DigitalMatter Oyster/Yabber
Why dont you write more context ?
Have you upgraded ?
Which version of traccar server are you using?
Using 5.10.
I have not updated, but i know DigitalMatter have updated. The Forwarder at DigitalMatter give this error:
Have you tried the latest version of Traccar?
Do you have an updated protocol documentation?
Not that I know what is going on, but I have looked at and talked to Digital Matter, and that error looks like there is an error on the Digital Matter forwarder configuration or, else, a mismatch between that configuration and the Traccar endpoint.
Did you see the message being sent in the Traccar logs?
Just a guess.
Tony; The decoded HEX is from Traccar log.
Do you use DM trackers and maybe want to share your config? Worked before. But stopped like 52 days ago..
We looked at them, but didn't carry on with the deal, didn't quite suit our market.
Have you asked DM if they changed the format at all? I have been writing my own integrations between our legacy tracking system, and Traccar, and have found that sometimes a change in network or system permissions have temporarily blocked the system.
Yes. Have contacted them, but not any luck so far.. Will try to update Traccar tomorrow:)
Here are traccar-log after update:

Not sure why we need to ignore the unknown device. Can you elaborate?
That is not a real device.
See response from support here.
Not sure how familiar you are with Digital Matter's Forwarder, here a diagram for reference.
OK, but then what's the point of this test?
Not sure...
Just did a test.
Captured the test output from DM. Manually posted that to Traccar: {"date":"2025-03-17T16:28:16.4048802Z","device":{"sn":"1111111","prod":105,"rev":2,"fw":"4.6","module":"353","iccid":"89349493467812254594","imei":"932107325522097"},"sqn":6543,"reason":40,"lat":-22.116219895334325,"lng":-177.39340181963536,"posAcc":21.604855728667616,"alt":2245,"posInfo":{"GDOP":3.428375225541277,"HDOP":1,"PDOP":4,"BSat":11,"GSat":6,"Src":3},"analogues":[{"id":1,"val":4104},{"id":3,"val":6035},{"id":4,"val":73},{"id":5,"val":2378},{"id":12,"val":87},{"id":13,"val":-25},{"id":17,"val":354},{"id":18,"val":4984},{"id":19,"val":23},{"id":20,"val":-11}],"inputs":9,"outputs":0,"status":0,"counters":[{"id":0,"val":6859},{"id":3,"val":521},{"id":4,"val":7266},{"id":128,"val":1298},{"id":129,"val":67142},{"id":130,"val":91},{"id":131,"val":6310},{"id":142,"val":727084},{"id":145,"val":3281},{"id":146,"val":6}]}
and it returned 200 OK, after i added the random test IMEI 932107325522097 to the Traccar server, and sees to work. So the only real issue is the "pointless" test from DigitalMatter. If Traccar returns 200 OK when serial are 1111111, 2222222, 3333333, 4444444, 5555555, 6666666 or 7777777 it should work..
Did a temporary fix. Sendig all data to a PHP script, so DM always get a 2XX response. And then forward the data to Traccar.
<?php
// Get raw POST data
$rawData = file_get_contents('php://input');
// Prepare log entry with timestamp
$timestamp = date('Y-m-d H:i:s');
$logEntry = "[{$timestamp}] " . $rawData . "\n";
// Append to single log file
$logFile = __DIR__ . '/forwarder.log';
file_put_contents($logFile, $logEntry, FILE_APPEND);
// Setup curl request
$ch = curl_init('http://traccar.URL-xx.yy:5139');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $rawData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Forward headers
$headers = getallheaders();
$curlHeaders = [];
foreach ($headers as $key => $value) {
if ($key != 'Host') { // Skip host header
$curlHeaders[] = "$key: $value";
}
}
curl_setopt($ch, CURLOPT_HTTPHEADER, $curlHeaders);
// Execute request and get response
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
// Log the response code
$logEntry = "[{$timestamp}] Response Code: {$httpCode}\n";
file_put_contents($logFile, $logEntry, FILE_APPEND);
// Always return 200 OK regardless of forward response
http_response_code(200);
echo "OK";
// Force connection close
if (function_exists('fastcgi_finish_request')) {
fastcgi_finish_request();
} else {
flush();
if (function_exists('ob_flush')) ob_flush();
}
?>
Now it works, until it's finally fixed in Traccar :)
Have lost updates from my Digital Matter Oyster and Yabber devices.
Decoded HEX:
Protocol changed?
