How do I use this driver for MTI-30?

[jediofgever]

Hi,
I have a MTI-30 model. When I run the driver it crashes with

[ERROR] [1628158672.132779485] [xsens_mti_node]: No MTi device found.

but lsusb does show this ;

Bus 001 Device 007: ID 2639:0003 Xsens MTi-30 AHRS

How can I use this driver for my sensor ?

Ahh OK.
Needed to do;

sudo chmod 777 /dev/ttyUSB0

it will be nice if you put a notice on Readme about that. So other people notice it.

@jediofgever This issue has been documented in the readme. Take a look at the following point in the troubleshooting section. The correct way to handle this issue is by adding the user to dialout group. Doing a chmod, sometimes resets the permissions when the device is disconnected and connected back.

- The device is recognized, but I cannot ever access the device -

    Make sure you are in the correct group (often dialout or uucp) in order to
    access the device. You can test this with

        $ ls -l /dev/ttyUSB0
        crw-rw---- 1 root dialout 188, 0 May  6 16:21 /dev/ttyUSB0
        $ groups
        dialout audio video usb users plugdev

    If you aren't in the correct group, you can fix this in two ways.

    1. Add yourself to the correct group
        You can add yourself to it by using your distributions user management
        tool, or call

            $ sudo usermod -G dialout -a $USER

        Be sure to replace dialout with the actual group name if it is
        different. After adding yourself to the group, either relogin to your
        user, or call

            $ newgrp dialout

        to add the current terminal session to the group.

    2. Use udev rules
        Alternatively, put the following rule into /etc/udev/rules.d/99-custom.rules

            SUBSYSTEM=="tty", ATTRS{idVendor}=="2639", ACTION=="add", GROUP="$GROUP", MODE="0660"

        Change $GROUP into your desired group (e.g. adm, plugdev, or usb).

Many thanks for the additional info. I will switch to that method then.
