Rob,

Did you post this to Curt and the team? I saw something about an upgrade on the threads a couple of weeks ago, but it may not be related. 

There was an open bug against Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1702838

There is an issue going back to 2012 on this on the Xastir site:


You may need to google around a bit to find the exact fix.

Re: How to access the Hotspot on W3DJS Raspberry Pi Ham Radio Image

Daniel VA2DG
 
Edited

Never mind  i did use the old trick for Pi-Star.
Went to Pi-Star.uk and used the Pi-Star Wifi Builder then i was able to ssh to my Pi.
i had a look at the hostapd.conf and why the developper of this package does not state it clearly in his documentation that the password for the Wifi Hotspot is
wpa_passphrase=1234567890
There is nothing secret in this, it is like the default Raspberry login password.
If one of the user of this package would have put the password that would be more simple.
Anyway for other user that are having the same problem they can  use this link and generate the wpa_supplicant.conf with their own Wifi credential. Then they copy it
to the root directory of the SD card just after imaging it.  Then on the first boot the RPi will get registered to the user WiFi network.
Thanks for the heads up

KM4ACK, how can you SSH to PI if you have no connection to it?
Wifi is on Hotspot mode and need to connect to Rpi before i can SSH.


Re: How to access the Hotspot on W3DJS Raspberry Pi Ham Radio Image

km4ack
 

Open the terminal and run
cat /etc/hostapd/hostapd.conf
Look for wpa_passphrase= The password will be listed after the = sign.

Re: Raspberry Pi Zero + Baofeng UV-5R audio problems

Wayne Workman <wayne.workman2012@...>
 

Don,

This is an amateur radio application. Basically I'm working to mimic the functionality of these:

I have four of those. You might notice they are 160 dollars each. I'd like to have a great deal more along with better battery life and better transmit range, but the price is a problem.

If I can simply get the Pi Zero to properly activate VOX, I have all the other parts solved - like power, case, camera, software, and cost control thereof. Plus I'd have extra features like taking photos and video and storing those to SD card.

I've avoided things like the Signalink because of it's price.

Maybe all the cheap connectors is a waste of time. Maybe I should figure on a custom circuit to handle PTT and transmit audio.

Thanks,
Wayne

Is your time trying to figure this out worth the extra $25 for your project?  If it works on a Pi3, use that.  The Pi zero is a pretty basic machine and the circuitry is obviously inferior.

Hello,
 
As the title says, having some audio problems. My goal right now is to play a short .WAV file on my raspberry pi over the radio. Once I have this working, I'll use the capability in another project. I am using a USB audio adapter that works on my Raspberry Pi 3B+. I have an assortment of items I'm using, listed below.
 
btech APRS cable for UV-5R
 
3.5mm splitter to 3.5mm mic/headphone
 
USB Audio adapter
 
Baofeng UV-5R
 
Raspberry Pi Zero v1.3
 
 
It's all connected like this.


The Baofeng has VOX enabled, it's set to 1, which is the lowest sensitivity. I've tested that it does work with audio from computers using both my Ubuntu laptop and my Rasbperry Pi 3B+. The VOX works.
 
My raspberry pi is fully updated with latest packages, and also has these additional packages installed. The sox command being the one that provides the 'play' command I want to use.
sox motion openssh-server vim git
 
The following command shows me the USB sound card is device 1.
aplay -l
 
I've changed the default sound device on the raspberry pi by editing:
/usr/share/alsa/alsa.conf
 
Towards the middle of the alasa.conf file there are these two lines: I changed the card number to the correct one, in my case it's 1
## CHANGE:
defaults.ctl.card 1
defaults.pcm.card 1
 
I'm using this command to play the .wav file:
/usr/bin/play -v 1.75 /zones/zone_five.wav

Now, the problem. When I run the play command on the Raspberry Pi Zero with everything connected as pictured above, it's like the play command crashes for some reason. Pictured:


Here's the interesting part. When I connect this setup to my Raspberry pi 3B+, it works fine. The pi plays the file and the Baofeng's VOX activates and transmits the audio being played. Also when I connect headphones to the headphone port on the USB adapter while using the Pi Zero, it works fine, I can hear the file playing and it has decent volume, though a bit crackly no matter what volume I pick.

to boil it down, for some reason this setup is not working with the Pi Zero. I've been trying things to figure this out for a week, I'm at a dead end.
I am pretty good with Linux, but I haven't even the slightest of circuitry knowledge. I am mostly googling my way through that stuff.

Any ideas would be appreciated.
Thank you,
Wayne

Mark,

It's worth my time. If I can get it to work, I'm probably going to build 20+ of these. The whole idea behind this was to find a cheaper way.

Thanks,
Wayne

Is your time trying to figure this out worth the extra $25 for your project?  If it works on a Pi3, use that.  The Pi zero is a pretty basic machine and the circuitry is obviously inferior.

Just my 2 cents

Hello,
 
As the title says, having some audio problems. My goal right now is to play a short .WAV file on my raspberry pi over the radio. Once I have this working, I'll use the capability in another project. I am using a USB audio adapter that works on my Raspberry Pi 3B+. I have an assortment of items I'm using, listed below.
 
btech APRS cable for UV-5R
 
3.5mm splitter to 3.5mm mic/headphone
 
USB Audio adapter
 
Baofeng UV-5R
 
Raspberry Pi Zero v1.3
 
 
It's all connected like this.


The Baofeng has VOX enabled, it's set to 1, which is the lowest sensitivity. I've tested that it does work with audio from computers using both my Ubuntu laptop and my Rasbperry Pi 3B+. The VOX works.
 
My raspberry pi is fully updated with latest packages, and also has these additional packages installed. The sox command being the one that provides the 'play' command I want to use.
sox motion openssh-server vim git
 
The following command shows me the USB sound card is device 1.
aplay -l
 
I've changed the default sound device on the raspberry pi by editing:
/usr/share/alsa/alsa.conf
 
Towards the middle of the alasa.conf file there are these two lines: I changed the card number to the correct one, in my case it's 1
## CHANGE:
defaults.ctl.card 1
defaults.pcm.card 1

Hi just downloaded the image and burn it on a 32gb Micro SD, so far so good
Hook up RPi4 to HDMI, i have Keyboard/mouse.
Now i see RpiHotspot in  my wifi list
but what is the Password to connect to it.
I had a look in the Groups.io for over 4 hours and did not find any mention about how to login Wifi hotspot,   The only login/pass i saw is pi/raspberry.
