XEXUM emulation UDP : no frame received

philippe de LUSSY 7 years ago

Hello

we wish to use Traccar to display / follow GPS devices whcih we are building (no GSM based) . We have emulated Xexun protocol on UDP 5006 / broadcast .
The frames are well received on the server, but not seen on traccar (no trace in the log).

Coudl you indicate if Xexun UDP is supported , and more generally frame reception via broadcast ?

Thanks in advance .

Best regards

Xexun is a TCP protocol, so UDP is not supported for port 5006.

Hello

OK , do you have a list of device / protocol, supported by Traccar in UDP ?

No, I don't have a list, but you can easily check using netstat or other similar tool.

I think there is a misunderstanding : we wish to "pick" a protocol supported by Traccar, working in UDP, and then "mimic" it in our devices.
Said otherwise we expect to use traccar, at this stage for a pilot, to graph the move of a dozen of GPS sensors, custom build.
as such XEXUN protocol was providing almost the exact frame we need ( coordinates, altitude, precision, sv, battery, identifier as imei, and more as network related fields) .
hence my question on which other GPS sensors supported by Traccard running in UDP : as H02, Atrack, TK103, GPS103 ( found by searching the forum)
any help will be appreciated.

I don't think there is any misunderstanding. You can find out which protocols use UDP by using netstat. Why do you think there is a misunderstanding?

a) don't see UDP socket opened , perhaps I do not wait a sufficent long time.
b) at this stage , we are developping the sensor, so there is no traffic to sniff ! this is teh otherway around : we are building the solution, hence our questions on which protocol(s) we can mimic.

Sorry if it was not clear enough.

a) You should see open ports if server is running.
b) I never said that you should sniff any traffic.

Anton

got it , viat netstat -p udp. ( and it seems there are a bunch of it, only feww as Xexun are missing !)

we will have a look at that .

By the way , do you have a mean to enable Xexun on UDP ( and keep it on TCP as it is its standard behavior ) ?

Hello
So I have extracte on my server the list of opened ports , TCP and UDP, and cross-check to you protocols list. ( Device;GPS-Protocol;Port UDP;TCP)

If interested let me know where to upload it.

Strangely , ports 5181-5182-5183-5184 appears in you list but are not opened ( no listening) , there are the latest ones.

do you have a mean to enable Xexun on UDP ( and keep it on TCP as it is its standard behavior ) ? ( as for example GL200 which is both UDP and TCP) ?
