<![CDATA[RS-232 communication]]>We have acquired an evaluation kit of OpenIMU 335RI. 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?
