Hi Bryan,

In version venus-gps-0.1.0.zip the file ‘cbuffer.c’ has not updated changes.

Are you sure it’s the latest version?

[Miguel Ángel]

Hi Bryan,

Thanks for your support.

I have the source file and I made the changes directly. I downloaded the source files (venus-gps-0.0.2.zip) by http://git.multitech.net/cgi-bin/cgit.cgi/venus-gps.git/

In that case, what would you propose?

[Miguel Ángel]

Hi Bryan!

I think I’ve found some bug.

I run the application venus-gps (venus-gps –mode server –port 8888 –gga 30 –gsa 0 –gsv 30 –gll 0 –rmc 5 –vtg 0) and the result is the following:

Hi Bryan! It works ok, thanks a lot for your support!

[Miguel Ángel]

Hi Bryan,

I have made ​​the changes.

Now I get an error only in the frame number 8. See the following image:

https://www.dropbox.com/s/252kbbf1c8amd8w/captura5.png

Can you see that disappears the digit 6 in frame number 8? This error appear only in frame number 8. If I restart the application reappears the error. This error is not very serious because I use the CRC to check error frames.

Is it an error from “HW gps” or “SW venus-gps”? It can be corrected?

Thanks a lot

Can anyone check if the same thing happens?

[Miguel Ángel]

I’ve been tested on another MTCDP-H4-GP with version of CoreCDP is 1.1.1.

I have run the original application venus-gps (venus-gps –mode server –port 8888 –gga 0 –gsa 0 –gsv 0 –gll 0 –rmc 5 –vtg 0) and the result is the following:

In this case do not appear zda frames but I receive incomplete messages.

The product/model is MTCDP-H5-GP and the version of CoreCDP is 2.2.2.

I made one more test. I have run the original application venus-gps (venus-gps –mode server –port 8888 –gga 0 –gsa 0 –gsv 0 –gll 0 –rmc 5 –vtg 0) and the result is the following:

Hi!

I have a problem with cron. I modified the file (/etc/cron/crontabs/root) by adding a call to a script. Unfortunately I did not run correctly call to cron. Does anyone knows what could it be?

Did anyone tried it?

[Miguel Ángel]

Finally I know find the port. Now every time you reboot the machine the port is different. Is there any way to fix the port?
