New protocol implementation
Looks like this format is not supported yet. Do you have a protocol documentation?
Hi Anton,
Can I use same logic as u did for osmAnd protocol ?
Not sure what you mean by same logic, but OsmAnd is not a good example.
Hi Anton,
Below are the details about protocol, please help me to add this device on server.

0 Tamper ValuePlease copy above details in any file, seems formatting is not working,I was trying to use below code to encode and decode
pipeline.addLast("frameDecoder", new CharacterDelimiterFrameDecoder(1024, "\r\n", "\n", ";"));
pipeline.addLast("stringEncoder", new StringEncoder());
pipeline.addLast("stringDecoder", new StringDecoder());
pipeline.addLast("objectEncoder", new Gps103ProtocolEncoder());
pipeline.addLast("objectDecoder", new Gps103ProtocolDecoder(Gps103Protocol.this));
Is there necessary to write objectEncoder for above string ?
Please provide proper full documentation.
Hi Anton,
I have added new protocol for above device at port 5105.But when I see log, port is not open.
I also added protocol in traccar.xml. Is there any other configuration required ?
No configuration is needed if you created all required classes, mainly Protocol class.
Hi Anton,
I have created all required classes like protocol and decoder and added port no in traccar.xml. but when I check on console
-- sudo netstat -ntlp | grep :5105
No any port is open or listening
but when I check for others like
-- sudo netstat -ntlp | grep :5103
It is showing like below
tcp6 0 0 :::5103 :::* LISTEN 22081/java
Why 5105 is not listening ?
Show me your code on GitHub or somewhere, but please don't paste the whole code here.
Protocol

serverList.add(new TrackerServer(new ServerBootstrap(), this.getName()) {

pipeline.addLast("stringDecoder", new StringDecoder());

}

I explicitly asked you not to post code here and you posted it here.
I need to see all the modifications that you did, including config file. PLEASE DON'T POST CODE HERE.
Hi Anton,
Really sorry,Please delete above post if possible.
Please have a look github link.

I added <entry key='trackingpath.port'>5128</entry> in traccar.xml
In the "TrackingpathProtocol" class you have uppercase "Trackingpath", but in the config you use lowercase "trackingpath".
r u talking about this super("Trackingpath"); ? Apart from this is everything ok ?
Hi Anton,
I have purchased a new GPS device from a local vendor, when I connected to Traccar server, getting data in ASCII format.
How can I add this in traccar server.
