Data usage (bandwidth) GT06n

jaimzj9 years ago

Dear Anton,

Just wondering if you might have some input on this.

I was wondering how much (data/bandwidth does Gt06n device or any other tracking device for that matter) use per update.

Assuming a device gt06n frequency of update is set to 5 seconds, What is the payload/data size of each update.

And how much data would be consumed by the device/gsm network over a period of lets say 1 hour.

Any information on this?

GT06 location update message is usually less than 50 bytes long, but there is also TCP protocol overhead (20 bytes header plus connection handshake messages and acknowledgements).

So, if we take estimate of 100 bytes per message including overhead, it would be 72 KiB per hour (message every 5 seconds). Note that it's only a very rough theoretical estimate.

Dear Anton.
i used your parser traccar-server to communicate with a device installed in taxi this device use GT06 protocol.My problem is that traccar use more than 100 MO to communicate between device and server in 13 days is that normal ?

It doesn't sounds normal. Most likely you have many reconnects and your SIM provider has a minimum unit of data if charges you for. For example, some providers always round data up to next 100KB for each connection.

Is there a way to monitor the status of Traccar (runniong/stopped)? It seems that it's running many threads? how to detect the main thread?

Just use standard system tools to check if the process is running. It has many threads, but there is no main one.

i added this line in traccar.cfg <entry key='gt06.resetDelay'>60</entry> do u think that this is the problem that make my device do soo many connections ? if yes how i can correct this bug .
thanks for your help .

Yes, that might be a problem, but real problem is your SIM card plan. For tracking devices you shouldn't be using a SIM card with minimum charge per connection.

Ok, thank you for your help i will check this.
