RE: Freerunner, Jalimo, rxtx, GPS

[Juan Lucas Dominguez Rubio]

Hello, my goal is not just accessing the GPS device. I'm trying to run on 
Openmoko a certain java application that uses librxtx to access the GPS, and 
librxtx happens to be in the Openmoko-Jalimo repository. I'm not asking for the 
moon

Anybody has used this librxtx?

http://jalimo.evolvis.org/repository/openmoko/

The person who uploaded it, perhaps?

Regards,
Juan Lucas

I have no idea at all, but a question: have you tried using FSO and it's
dbus API for GPS/positional services?

You don't say which distro you are trying this on, but my guess is
that you are fighting with gpsd or frameworkd for access to the GPS
serial port. You probably should be talking to gpsd/ogpsd or via dbus
to the framework, rather than directly to the serial port.

Freerunner, Jalimo, rxtx, GPS

[Juan Lucas Dominguez Rubio]

Dear list,

I am trying to use librxtx to access the GPS device in my FreeRunner through 
the /dev/ttySAC1 serial port. I have done this:

opkg install librxtx-java
opkg install librxtx-jni

In the classpath of my little java app I have added RXTXcomm.jar and tried to 
execute this code without success. No ports are discovered (with the GPS on and 
off), and if I try to access a port called /dev/ttySAC1, it says it does not 
exist. What am I doing wrong?

=
  static void listPorts()
{
java.util.Enumeration portEnum = 
CommPortIdentifier.getPortIdentifiers();
while ( portEnum.hasMoreElements() ) 
{
CommPortIdentifier portIdentifier = (CommPortIdentifier) 
portEnum.nextElement();
System.out.println(portIdentifier.getName()  +  " - " +  
getPortTypeName(portIdentifier.getPortType()) );
}
}

static String getPortTypeName ( int portType )
{
switch ( portType )
{
case CommPortIdentifier.PORT_I2C:
return "I2C";
case CommPortIdentifier.PORT_PARALLEL:
return "Parallel";
case CommPortIdentifier.PORT_RAW:
return "Raw";
case CommPortIdentifier.PORT_RS485:
return "RS485";
case CommPortIdentifier.PORT_SERIAL:
return "Serial";
default:
return "unknown type";
}
}
=

Juan Lucas
