Getting "timeout reached" error on gx3-45

[limjizhengshawn]

Hi all,

I am getting a timeout reached error whenever i try to run the get_id or the imu_node. I am currently using the Microstrain GX3-45 using the factory default settings.

Linux: Ubuntu 14.04 LTS
Device: Microstrain gx3-45
ROS: Indigo

Below is the error I'm getting..

get_id:

terminate called after throwing an instance of 'microstrain_3dmgx2_imu::TimeoutException'
what(): timeout reached (in microstrain_3dmgx2_imu::IMU:read_with_timeout)
Aborted (core dumped)

imu_node:

Exception thrown while starting IMU. This sometimes happens if you are not connected to an IMU or if another process is trying to access the IMU port. You may try 'lsof|grep /dev/ttyUSB0' to see if other processes have the port open. timeout reached (in microstrain_3dmgx2_imu::IMU:read_with_timeout) You may find further details at http://www.ros.org/wiki/microstrain_3dmgx2_imu/Troubleshooting

---

Using the lsof|grep /dev/ttyUSB0, only imu_node shows when i run the package. When the package is not running, the command returns nothing.

When i connect the imu to windows and use the MIP software, the imu works fine and it is able to get data.

I am wondering if there is anything I'm doing wrong?

As far as I know the GX3-45 is not supported by this node. As we also have this unit in our lab I wrote alternative simple driver for it, see https://github.com/ZdenekM/microstrain_3dm_gx3_45.

Hi Zedenek,

Thanks for your quick reply.
I've tried using that package too and the device succeeds in pinging and
setting to idle.. however it gets stuck in the devStatus function. That is
the part where the timeout occurs.. is it because of some setting error?
