BTSID1 does not have GNSS.
For more detailed information about BTSID1 please refer here:

If you have more detailed questions you can always reach us via VIP Helpdesk on our official website https://teltonika-gps.com/ .When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to info@teltonika.lt
Thank you for your understanding.
Kind regards.
