jarecmini on a raspberry

[balans]

Hi i am still in a beta stadium but i wanted to share my findings so far

I installed raspbian 2015
plugged in my USB PnP Audio Device since the raspberry does not have line or mic in.
check with the command alsamixer
toggle with F6 to see your usb card example USB PnP Audio Device or somewhat simulair
tune youre input and output levels up and exit
type alsactl store to save the settings

download jarecmini.zip
unpack and edit jsn.cfg

sCOMport=COM6

to
sCOMport=

and save

execute java -jar jarecmini.jar

and if al is ok you should see something like this

jAReC mini version 0.8.1
Please set valid Serial port in the jsn.cfg configuration file

IInvalid audio device
Current settings:
COM Port:
Baudrate: 38400
TCP port: 4443
Use audio: true

Use authentication: true

Available com ports:

Available Audio OUT devices:
(00) ALSA [default]
(01) ALSA [plughw:0,0]
(02) ALSA [plughw:0,1]


If ok, set bAutostart=true in the jsn.cfg file and run again

edit jsn.cfg

sCOMport=/dev/ttyUSB0 ( i use an external usb cable)

now notice the numbers with the Audio in and Out and edit these lines
iRecInterface=3
iPlayInterface=0

the 0 come off , and then save and execute again

root@raspberrypi:/home/pi/Downloads# java -jar jarecmini.jar
jAReC mini version 0.8.1

Listening for connections on 192.168.1.28:4443
Remote IP: 192.168.1.232
Start Audio


and then use Pocketrxtx to connect
I had to use the default audio out connector on the raspberry but the mic/line in works from the usb
I tried to make the audio out from the usb but failed miserably , but this way it worked so far and thats ok with me.
I do still have a problem with the CAT and my FT817 it starts with TX when jarecmini starts.
when i use pocketrxtx the audio from the mic works , when i start jarecmini with the CAT cable disconnected from the FT817
I have audio from the set on my android smartphone true Pocketrxtx.

So this projects looks very promising for a lowcost lowpower remote solution.

I hope to figure out whats wrong with the cat on my side or with Dan on the jarecminiside

I am new to Linux can you tell me how to unpack and edit jsn.cfg ? I get an error telling me to create jsn.cfg.

Hi,

You can follow the procedure described in the jarecmini user guide available here:
https://www.yo3ggx.ro/jAReC/doc09016/jA ... 9.0-16.pdf

Hope this help.

I read that but doesn't tell me where I find the jsn.cfg file. I unzipped the file I downloaded and there was one file there. When I try to open it I am told to create the jsn.cfg file.

I went back and downloaded jarec v8 and the jsn.cfg file was in that zip file. I have it going now just trying to get the network connection figured out.


Thanks

Yes, this is the easiest way to build a config file and currently the only way to set the password hash.
What's the issue with the network?

Sorry I put this in another thread

OK I got the jsn.cfg file from version 8 of jAReC. I set it up and run jarecmini.jar

pi@kd4kso:~/Downloads/jARec $ java -jar jarecmini.jar
jAReC mini version 0.8.1

main._appstart (java line: 279)

The I start Pocket RxTx on my Andriod tablet and when I try to connect the console on the Pi does this:

I tried running jAReC v 9 with the same jsn.cfg and it won't recognize the comm port. I have the file set to /dev/USB0

pi@kd4kso:~/Downloads/jARec $ java -jar jAReCmini_v0.9.0-16.jar
Please set valid Serial port in the jsn.cfg configuration file

If ok, set bAutostart=true in the jsn.cfg file and run again


This is what the cfg file actually says:

Hi,

Sorry I put this in another thread

OK I got the jsn.cfg file from version 8 of jAReC. I set it up and run jarecmini.jar

Please confirm that you are trying to use jarecmini 0.8.x with Pocket RxTx 0.8.x
Take care that version 0.8 config is not good with 0.9.0-16, as some parameters are missing:
sPTTport=...
PTT=...
Please check jAReC 0.9.0-16 user guide here:
https://www.yo3ggx.ro/jAReC/doc09016/jA ... 9.0-16.pdf
at page 7 (configuration file)

Pocket RxTx 0.9.0-18 require jAReC 0.9.0-16, is not compatible with previous versions.

java.lang.RuntimeException: java.lang.NoClassDefFoundError: javafx/beans/value/ChangeListener

It looks like it tries to use javafx which is not available on your Raspberry Pi.

I tried running jAReC v 9 with the same jsn.cfg and it won't recognize the comm port. I have the file set to /dev/USB0

Please check the new parameters for 0.9.0-16.

OK I have that part now. I copied the information to the cfg file. You told me to use jAReCmini. When I try to run the jarecmini file it doesn't see that I have a comm port listed. When I remove the jsn.cfg file and run it for the first time like the mini manual says it does not create the the file but instead tells me to create one. This is what my config file says

#Wed Sep 21 17:12:29 EET 2016

bUseEncryption=false
iPTTtimeout=30
sBaudrate=38400
