Coban 306A?

Hi,
is this device supported? I tried connecting it via port 5002 and get:

2015-05-04 11:09:18 DEBUG: [071592D2: 5002 <- 89.15.239.229] - HEX: 3836353332383032313035363335323b

Thanks.

Yes, it uses GPS103 protocol. Port 5001 in Traccar. Make sure you configure device to report location (you need to send some special command).

Thanks. Now I get

2015-05-04 13:54:15 DEBUG: [BF79FE34: 5001 <- 89.204.138.96] - HEX: 23232c696d65693a3836353332383032313035363335322c413b
2015-05-04 13:54:15 DEBUG: [BF79FE34: 5001 -> 89.204.138.96] - HEX: 4c4f4144
2015-05-04 13:54:57 DEBUG: [BF79FE34: 5001 <- 89.204.138.96] - HEX: 3836353332383032313035363335323b
2015-05-04 13:54:57 DEBUG: [BF79FE34: 5001 -> 89.204.138.96] - HEX: 4f4e

So it seems the device and server are communicating properly.
Do you know by any chance which command to send? From the (poor) documentation it seems that I have enabled sending location already...

One more question: can traccar track ODO on top of GPS values as well with this device?

Try command from this thread:
https://github.com/tananaev/traccar/issues/529

As for odometer, it might be available if your device reports it.

Thanks. GPS location works. Just can't see ODO. Is it possible that the Coban 306a only supports ODO via SMS (and not via GPRS)?

Can you provide HEX message from tracker-server.log and the ODO value you are expecting. I will check if it's there.

It seems that the Coban 306a does not tract ODO values. Just GPS.
Do you know of any OBD-based tracker which reports ODO?

You can find list of OBD supported devices here:
https://www.traccar.org/forums/topic/supported-odb-gps-trackers/

I'm not sure which ones of them support odometer reporting though.

I want to write C# code that will communicate from my PC running a TCPIP server to the Coban 306A tracker.

Where can I find the documentation for the GPS103 protocol?

You can request the protocol documentation from Coban or just download it from the protocol page instead :-)

The Coban 306A does support odometer reading, but only with a limited amount of cars. It's basically hit or miss. (And more 'miss' than 'hit' really.) Want something more reliable? Go with Teltonika. They have a feature called 'virtual odometer' that will always work, because what it basically does is keep track of the traveled distance internally, so without having to depend on the OBD implementation. The only time this won't work, is when the tracker doesn't have GPS reception. But this would only occur in a parking garage for instance.
