Anyone already used it? for reading modbus.

i got this insterseting modbus library in jar file, maybe some one
could wrap it to jTCPSocketClient.

You can get from here: (opendrive.com)

https://od.lk/f/Ml8xOTc0OTIwNzNf

a complete tutorial (from image1 to image34) how to add an "online"
library to LAMW [new jComponent]!!!

However the "datalogic"  APIs tested in LAMW code returned nothing
(nil)...

In fact the library source code pointed by Android Studio is clearly
returning null in several APIs....

Edited:

1) Added to LAMW "Docs": "How_to_add_an_online_library_to_LAMW.txt"

2) I will create a initial jModbus component,  so we can try improve
it!

Ok.

But don't give up!  try find the error! "Android Studio" can help you!

(you "net" is ok?  you have a IP/Port for  Modbus server?)
