rosserial problem with 2 publishers

edit

HI guys!

I am working on a project in which I created my own package. So far all is working fine. I have 2 messages to publish with my chipkit MAX32 (Arduino Mega, compatible).

I am able to publish correctly on 1 of them called "AGVStatus". The second one it the "RangeArray" message. I have the packge compiled with no errors.

In my code I include the .h files

#include <ros.h>
#include <agv_ip/AgvStatus.h>
#include <agv_ip/RangeArray.h>

And I declare both the same way:

agv_ip::AgvStatus estado;
ros::Publisher Status("AGVipStatus", &estado);
agv_ip::RangeArray range;
ros::Publisher Ranges("AGVipRanges", &range);

Everyhting ok when uploading to the board.

This is what I get when running only the Status message:

[INFO] [WallTime: 1447935106.608875] ROS Serial Python Node

[INFO] [WallTime: 1447935108.768334] Setup publisher on AGVipleiriaStatus [agv_ipleiria/AgvStatus]

And this when running with both:

(Ros indigo with Kubuntu 14.04)

Can You help me here with some tips?
