B4R Question B4R IDE "Connect" button

[peacemaker]

Hi, @Erel

1) About "Connect" button of B4R IDE: why does it not always work ? Sometimes it does not connect to the COM-port, but the same time - Arduino's Monitor - always connected when opened.
Another COM-port terminal is also always connected, and if the port speed is chosen wrong - it's visible non-readable output from MCU at each reset button pressing.

Spoiler: Screenshot

2) I have found a second time (first) a ESP32 board that works OK in Arduino, but no log output to B4R log after flashing, but Arduino's monitor and Terminal show the log OK.

"Waiting for a Classic BT client connection..." is my text from the B4R sketch, but one time after flashing i have caught such B4R log, after it the log is again empty:

.....
TRACE StatusLogger XmlConfiguration stopped 2 remaining Appenders.
TRACE StatusLogger XmlConfiguration cleaning Appenders from 2 LoggerConfigs.
DEBUG StatusLogger Stopped XmlConfiguration[location=jar:file:/C:/Program%20Files%20(x86)/Arduino/lib/pde.jar!/log4j2.xml] OK
DEBUG StatusLogger Stopped LoggerContext[name=1e6f5c3, org.apache.logging.log4j.core.LoggerContext@196c360] with status true
********************* PROGRAM STARTING ****************
#3B�4�#����������ting for a Classic BT client connection...

... and the hw reset button does not show any log more. But if to try to re-flash - B4R's log is just empty after "****** PROGRAM STARTING *****".

How to understand what the problem can be ? I guess, something may be in IDE connection code.

p.s. the ESP32 board are fully re-soldered point-by-point - nothing changed. And compared to another board example - fully identical components. But second board works OK in any terminal, including B4R's IDE.

B4R calls a B4J program, similar to the external serial connector, to connect to the port and read the logs.

If you want to debug this issue then switch to the external serial connector and try to understand what causes the connection to fail.
