Hi.

I'm interested in get one european SIM roaming, and the question is:

Is possible know the ammount of daily traffic in megabytes, if the configuration sent the possition every 15 mins or aprox?

Is possible implement one traffic reduction for this "roamers" when the android device is stoped or in the night time?

Regards.

My phone send every second new position, even if I change 60 seconds.

There is a big battery drain with the new version 2.1 compared to 1.5

Get location from both GPS and Network providers.

if high interval is choosen, like 10 minute, app starts and will send first data after ten minutes, it would be more practical to send data after first connection after startup and then wait 10 minutes

I saw several identifiers on configuration file page, is it t55.enable how I can give traccar client support on traccar server?
thanks

Hi there,

do you plan to include some more data fields in the data protocol of the app?

• battery state
• external charging state
• csq data
• cell data

And by the way, do you plan or do you consider to include something like two way communication? Maybe server sends "Hi user" and app shows that message on screen. Something like that.

Best regards from germany
Boris

my-GPS.org

Add option to check accelerometer sensor, and if there is no motion stop sending GPS data.

Hi,

Can I run the Traccar on the shared hosting server?

What requirement is needed to run the Traccar Server on shared hosting?

I was wondering how to use the traccar server. I have already created an account. I added the imeii # where it says unique identifier. How do I get the tracker to send information to the server?
Device: TK103
Thanks

Hi Anton,

I am developing my own Android Client for Traccar. Right now i have the current location latitude and longitude values which i derived using my own algorithm.

now i want to know the format for sending these values to the traccar server and also please tell me about the format for sending the login message (IMEI number) and connection(address,port).

Thank you very much...

Hi anton, I was testing your program and it seems to have a coordinates issue, we test the client on several devices using your client and google maps, when in google maps was displayed a location, it was really close to the real location but at the same time when we check the location given by your client, it was really far away from the real location.
So, maybe something is wrong with the coordinates.
thanks

Hello, I'm a spanish, follower of Traccar. I think that you do a great job.

I attach a translation to spanish of the messages of the client.

If you think that it is good, please considerate incluiding it in the next version.

I want to use Traccar as a 'Personal Tracker' and I will focus in this path.

Thank's very much.

Would be nice if the client can save its coordinates locally when there is no network connectivity and send them all at once when the connectivity is re-established. Most (or may be all of) the phones nowadays doesn't provide network connectivity when phone call is in progress. This feature would be very handy for people who often make long hands-free call while driving and/or there is no cellular coverage in the area.
This feature can be also extended to provide fully offline tracking capabilities.

I have tried on different devices but not all the devices are located by the server.

A simple example I tried to setup a local sever on wi-fi and tried to locate device
Devices establish the connection with server but Position are not sent to the server, Position table is empty.

Android version is 2.3.8

Frequency set for 5sec

Log:

2013-06-24 14:24:40 org.traccar.BasePipelineFactory$StandardLoggingHandler.log FINE: [5005 <- 10.0.1.97] - (HEX: 24504749442c3335343435373035303738343038352a30310d0a), after this there is no log.

Please let me know what would be the reason for this.

First of all-AWESOME!- work on this suite of applications. I am having an issue with the Android clients. When I was using the traccar web server the traccar Android client was working and reporting a location. When I changed the configuration to work with OpenGTS I now get the following errors in the log:

2013-01-25 22:32:21 org.traccar.protocol.T55ProtocolDecoder.decode WARNING: Unknown device - 012861000242397

I have the device added in OpenGTS but no events are ever added. After the initial error this is what shows up in the log:

Hi ... I am using demo.traccar.org as the collection server. My user ID is sibarhm and my IMEI is 358490047475380. I set the interval every 15 secs in the client, however when I see the data in web it is recorded ever sec. I read the previous close issue and it mentioned something related to next version of client. I do not see version number in the client (under About). Any clue?

I wuold like to request to add a feature/enhancement in the Traccar Android client main page so that I will know whether the last upload of the GPS device to the server is successful:

Show last successful updated(upload) time in Traccar Android client.

This is just a copy from Traccar issue:

Hello,
I'm using traccar client on Samsung Galaxy Nexus. The client is crashing every time when another app which is using GPS is being launched. (iGo, Google Maps Navigation, Sygic, Facebook etc, sometimes even Skype affect it).
When the app crash, a message "Unfortunately, Traccar Client has stopped." is being displayed.When opening the app again, its "Service status" remains "Running" and "Connection status" is Connected, however no messages are sent to the server.

Tested under Android 4.1.1, 4.1.2 and 4.2 - stock firmware from Google and 4.1.1 - stock firmware from Samsung.

PS: can i somehow make the app to start automatically when the OS is rebooted without using external app for this?

Do not send coordinates if speed is lower than N km/h.

With the previous versions (prior v2), when I kill the app using android's built-in task manager, it actually stops until I start it again, which is bad of course.
This was fixed with version 2.1, zygote is re-starting the service as long as the service button is ON. However this doesn't work every time. Sometimes the service is being restarted in about 5 seconds, sometime longer up to a minute, but sometimes it is not being restarted at all.
I couldn't find any reason for this, it looks completely random to me.
Thanks.

I turned source code of android client into apk. Its working fine, even showing location update. I am using default settings.

why doesnt it show position on map?

In service onCreate() super method should be called.

Hello,
I'm using traccar client with traccar server. The speed shown at the web interface is not correct. While driving at about 50-60km/h, speed shown at the web interface is about 15knots (~28km/h).
The server is showing the exact speed in knots received from the client, this is why I suspect client bug.

Hi,

I have downloaded the Traccar CLient into a tablet device.
Had run the app and enter relevant info into the http://localhost:8082/
But nothing seems happen. I only see a map with the device info on the left of the screen.

I use the port 5005 as mentioned in http://www.traccar.org/client/

and looked at the STATUS page of the client app.. It always shows Connection Failed.

connection.close() probably crashed

Do not send coordinates if distance between last and current position is shorter than N meters.

Move string that not supposed to be translated to separate file.

Show sticky notification to show user when Traccar Client service is running.

The client is installed in a Sony Xperia U device.
Where the device lost the GPS signal it search for a long time the signal and passed an indeterminate time, it blocks.

The conection with server is working but never ask to the GPS again for the location

For restablish the conection with the GPS, I have to stop the service, stop the Android GPS conection, and start them again.

This error may avoid if :

a) disconnect automatically the GPS when the device is no-moving
or
b) switch to the 'Network provider' when the device is no-moving or not have GPS coverage

In the other hand, you may implement a 'system' to check if service need to be restarted.

Thank's a lot.

Do not send coordinates if accuracy is above N meters.

Autostart service at boot time feature.
