With my IMU just sitting motionless on the table I get really bad acceleration values. See screenshot. Any have any ideas how this can be rectified? Thanks!

Reading the docs on the 335RI IMU it seems you can set the CAN address and Baud Rate. Can this be done over a RS-232 connection with Nav View? If so could you provide steps on how to do that or direction.

Appreciate any and all help and your time 🙂

How can I configure the IMU with serial communucation commands?

Using the provided software, we can read data only when both the ST-Link debugger and the RS-232 are connected. However, we cannot read data when only the RS-232 is connected.

We need to be able to request data using our own software by sending commands via RS-232, without connecting the ST-Link. Why does it not respond to commands if the ST-Link is not connected? Do we have to do some prior configuration?

Is there a document somewhere where the frames are presented as in your screenshot? So an id, a frame in hex and a description of what the frame does? In the documentation, I only found a description of frames in the J1939 standard, which in my case requires converting the standards.

But I have a question on Magnetic field.![alt text](fdb53ad9-7000-42a6-a11b-f4eac12e0c6b-image.png image url)

How can I calculate this packet?
And why Magnetic Field Z over the range even though range is -8 to 8 Gauss?

I am only interested in the fixed baud mode if the sensor does start to transmit without any start frame sent via can bus. Is this possible? Like when I connect the sensor to the powersupply, it should start sending on the fixed baud rate.

I have exactly the same problem, but I already tried the server app and the green messages didn't show up. I have connected the IMU to my computer using the RS232 connector through a USB-RS232 converter, the computer detects the COM, but nothing happened on the server app.

I programed the IMU with the openIMU335IR/VG sample using the ACEINNA extension for visual studio code.

Is there anything else I must do to establish communication with the IMU and the navigation app?

We are changing a packet type of CAN message.
So, we download the custom IMU example file of OpenIMU335RI/VG using the platformIO of VS code.

However, we cannot build the modified project. Because there is no include folder ( below figure ) .

Could you let me know how to import include folder for OpenIMU335RI device???
