Pixhawk 6c : monitor and tune error when using telemtry

I'm currently using matalb2024a and using pixhak6c.

I want to control without using Radio Control, so I planned to use telemetry radio.

When monitor and tune simulation is started using USB (COM11), it works normally, but it does not connect when telemetry (/dev/ty/S5, COM3) is used.

Error: External Mode Open Protocol Connect command fails

Cause:

Could not connect to target application: XCP internal error: timeout expired, in response to XCP CONNECT command

In the Qgroundcontrol parameter setting, MAV_CONFIG_0 was set to disabled.

Is there a solution?

Can you try changing the baud rate of /dev/ttyS5 to 57600 in the configuration settings and try External mode again?
