Raspberry Pi

[m6oba]

I wonder if anyone can help me with trying to use Pocket Rx/Tx with a Raspberry Pi and a Yaesu 897.

I'm using jAReCmini 0.8.1 and Pocket Rx/Tx v0.8.1-1 ( also tried -2 ).

When I start jAReCmini 0.8.1 SSH I get:

Code: Select all

pi@raspberrypi:~/Downloads $ sudo java -jar jarecmini.jar
jAReC mini version 0.8.1

Listening for connections on 192.168.0.78:4443

But when I try to connect with Pocket Rx/Tx I get:

Code: Select all

Cpi@raspberrypi:~/Downloads $ sudo java -jar jarecmini.jar
jAReC mini version 0.8.1

Listening for connections on 192.168.0.78:4443

Here is my jsn.cfg file:

Code: Select all

#Wed Sep 02 14:29:27 EEST 2015
bUseAuthentication=false
sHSecret=2743C71E3828333B277A8FE65050595BF13DD669
sBaudrate=38400
bUseAudio=false
bAutostart=true
sCOMport=/dev/ttyUSB0
nwPort=4443
iRecInterface=5
iPlayInterface=0

I am not trying to stream audio via Pocket Rx/Tx, I have the audio streamed my home already via a Sonos multiroom speaker set up. I would just like to use Pocket Rx/Tx as a simple remote to say change frequency if i'm listening in another room.

Anyone got any ideas?

The jarecmini (no-GUI) version 0.9.0-1 (wit the same features as the GUI version with the same number) is available for download here:
https://www.yo3ggx.ro/jAReC/jarecmini_v0.9.0-1.zip
This includes a sample cfg file, but you need to edit it for your own use.

Some command line switches are now available:
"-h" - display current settings and exit, even if autostart is enabled
"-a" - force autostart even if disabled in the config file

Please post here your finding if you test it.

Thank you

Hi Dan,

Thanks for updating this so quickly but unfortunately I still get a similar error using Pocket Rx/Tx v0.9.0 and jarecmini v0.9.0-1:

not being very experienced with java and the raspberry pi this doesn't really mean a lot to me - hope it does to you!

Hi,

I've double checked and there is not a single trace of javafx in jarecmini code, so it may be something specific to your Java.
Some links that may help:

What Java version are you using on your Raspberry Pi?

I have tried a few version and get the same. I have just tried a clean install of Raspbian with the default java version shown below and still get the error.

Code: Select all

pi@raspberrypi:~/Downloads $ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)

[yo3ggx]

Can you downgrade the Java version to 1.8.0_31 or use OpenJFX?
