Issues running application on Ubuntu/R-Pi

[beischel]

Hello folks,

I have the P25RX application running on my R-Pi using Ubuntu Desktop. However, the application cannot seem to find the receiver. Just says discovering device. Please wait. Any insight as to what I need to do to get the application to find the unit?

Second, not the greatest at Linux. How do I make it so that clicking on the application will start the application? Right now I am staring from the command line.

Thanks for any assistance!

Maybe this will help. Just noticed this in the terminal window. It is constantly doing this andkeeps scrolling.

"found device on : ttyAMA0 USB-Based Serial Port USB-Based Serial Port USB-Based Serial Port closed
attempting to close locked port BlueTail-P1"

Try adding this line to /etc/udev/rules.d/50-myusb.devices
KERNEL=="ttyAMA[0-9]*",MODE="0666"

OK, the 50-myusb.devices file did not exist so I created that file in the rules.d directory. Copied and pasted the line, saved the file, rebooted and still the application cannot discover the P25RX.
Anything else that I can try?

before you start the BTConfig software try this command to change the permissions of the serial port:
sudo chmod 666 /dev/ttyAMA0

Still not working.....was hoping others with Ubuntu on a Raspberry Pi would weigh in on this.

Right now I am staring from the command line.

Try adding sudo to your command line to start app.

I do not have a rpi.
Sounds like unix permissions issue.

That would work too. Run as root.
sudo java -jar BTConfig-xxx.exe

Running with sudo worked! Thanks Folks!

Now that I know the issue, I will dig into further to change the permissions.

Good deal. Once you get it all running please share how well your rpi setup works with the p25rx rig. Tnx
