B4J Question Jserial bug ????

[Pietro Pancino]

Hi all,

It's a long time that I am using Jserial lib. It use to work very well since today on Dmx apps, communication with Hardware and so one...

All codes written before today don't work anymore. In fact after opening a com port the application crash. (I put the error log file into the zip...)

The most strange, is that when I launch the app under B4J in release mode, the apps work, I can open com port with no problem an send and receive data.
But when I launch it directly from object folder, the apps crach and the error log tel me that there is somethong wrong "withjssc.SerialNativeInterface.openPort(Ljava/lang/String;Z)J+0".

Since I'am not a Java specialist, I'm stuck in my ignorance :-((((
If any one can help a poor com port user!

On more things, coms port work perfectly on Windows Terminal.

Maybe it's a java update or

You are probably using different versions of Java.

Are you using jSerial v1.31: https://www.b4x.com/android/forum/threads/jserial-library.34762/ ?

Hi Erel,
My Jserial version is 1.05, so I am going to install the 1.31 and I'll tell you the result.
I am going to test the apps on different computer.
I Tell you soon !
