I run the roslaunch imu.launch, then it works good, despite it shows a warning message periodically "Something bad when reading". This warning suggests that some readings of imu are lost.
But the problem is not the warning. After 2 hours, more or less, the node crashes, raising an exception:
"IndexError: bytearray index out of range" in line 224 of bosch_imu_node.py.

I have tested it more than 3 times and it still with the same behavior. I also have tested with another imu board that has the same model, but nothing has changed.

I am using an Adafruit board with bno055 connected to an UART-USB converter (FTDI).

lsusb command shows information about the FDTI:
Bus 001 Device 029: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

The FTDI is connected to one USB port of Intel NUC with Ubuntu 18.04.4 LTS bionic and ROS melodic.

Is there a workaround for this problem?

Thanks in advance.

Hi,
I have interfaced the IMU with the arduino and can use the adafruit library. I do not understand how to then connect this with ROS ? Can you help me with this. There are no information on the ros wiki page. I think its not been updated for a long time.
Thanks

Alex

According to Adafruit's site

Once the device is calibrated, the calibration data will be kept until the BNO is powered off.
The BNO doesn't contain any internal EEPROM, though, so you will need to perform a new calibration every time the device starts up, or manually restore previous calibration values yourself.

Therefore it would be convenient to have an option to save calibration data and re-load it upon startup.

I have begun working on this functionality and will make a pull request when complete.

To whom it may concern,

I am able to launch the node but immediately after it tells that the process closes by itself. Any idea of the issue?

Hi, I have this BNO055 attached tu a usb: http://www.mouser.com/ds/2/783/bosch_BST-BNO055-AN009-00%20USB%20stick%20user%20guide-890618.pdf
the problem is that I do not get it to wokr with your driver, i sends data but do not receive anything, I keep getting these errors:
[ERROR] [WallTime: 1487591149.357895] Incorrect Bosh IMU device response.
[ERROR] [WallTime: 1487591149.358092] Device ID is incorrect. Shutdown.

do you know why could it be?

Thanks a lot for your work!

I have the BNO055 in the adafruit breakout board, like this tutorial: https://learn.adafruit.com/bno055-absolute-orientation-sensor-with-raspberry-pi-and-beaglebone-black/software

can I simply swap the parameter "port" from '/dev/ttyUSB0' to '/dev/ttyAMA0' ?

thank you in advance.

according to script
frequency = rospy.get_param('frequency', 100)
