<![CDATA[Not Serial Com in OpenIMU 335RI]]>Hello

I have been trying to connect to my development board of the IMU335RI via the RS232 connector. I used a ST-LINK v2 to upload the OpenIMU355RI/VG example from the Visual Studio Aceinna extension.
Then I run the OpenIMU server app to connect with the Aceinna Navigation Studio. I get connected to the Studio but not with the IMU, thus there is no data on the screen.

Aceinna NAVStudio

OpenIMUserver

I'm using a FT232R module from SparkFun to make the rs232 to USB conversion. I also set these parameters on the COM port:

COM parameters

Is there anything I'm missing? Should I modify a code line before upload the firmware to the IMU?

This is the link : https://github.com/Aceinna/python-openimu/releases/tag/v2.6.1
If you just want to get data , you can also use the Naview , I have posted a Naview 3.5.12 file in the forum before, you can search it

In addition, when NAVIEW is connected, is the indicator line at the bottom l green or red? If it is green, you can set the packet sending rate in the
unit configuration of configuration
