java error starting bt747 2.1.3

Starting bt747 I see following exception from java:

RXTX on Suse 12.2


I just upgraded myself from Suse 11.4 to Suse 12.2.

When installing BT747 I obtained an error message that RXTX-Java is missing.

Does anybody know where to find that Java component.

Thanks in advance.

Crash when connecting - suggestion

I had a report recently about BT747 crashing when trying to make a connection on a Intel Core 2 Duo running "Debian GNU/Linux unstable (sid), package 6b14-1.5~pre1-3".

BT747 1.68.5 was using RxTx 2.1.7 - the currently stable version of RxTx and the crash reported:
# Problematic frame:
# C [librxtxSerial.so+0x6462] read_byte_array+0x52


The process can be split in three big steps:

  1. Install the serial link driver
  2. Prepare to get the serial link to work (RxTx driver, only once)
  3. Install the application

In more detail, it goes like this:

  1. Usually the manufacturer did not care about MacOS, so you need to get the serial driver yourself from http://www.silabs.com (CP2102 VCP drivers).

    You do not need that driver if you are using bluetooth.


As on all platforms, the following steps are needed:

  1. Install the serial link driver (for USB, to be done only once on a computer)
  2. Install the application
  3. Get the serial link to work (RxTx driver)

In more detail, it goes like this:

  1. Usually the USB driver comes on a CD with your device. If not, you can probably get them from http://www.silabs.com (CP2102 VCP drivers)
  2. Installing the application as indicated elsewhere
