Re: Building on Orange Pi One SBC
Hi Dan,
I discovered that the GPIO pins are not the same as the Pi and
have to be defined in a FEX file. I do have the GPIO working now
by creating 4 GPIO ports then using GPIO3 for PTT on pin22 and
GPIO4 for DCD on pin 15. So far I have it driving LED via a 2k2
resistor.
Here are my working notes -
73, Nick.

Hello!
I
am interested too in GPIO settings for Orange PI
(One, Lite)
for
working with PTT, SQUELCH, but my Linux
programing skill are at low level...
Please
share your progress about this issue.
Thanks
in advance!

Re: Periodic audio device statistics [2 Attachments]
Hello Randy,
?
I was finally able to see what you said by
clicking "view source".
Yeah.. sorry about thast.? I think there is something wrong with the
new K9 Email reader for Android.? Nice work about thinking to
looking at the HTML source to see the plain text email!
6. Pulse audio should have been removed when I followed
the above document. I wouldn't know how to confirm that.
What Linux distribution have you installed on your Raspberry Pi?? I
would assume Rasbian Jessie version?? If so, it won't come with
PulseAudio so you're ok there.
7. I'm using a radio shack scanner that performed
perfectly as a receive only igate on my laptop PC for
months.
If you connect it to another computer, can that computer record the
audio like you'd expect?
8. As warned about in the document, I am not using a USB
hub.
Ok.
9. When I put audio into the microphone jack on the sound
card (using either a microphone or my scanner), it comes
out the speaker jack of the sound card and it sounds very
good. I can vary the volume levels using the mixer in
Linux so the card is communicating with Linux on some
level.
That doesn't sound right.? It shouldn't instantly and automatically
play the sound it hears or you risk feedback.? Check your mixer
settings using "alsamixer" from the "alsa-utils" package.? You can
install that with:
?? apt-get update
?? apt-get install alsa-utils
11. I have attached my configuration file and the text
copied from the Direwolf terminal when I start the
program.
In your config file, you have:
ADEVICE - plughw:1,0
When you should have "ADEVICE? plughw:1,0"?? (notice the missing -"
--
Instead of having:
MODEM 1200
I recommend the following for the Raspberry Pi:
?? MODEM 1200 E+ /3
--
If you can manage to get an LED and a resistor, I highly recommend
to setup a DCD indicator (lights up when Direwolf hears a packet):
#pin18 (GPIO 24) - (cathode) LED (anode) - 270ohm resistor - 3.3v
DCD GPIO 13
--
Unless you plan on using the TCP-KISS port or the AGWPE port, I
would disable them with
AGWPORT 0
KISSPORT 0
--
One thing that is suspicious to me is that the Direwolf
terminal shows "stdin" rather than my sound card as
"device for receive".
This is due to the "-" in the ADEVICE line above.? Remove that as
recommended above and I think you'll start hearing packets.

Re: Periodic audio device statistics
David,
I was finally able to see what you said by clicking "view source".
I have spent a lot of time on this and have read the documentation...over and over and over again. I have read many other threads. I've tried many things. I've exhaustively done my homework. I know how forums work. I wouldn't bother you but I don't know where else to look for an answer anymore. I'm here because I am desperate.
I have answered most of your questions previously in this thread. It seems like I'm just chasing my tail here. Not that I don't appreciate the help, the forum (Yahoo) just doesn't seem to be very efficient. I really don't feel like typing everything over again just to add more clutter to this thread...but here goes...
1. I am setting up a receive-only igate. No transmit.
2. I am using a Syba USB sound card. It indicates CMedia CM119 on the package. This sound card is recommended in the document I list here in #5.
3. I have tried putting an isolation transformer and also a capacitor to block the 5 volts at the sound card input, but it did not help.
4.? I am running version 1.3
5. I've been following what has been done before in the document at this link...
6. Pulse audio should have been removed when I followed the above document. I wouldn't know how to confirm that.
7. I'm using a radio shack scanner that performed perfectly as a receive only igate on my laptop PC for months.
8. As warned about in the document, I am not using a USB hub.
9. When I put audio into the microphone jack on the sound card (using either a microphone or my scanner), it comes out the speaker jack of the sound card and it sounds very good. I can vary the volume levels using the mixer in Linux so the card is communicating with Linux on some level.
10. When I type "arecord -l", it lists my C-Media card as "card 1".
11. I have attached my configuration file and the text copied from the Direwolf terminal when I start the program.
One thing that is suspicious to me is that the Direwolf terminal shows "stdin" rather than my sound card as "device for receive".
Again, thanks for your help.

Re: Building on Orange Pi One SBC
hello Nick i orderd a OP1 in October and it came from China just at the end of November it was DOA they wanted me to send it back then they would send me another of course the return shipping was more than the item i just ordered another it came a month or so later and it was also DOA? different failure, but still non functional so im not holding any hope of ever having a OP1 that runs
Glad your is running !

Building on Orange Pi One SBC
I just got myself a cheap Orange Pi SBC to experiment with and to see how it compares with my Rpi and Pi3. These devices are available for around 12USD from the far east although I paid slightly more from a UK source. That's about half the price of a Pi3. HDMI video and a keyboard is required for initial setup although I managed to do most of it over ssh once connected to my network over ethernet.
After installing the Ubuntu flavour of Armbian LInux, I found the compiler tools and git already installed. I pulled a copy of the Direwolf git repository as per the manual but my first build attempt failed due to missing library and header files.
These were downloaded by a "sudo apt-get libasound2 libasound2-dev libgps22 libgps-dev". Building completed followed by sudo make install and make install-conf.
I connected a usb sound card and configured with alsamixer. This was listed as card 2 so I adjusted direwolf.conf accordingly.
It's currently sat there on the bench connected to a HT monitoring my main APRS node and anything else in close proximity on 144.8. It's also connected to APRS-IS as G4IRX-1. Next challenge is to figure out the GPIO for a PTT and RX led interface. GPIO needs further configuration.
More details on the Orange Pi here - and Armbian Linux here -

Re: Digipeating fails but Igate continues to function - Windows 7
We have been noticing this on a Raspberry Pi, using a DIO for PTT control.? It happens randomly, but at a much longer timeframe - a couple weeks to a month or so.? The system is remote, so we can't physically?observe it, but we can ssh into it.? We are now logging DW's output, and also monitoring it at another station.
Just now I was able to connect to it with APRSIS32 via a KISS port, and it was receiving well and may have transmitted a packet or two from that.
In every case, simply restarting DW has gotten it going again.? The RPi itself has been up for a long time, and we don't have to reset it.

Re: Periodic audio device statistics
Hello
?
Okay...tried the recording and nothing on it. I had tried
this before with the same results. I sent the wav file to
my PC and it was silent. Other wav files play fine on my
PC.
Is it for sure that if there is nothing on the wav file,
I would argue that it's 99% for sure that if you can't record the
audio coming in from the USB soundcard's microphone jack, something
is wrong.? I would not worry about Direwolf until you can get it to
record the open squelch noise from your RX radio or some other audio
source.? Please also note that it's important that you add a
decoupling capacitor from the USB soundcard's microphone port to
your radio's audio output.? There is a multi-volt BIAS voltage
coming from the USB device that can harm your radio if it doesn't
have any decoupling circuitry itself.
This is why I wanted to get the periodic device
statistics. Do you have any idea why they do not work?
Could I be typing the command incorrectly? At the wrong
place? Exactly how do you enable the statistics? "direwolf
-a 10"?
Please tell us about your setup:
?? - Radio you're using
? ? ? - Are you using PTT or VOX
?? - Specific USB sound card you're using
???? - How is it connected?? Direct to the Raspberry Pi
(recommended), connected behind a USB hub (not recommended)
?? - Paste in the configuration of your direwolf.conf file
Could it not be working because I don't have the Direwolf
configuration file correct?
Yes, that would cause it.? Please read the documentation and
complete all of the recommended settings before emailing the list
asking why it doesn't work.

Is it for sure that if there is nothing on the wav file, Direwolf is not hearing input on the sound card. Also, is the inverse true? If there is audio on the wav file, can you be certain Direwolf is getting the audio?

Re: Periodic audio device statistics
I really didn't want to write up all the things I have tried in the last two weeks. Nor did I want to force you to read all of it.
I've been trying to follow what was done in the document at the link below...
I purchased one of the sound cards recommended in the pdf.
As I said, I'm no Linux expert. I did execute the commands in the document to remove Pulse, but I wouldn't know how to confirm it was successfully removed.
I have a degree in electronics and over 30 years of experience in the business so you can get technical about electronics. For things specific to Linux I will need detailed help.

My first attempt with?telemetry.? This large Direwolf project got me to this point in one day.? Thanks.? Running on a Raspberry Pi 3, Raspbian Jessie.
Using SENDTO=RO to troubleshoot. Getting "Found fewer than expected number of telemetry data values." error message.
Here's the config: CBEACON delay=0:10 every=10:00 sendto=RO via=WIDE2-1 infocmd="telem-parm.pl K7UOP-1 Temp Batt"
CBEACON delay=0:12 every=10:00 sendto=RO via=WIDE2-1 infocmd="telem-unit.pl K7UOP-1 degF Vdc"
CBEACON delay=0:14 every=01:00 sendto=RO via=WIDE2-1 infocmd="telem-data.pl `telem-seq.sh` `~/bin/aprs/get-values.py`"
And here's the direwolf output:
[0.0] K7UOP-1>APDW13,WIDE2-1::K7UOP-1? :PARM.Temp,Batt
Telemetry Parameter Name Message for "K7UOP-1", Ambulance, DireWolf, WB2OSZ
[0.0] K7UOP-1>APDW13,WIDE2-1::K7UOP-1? :UNIT.degF,Vdc
Telemetry Unit/Label Message for "K7UOP-1", Ambulance, DireWolf, WB2OSZ
[0.0] K7UOP-1>APDW13,WIDE2-1:T#685,57.4,12.5
Found fewer than expected number of telemetry data values.
Telemetry, Ambulance, DireWolf, WB2OSZ
Seq=685, Temp=57.4 degF, Batt=12.5 Vdc
Note that I'm using raw decimal numbers (57.4,12.5)?for values instead of three digit integers. Also BTW,? the APRS-TW program does not display these decimal values. It shows zeros? (with raw values being the integer of my values). It also indicates 5 analog and 8 digital readings.
I also wonder about the decoded?"Ambulance" thing too.
I plan to decode my own data so I don't think these are an issue for my purpose. But it would be nice if other programs could see that proper data.

Re: Periodic audio device statistics
A good step #1 would be to try to record the audio from your Rpi and see if you can play the audio back though a connected pair of headphones, etc. Though more command line centric, you can follow these steps to troubleshoot your setup:

It would be helpful to know if audio is routed into the application and what level it is.
I suspect the fact that these reports do not show up may be related to the audio not making it to the program.

Re: Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.
I want direwolf to hand it off to the? APRS-IS network, which is what I'm struggling with as it keeps trying to send it over RF which does not exist.
APRSIS-32 works fine using?APRS-IS, ?but I don't want to use it like that.?

Re: Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.
You need to make a decision -- do you want direwolf to communicate with the APRS-IS network, or do you want it to hand off to APRSIS-32 and let APRSIS-32 handle the connections to the APRS-IS network? I would suggest the second option, in which case this becomes an APRSIS-32 issue, not a Direwolf issue. There is a good support forum for APRSIS-32.

Hi Matt,
AGW/KISS is set up correctly in APRSIS-32
I am actually receiving messages, if I disable Tx then it won't try and tell direwolf to send the message or ack, how do I get direwolf to treat anything sent over the KISS/AGW port to send to an via the APRS-IS server.

Re: Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.
Configuration will be in APRSIS-32 -- you need to set up the AGW port that faces your direwolf modem to handle messages and to enable TX (although if you don't have a transmitter connected, better to leave TX disabled in the APRSIS-32 settings).

I have direwolf set up as an IGate and using the Pseudo Kiss or AGW setup on my APRSIS-32, Data is being sent to APRSIS-32 and can see all the stations my Rx only IGate is picking up.
I have 2 issues:
1, Any message being sent to me does not appear on APRSIS-32 nor does it send any ack packet. 2, Any message via?APRSIS-32?I send shows on my direwolf console shows direwolf trying to send it as a radio packet, however I have no Tx capable radio attached and is Rx only.
Is there a config I need to add or change for KISS/AGW to enable me to use a client attached as described.

Re: Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.
Sorry I am actually receiving messages,
However direwolf is trying to send messages and ack as over Rf not the igate.
