org.glassfish.json.JsonArrayBuilder error
As error message clearly tells you, you are trying to convert JSON array into JSON object.
"APs" is an array of several WifiAccessPoints.
I've tried to set it up as a JsonObject = field.getJsonObject("APs"), and access but still run into the same error.
Please provide information about new device, server logs with HEX samples and updated protocol documentation.

Also, quick question on testing.
I'm trying to run the code from the DmtHttpProtocolDecoderTest.java -- so technically, it should work, however I get this in response.

Are you using official version or your modified one?
Modified version, but tried with the official version and still seeing that issue. I can't seem to POST the JSON. I'm getting:
curl: (52) Empty reply from server
Fixed. Please try now.
Now working perfectly. Thanks for that!
Alrighty, so I'm working on the geolocation aspect. I'm unsure how GeolocationHandler gets triggered?
I've set the position.setValid(false), and position.setNetwork(network) and have geolocation.processInvalidPositions set to true.
DmtHttpProtocolDecoder.java
...
if (network.getCellTowers() != null || network.getWifiAccessPoints() != null) {
position.setValid(false);
position.setNetwork(network);
}
GeolocationHandler.java
...
position.getOutdated() || processInvalidPositions && !position.getValid()) && position.getNetwork() != null
Check other decoders for examples.
I checked several but unsure what actually triggers geolocation.
The other decoders for example Smokey, just shows adding WiFi access points to network and setting network.
It seems from the conditions above should trigger geolocation, but it does not.
Just debug the code and see what happens.
There's a new DmtHttpProtocol tracker that only uses WifiAccessPoints, so no lat/lng, and needs to geolocate each time through for example Google.
I am however receiving an error on the JsonObject, and I've tried everything. Is there something related to how it works that I'm missing?
{ "SerNo": 100000, "IMEI": "#", "ICCID": "#", "ProdId": 72, "FW": "72.2.1.3", "Records": [ { "SeqNo": 53, "Reason": 11, "DateUTC": "2019-01-18 18:52:45", "Fields": [ { "APs": [ { "MAC": "00:00:00:00:00:00", "Sig": -44, "Ch": 11 }, { "MAC": "00:00:00:00:00:01", "Sig": -46, "Ch": 11 } ], "FType": 25 }, { "Towers": [ { "CID": 00000000, "LAC": 00000, "MCC": 000, "MNC": 000 } ], "FType": 28 }, { "DIn": 0, "DOut": 0, "DevStat": 0, "FType": 2 }, { "AnalogueData": { "1": 4503, "3": 2627, "4": 17, "5": 4516 }, "FType": 6 } ] } ] }I've done the following:
import org.traccar.model.CellTower; import org.traccar.model.Network; import org.traccar.model.WifiAccessPoint; ... case 25: JsonArray waps = field.getJsonArray("APs"); for (int k = 0; k < waps.size(); k++) { JsonObject wap = waps.getJsonObject(k); network.addWifiAccessPoint(WifiAccessPoint.from( wap.getString("MAC"), wap.getInt("Sig"), wap.getInt("Ch") )); } break; case 28: JsonObject ct = field.getJsonObject("Towers"); network.addCellTower(CellTower.from( ct.getInt("MCC"), ct.getInt("MNC"), ct.getInt("LAC"), ct.getInt("CID") ));
