Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

john.chabalko@...
 

I've got this working, it does exactly what i was looking for. It will join my home Wifi when i'm at home, and if my home wifi is unavailable (eg: i'm out somewhere) it'll configure a static IP address on the RPi wlan0 interface, fire up a hotspot and i can connect to that from my computer/tablet/phone and use the Rpi as a standalone device.

Here's the link i ended up following.

It's a little bit fiddly in that it seems to take a while to bring up the access point after reboot. I was debugging the autohotspot script and all i can see is that it fails while provisioning the interface due to device busy, but then after ~2 minutes it works (i run the pi headless so am looking at the logs after the fact.

SSid's in range:  ++ iw dev wlan0 scan ap-force ++ egrep '^BSS|SSID:' command failed: Device or resource busy (-16)

The next thing i'm going to mess around with is if i can get it to join the "personal hotspot" from my phone/tablet and let me connect to it and have internet access from the RPi while i'm not at home.

Glad to find the tech doc.  Is the spec for the RTC backup battery there?  I didn't see it.  Glad to see the 6 pin mini-DINs compatible w ICOM and Yaesu.  

Thank you,

Re: DRAWS Technical Documents

 

The RTC is an integrated part of the GPS and not addressed separately.

The battery is to preserve values when power is removed. The battery can provide a cumalative 40 days of backup power before replacement.

Re: Using a PiDrive with Draws HatUsing a PiDrive with Draws Hat

nwdigital radio customer service rocks. Here's an update. I got the confidence boost I needed from NWdigital Radio and plugged the 12 volts in. My Draws Hat is working and there seems to be no problems. It is up on aprs again. I plan and running it for the next week on aprs  them try some HF. If all goes well I will then try my PiDrive, as I see others had the same idea. I hope I did not scare anyone away for experimenting. It is the hobbies way to experiment. Anyway I'm really diggin' this toy and look forward to doing alot with it. I currenly running a Ultimeter 2100 on the pi with draws hat connected to my 847. It is up on cwop and aprs.fi

Howdy all,
Here's an update. I received my pi3B+ and hooked up my draw hat. I did not use the 12 volt power I used the Pi power instead. I have a working Xastir station now. So not sure if I really did any damage when trying on my pidrive. I just don't know what the smoke was from and I am gun shy now of trying the 12 volt input again. I really want to but I really wanted to play first. I'm using a Yeasu ft-847 as I want to try the ft8 digital format. I left the new pi and draws hat powered up overnight with the radio turned off just in case. All seems well today. More to come.

I'm not an expert but I believe it will work on the PiDrive as long as you use the PiDrive power instead of the 12 volt supply. My new Pi3B+ should be in by this weekend. I will try my draws on it and see if I still has troubles. As far as my PiDrve it is working just fine. So the draws hat is what may have been what was damaged. If you can wait awhile I will update with further details.

I wanted to use my PiDrive as it is already setup as my access point and dhcp server to my ham shack on wheels. I plugged the hat in and hooked up an external 12 volt source. When I powered it up it gave me a smoke signal. I quickly disconnected power. So I then hooked it up to a pi2 that I have. Using the same 12 volt cable it fired up both the pi and draws hat. But it is not recognizing a sound card. I have ordered a pi3 B+ and will try it on that when it arrives. I hope I did not blow the card. showudrc.sh shows it sees the draws hat.

Re: fldigi with DRAWS #draws #fldigi

KeithG [KG1MD]
 

I burned the image to a chip, booted the pi/draws hat and had no trouble following the update instructions to update the software/system.
I am using a monitor, keyboard and mouse directly connected to the pi.
I have been able to get my ICOM IC-7300 and pi to talk together and pass audio both ways using the IC-7300 USB connector plugged into the pi.  I have tried and configured all of the non packet modes with success!
[Not being particularly savy with the pi or my new IC-7300, I am quite prowd that I have been able to get this far :)]

The one BIG issue that I am having is using fldigi - the main reason that I got the draws hat:

I have it working and communicating via the USB like the other software.  The issue is that fldigi will load and run perfectly for only a few minutes, then without changing anything on the radio or pi, the waterfall will start to pause/stutter, getting worse as the minutes go by until the program will ultimately freeze requiring a reboot.  Not even taskmanager is able to kill it every time.

The drop down menus will sometimes work for a bit before the program ultimately crashes.

When I frist got fldigi working, I made several contacts on PSK31 and CW, but then it started acting up and getting flaky.  I had been using a 2.5A 5V wall wart to power the pi/draws and thought that it may have been the power, so I connected the 12V hat leads to my 12V supply with no change in the behavior of fldigi.  The other software all seem to continue to work fine.

Any suggestions will be GREATLY appreciated!  [I'm DYING to try some of the other digital modes and see if I can get WEFAX images and SSTV!!]

Thank you in advance!

Congrats on getting through the setup portion!

Sounds like you're only connecting through USB?

If you're not connecting through the ports on the draws to the radio, then it wouldn't be a draws problem.

Can you connect your draws hat to your radio through one of the 6-pin ports and use the draws audio ports without it freezing?

locked DRAWS + FT-891 + WSJT-X/FT8

Steve McGrane <temporarilyoffline@...>
 

Trying to get WSJT-X working for the next video. Details First, Questions at the end.

Radio: Yaesu FT-891
CAT control works over USB
Radio connected via LEFT Audio port (closest to GPS port)
RIGHT Audio port disabled via DRAWS Manager
I’ve ran `sudo bin/setalsa-ft817.sh`

Audio Input of `sysdefault:CARD=udrc/Mono` works fine and I’m decoding signals

I am unable to find an audio output setting that does anything.  Valid choices are:

default
sysdefault:card=alsa
sysdefault:card=udrc
hw:card=alsa,dev=0
plughw:card=alsa,dev=0
plughw:card=alsa,dev=1
plughw:card=udrc,dev=0

This radio works fine with a separate signalink and linux PC.

The FT-891 manuals do not specify what the “Peak to Peak Input Voltage” is, so I can not complete the calculations.

It appears that when the software triggers the PTT, that ambient shack noise is being transmitted instead of the audio/data stream from the DRAWS. (I can't whistle FT8 yet, but I'm getting close)

I have not pulled out pin 6 yet, the prev thread with Julian didn’t conclude if that was necessary or not.

Questions:
  1. What is the Peak to Peak Input Voltage of the FT-891
  2. What is the proper sound output device
  3. Any suggestions for what might be missing or what to try next?
73s,

Re: fldigi with DRAWS #draws #fldigi

john.chabalko@...
 

Something you could try to narrow it down - although i doubt it'll show much - is to disconnect the radio from the pi, run fldigi for a period of time and see if it goes unresponsive, and then depending on what happens, remove the DRAWs hat from the pi and try running fldigi with and without the radio connected.

What version of fldigi are you using and which raspberry pi are you using? I've got 4.1.01 on mine - which appears to be the latest, i'm pretty sure i've updated it since i burned the disk image though.

DRAWs hat audio not working after Rpi update

john.chabalko@...
 

I ran a late night dist-upgrade last night on my card running the draws image (i know, i know)

Everything appears to work correctly except each of the programs that use audio are complaining of no input audio. When i navigate into the settings input and output audio are both blank. I can select output audio (plugw:CARD=ALSA,DEV=0) but the dropdown for input audio isn't populated with anything. CAT control, and everything else, seems to work fine.

I'm running at FT-891 connected via USB and DRAWs audio. The Rpi is a 3b+

I'm going to do some more troubleshooting later tonight, i figured i'd post this here in case it's a softball for anyone.

Re: fldigi with DRAWS #draws #fldigi

I’m using a RPI 3 B+
After running the updater, it tells me that fldigi will be updated to 4.1.01, but that never happens.  I’ve run the updater several times.  Is there a step I’m missing?

I will disconnect the rig and see if fldigi continues to run.

Tnx again!

Re: fldigi with DRAWS #draws #fldigi

I’m new to the raspberry pi too but I think you’ve got to initiate the update yourself, or at least you could check

Assuming your rip is connected to the internet, 
Shut down fldigi, and then in a terminal window type:
sudo apt-get upgrade fldigi 

answer yes (or hit enter) and you’ll get the update.

once it’s done you can reopen it. 

Re: fldigi with DRAWS #draws #fldigi

Stick with the beta images and pre-installed applications using the startup instructions from Basil. Once you have a working install, then you can experiment with updates and changes.

I have the same rig and have had it working great (until tonight when i ran a dist-upgrade ;) )

There's an FT-891 menu setup that you need to configure that i think will fix your transmit audio problem.
Menu 08-09: Data In Select: REAR

That should use the rear data port for audio, yours is probably set to "mic" which is the default i think.

Since mine isn't working at the moment because i'm rebuilding it i'm using my notes - but the audio devices i was using were:
Input: plughw:CARD=udrc,DEV=0 (mono)
Output: plughw:CARD=udrc,DEV=0 (mono)

I'm using the same port you are (next to the GPS port).

I don't know the peak to peak voltage but i'd been running mine with the program defaults and it was working fine, i hadn't been able to spend much time yet fine tuning it.
