target is not responding, retrying

[IVent.1]

I have a program with various tasks, in one of these I send a request and, after that, I wait for a response, so I have a cycle like this

SendRequest();
do
{
WaitResponse();
DelayMillisecondS(200);
}while (Timerisnotexpired());

the Problem is that the answer takes time to be given and I receive messages like this "Target is not responding, retrying...", sometimes I receive a sequence of this messages and the debug connection terminates. Probably, the clock to the stlink fails, but I don't know how to make up with this. I have lowered the frequency of swd interface and I have enabled "Suspend watchdog counters while halted", but the problem remains.

Any help would be appreciated.

Thank you

where, exactly, do you get that message? STM32cCubeIDE? other? version?

Does WaitResponse() put your target to sleep?

No, WaitResponse() only check the uart for some response.

I receive that message in the Console Window.

Using Stm32CubeIDe 1.16.0
