we've implemented special logic for parsing BLE connected devices. Teltonika protocol send it under tag 385 and now it is parsed to parameter ble.beacons which is JSON object, where keys are BLE beacons UUID, and values - JSON objects with beacon parameters, e.g.
{...
"ble.beacons": {
"E2C56DB5-DEAD-BEEF-B060-D0F5A71096E0:1234:9876": {
"rssi": -79
},
"E2C56DB5-DEAD-BEEF-B060-D0F5A71096E0:4321:6789": {
"rssi": -86
}
},
"channel.id": 12345,
"event.enum": 385,
"event.priority.enum": 0,
"ident": "123451234512345",
"position.altitude": 126,
"position.direction": 60,
"position.latitude": 12.3456,
"position.longitude": 65.4321
...}
