H02 and UDP

Piorun6 years ago

My tracer works fine over TCP, but it can't communicate over UDP. Traccar see the packets from device so network configuration is fine.
I use v3.15 (I hope the hotfix 'Enable UDP for H02 protocol' is included).

Communication over TCP

Are you using latest release? I would need full HEX samples to check the issue.

Last four digits in IMEI are masked ... please delete my message after reading.

There was a server issue, but I have fixed it now.

Thank you for prompt response :)
Could you provide the compiled version of Traccar (just JAR) - I don't have the Java SDK installed.

Anton Tananaev6 years ago

Unfortunately I can't, but you can wait for next official release which should be fairly soon.

One more question to the hotfix "Handle H02 message new line ":

My tracker doesn't respond to any commands.
Is it possible to add EOL (\0x0d,\0x0a) to the command sent from Traccar to the device? (or define command as a hex string)

Device -> Traccar (EOL at the end)

0000   2a 48 51 2c 38 36 35 32 30 35 30 33 31 31 31 31  *HQ,865205031111

Well, it works for most devices, so we can't really break existing ones.

h02 works over UDP on build 3.16, THX!
