Pi-Star is great software for digital voice hotspots and repeaters. It can handle DMR, D-STAR, and YSF, and even P25, NXDN, and YSF and DMR cross modes when used with a multi-mode digital voice modem that supports those modes.

Andy Taylor, MWØMWZ, the main developer, says this on his Pi-Star website⩘ :
"Pi-Star can be whatever you want it to be, from a simple single mode hotspot running simplex providing you with access to the increasing number of Digital Voice networks, up to a public duplex multimode repeater!"

Disclaimer:  These are my personal notes based on setting up and using Pi-Star hotspots as a non-technical user figuring things out as I go along, as well as by learning from what others are sharing. I'm not affiliated with the Pi-Star project, except as an enthusiastic user. If anything needs correcting, please let me know.

1) Learning about Pi-Star

Pi-Star is relatively easy to set up as a personal hotspot, so don't be put off by the length of this article. It's long because it covers a lot of the rich set of features and configuration options, beyond what's needed to set it up for the first time.

1a) To get up and running

Go through the setup steps in sections 1 - 5, marked with a circled red S.
Also go through the setup steps, marked with a red star, for the digital modes you want to use: choose from DMR, D-STAR, YSF, P25, and NXDN.

1b) Some good resources for learning about Pi-Star

1c) Having trouble?

For some hints about how to proceed, see: Pi-Star troubleshooting⩘ .

1d) Using D-STAR? Be sure to set up your radio properly!

For most hotspot devices, DV mode won't work; instead, you must use D-STAR Repeater (DR) or Duplex mode: set up RPT1, RPT2, and a zero offset (either +/−0.000). For more info, see: Use DR mode!⩘  See also the video: D-STAR Radio Primer for using Pi-Star⩘  by Craig, W1MSG.

2) Downloading Pi-Star

If your hotspot came with a microSD card loaded with the Pi-Star image, skip ahead to step 3a. Otherwise, your download the Pi-Star image from Pi-Star Downloads⩘  to a Windows, Mac, or Linux-based computer (not the hotspot). If your hotspot uses a Raspberry Pi, download the RPi image.

Pi-Star downloads page

Note: At this time, the regular Pi-Star RPi image doesn't support the new RPi 3B+; however, there is a beta version that does: Pi-Star Beta Downloads⩘ .

3) Flashing Pi-Star

Extract the downloaded Pi-Star image zip file, and then flash the image file itself (ends in .img) to a 4GB or higher microSD card. A great app for this is Etcher⩘ , available for Windows, Mac, and Linux.

You can ignore any system message you get that says you need to format the microSD card when you first insert it or after you finish flashing the image. During the Flash step, Etcher formats the card, writes the image, and verifies it was written correctly.

3a) Preparing to connect to WiFi

Using the built-in Auto AP (Auto Access Point) method

If you're using Pi-Star 3.4.11 or later with a Raspberry Pi 3 or Zero W and Auto AP is enabled (which is the default), you don't need to do anything else to prepare to connect to WiFi. For more info, see following: 4) Booting up Pi-Star.

Note: Auto AP also works with some WiFi dongles, depending on their chipset. Andy Taylor has posted a list of dongles that work⩘  in the Pi-Star User Forum.

Manually preparing to connect to WiFi

If you can't use Auto AP or you just like to do things manually, after you finish flashing the image to a microSD card, you can manually add your initial WiFi settings to the boot partition so they'll auto-install on first boot up:

  1. Create a wpa_supplicant.conf file with your WiFi settings:
  2. Copy the wpa_supplicant.conf file to the microSD card's boot partition. Note: The next time you boot up Pi-Star, the file is automatically moved to /etc/wpa_supplicant/, so you won't find it in the boot partition anymore.

3b) Preparing yourself and your hotspot for first boot up

Grab a cup of coffee or tea and insert the microSD card into your hotspot.

4) Booting up Pi-Star

Okay, take a deep breath. Step 4 can be the most challenging one. What you need to do depends on your circumstances. Do all the following that apply:

PDF: 2-Pi-Star_Auto_AP.pdf · Related video: Pi-Star WiFi Auto AP⩘  by Craig, W1MSG

4a) For all boot-ups

  1. Power on your hotspot.
  2. Wait for Pi-Star to boot up, which normally takes a minute or so (a bit longer when using a slower computer like the RPi Zero W).
    Note: If your hotspot has a display, you can watch Pi-Star start up until the login prompt is displayed, but don't bother logging in there because you can't set up Pi-Star via the hotspot.

4b) If using Auto AP and setting up a new WiFi connection

Perform this step when you start Pi-Star for the first time or when you need to connect to a new WiFi network, for example, when traveling. When Pi-Star doesn't find a known network within two minutes after boot up completes, Auto AP will automatically activate its own access point, and you'll use that to connect to Pi-Star in order to configure WiFi settings.

  1. Wait two more minutes for Pi-Star Auto AP to activate its access point.
  2. On a Windows, Mac, or Linux-based computer (not the hotspot itself) that has WiFi enabled, look in the WiFi settings to find the Pi-Star access point, and then select it to connect to it:
    • If you're starting Pi-Star for the first time, it'll be named "Pi-Star-Setup." This is what it looks like on a Mac:
      WiFi selector on macOS - first time startup
      If this isn't the first time, but you need to connect to a new WiFi network, it'll be named using the hotspot's hostname, by default, "pi-star" (or whatever you changed it to in the General Configuration settings).
  3. Enter the Pi-Star-Setup network security password: raspberry.
    Authentication Required
    • Note: Depending on your computer, the network password may be called the WPA2 password, the Network Security Key, or something else. You may need to enter the password two times.

4c) For all boot ups

On a Windows, Mac, or Linux-based computer (not the hotspot itself) that has WiFi enabled, open a browser window and navigate to:

Note: On some mobile devices, the url won't work. In that case, you can try the Auto AP mobile IP address: 192.168.50.1

4d) If starting Pi-Star for the first time

You'll be greeted by a "No Mode Defined" screen, which is normal because you haven't yet configured the mode to use.

No Mode Defined

  1. At this point, you can either click the Configuration link or wait 10 seconds to be redirected automatically to the Configuration page.
  2. Configuration requires authentication. The default user name is pi-star and the default password is raspberry (you can change the default password later on in the configuration process). This is what it looks like on a Mac:
    Authentication Required

4e) If using Auto AP and setting up a new WiFi connection

Perform this step when you start Pi-Star for the first time or when you need to connect to a new WiFi network, for example, when traveling.

  1. If you're not already in Configuration view, click the Configuration link and log in with your Pi-Star user name and password.
  2. In the Configuration view, scroll down to the Wireless Configuration section.
  3. To add or modify your WiFi network connections, click Configure WiFi.
  4. Click Scan for Networks (10 secs). It won't look like anything is happening.
    Note: If the scan doesn't find the network you want, you can add it manually, as discussed below: 5j) Wireless Configuration.
    WiFi configuration
  5. In the list of networks found, select the one you want.
    WiFi configuration 2
  6. PSK: Type the wireless network password. The PSK field will turn green.
    WiFi configuration 3
  7. Click Save (and connect). When Auto AP is active, this step will only save; it won't connect. Wait a few moments for it to save (PSK field will turn white again), and then reboot Pi-Star. (If you're unable to reboot, power the hotspot off and back on again.)
  8. While the hotspot is restarting, reconnect your computer to the regular WiFi network you're using.
  9. After the hotspot reboots, Pi-Star will connect to the new WiFi network you added. On a Windows, Mac, or Linux-based computer (not the hotspot itself) that has WiFi enabled, open the Pi-Star dashboard by navigating again to: http://pi-star/ or http://pi-star.local/

Congratulations! You've finished the most difficult part of setting up Pi-Star.

5) Performing initial Pi-Star configuration

After authentication, the Configuration view is displayed. I'm going to discuss these configuration settings in three parts: Basic, Digital mode, and Additional.

5.1) Basic configuration settings

This first set of configuration settings covers the Control Software, MMDVMHost Configuration (if MMDVMHost is enabled), and General Configuration.

5a) Control Software

DMR cross-mode configuration

Digital mode configuration settings - DMR cross-modes

Note: This screen capture is for illustration purposes only and is not a realistic view. Normally when you are using a DMR cross-mode, you would have only one of the cross-modes enabled.
Ron, VE1AIC, has a good overview of how this feature works: 2018-05-30⩘ .

DMR2YSF – To use the optional DMR2YSF capability (requires Pi-Star 3.4.14 or later), in the MMDVMHost Configuration settings, enable both the DMR and DMR2YSF modes (normally, you also should disable YSF, NXDN, and P25 modes, as well as other cross modes). After you have applied changes, you'll see both the DMR and Yaesu System Fusion Configuration modules.

Next, watch the DMR2YSF video⩘  by Craig, W1MSG. He clearly explains the two different ways you can set up and use this feature.

If any changes made, click Apply Changes.

DMR2NXDN – To use the optional DMR2NXDN capability (requires Pi-Star 3.4.15 or later), in the MMDVMHost Configuration settings, enable both the DMR and DMR2NXDN modes (normally, you also should disable YSF, NXDN, and P25 modes, as well as other cross modes). After you have applied changes, you'll see both the DMR and NXDN Configuration modules.

5.3) Additional configuration settings

5j) Firewall Configuration

Additional configuration settings - Firewall Configuraiton

Auto AP (Auto Access Point)

The Auto AP feature, which works with the Raspberry Pi 3 and Zero W, was added in version 3.4.11. If the feature is enabled (which is the default), after Pi-Star boots up (takes about a minute), it will attempt to connect to a known WiFi network. If it can't connect within another two minutes after boot up, Auto AP automatically activates its own network access point, which you can use to connect to Pi-Star in order to configure WiFi settings.

Auto AP makes it easier to connect to a new WiFi networks when you start Pi-Star for the first time or when you need to connect to a new WiFi network, for example, when traveling. For more info, see above: 4) Booting up Pi-Star.

Some additional notes about Auto AP:

uPNP (Universal Plug and Play)

Note: If your router doesn't support uPNP or you disabled your router's uPNP capability, then this setting has no effect.

Dashboard Access, ircDDBGateway Remote, SSH Access

Note: These settings have no effect if your router doesn't support uPNP or you disabled either your router's uPNP or Pi-Star's uPNP setting (see previous).

These settings are used for accessing the dashboard remotely, from outside your network. Per Andy Taylor in the Pi-Star Users Support Group: "These settings tell the uPNP daemon to request port forwards from your router."

If any changes made, click Apply Changes.

5k) Wireless Configuration

Additional configuration settings - Wireless Configuraiton

  1. To add or modify your WiFi network connections, click Configure WiFi.
  2. You then have two options:
    Scan for WiFi networks
    1. Click Scan for Networks (10 secs). It won't look like anything is happening. If the scan doesn't find the network you want, you can add it using the manual method described next.
      WiFi configuration
    2. In the list of networks found, select the one you want.
      WiFi configuration 2
    Manually add a WiFi network
    1. Click Add Network.
      WiFi configuration - add network
    2. SSID: Type the wireless network name. Note: A space in the network name can cause problems with connecting to some routers.
      Add WiFi network
  3. PSK: Type the wireless network password. The PSK field will turn green.
    WiFi configuration 3
  4. Click Save (and connect). It may not look like anything is happening, but give it time until it's finished and the PSK field turns white again.
    - - - - - - - - - - - - - - -
    Auto AP note: If you're setting up a wireless connection using Auto AP, this step will only save; it won't connect. Wait a few moments for the save to complete, and then power your hotspot off and back on again.
    1. While the hotspot is restarting, reconnect your computer to the regular WiFi network you're using.
    2. After the hotspot reboots, Pi-Star will connect to the new WiFi network.
    - - - - - - - - - - - - - - -
  5. Optionally, you can add additional wireless network connections. If you have multiple wireless network connections, when you boot up Pi-Star, it will scan each one in turn based on its priority until it finds one to connect to:
    • Be patient, each connection attempt takes about 40 seconds.
    • The first wireless network connection you add is given an ID of 0 and a priority of 100. For each additional wireless network connection you add, the ID is increased by one and the priority is decreased by one. Thanks to Bob, NØYWB, for his post in the Pi-Star Users Support Group explaining how this works.
    • For more info, see: Manually adding WiFi settings to RPi⩘ .

5l) Remote Access Password

Used for accessing Pi-Star Admin and Configuration settings, and SSH access.

Strongly recommended: In order to protect your settings and network, change the password from the default to something stronger and more challenging to hack. A challenging password is even more critical if you make your dashboard publicly accessible in the Firewall Configuration section.

Remote Access Password configuration

  1. The user name is pi-star, and can't be changed. This is different from the Hostname that can be changed in the General Configuration settings.
  2. In the Password field, type your new password, preferably something long and strong.
    Note: Some special characters work for accessing Pi-Star Admin and Configuration settings, but not for SSH. For example, a tilde symbol (~) works for logging into Pi-Star Admin, but not for signing in via SSH.
  3. Confirm your password. Once you have typed an identical password, the field turns from red to green.
  4. Once you get the green confirmation, click Set Password.
  5. Once the password has been set, the Authentication Required dialog box will be presented, and you can sign in using your new password.

6) Running Pi-Star

Once you've finished the initial configuration, running Pi-Star is easy. Just start your hotspot and give Pi-Star a minute or so to fully boot up. As long as you have your radio set up correctly, you can then start using digital modes.

6a) Dashboard view

Optionally, you can open the Pi-Star dashboard on any Windows, Mac, or Linux computer (not the hotspot) connected to the same network as the hotspot by browsing to (use trailing slash) http://pi-star/ for Windows, or http://pi-star.local/. Enabled modes are highlighted green, and you can monitor activity.

Pi-Star dashboard

Pi-Star dashboard Note: The dashboard is optional and takes a lot of bandwidth. If you have a metered data plan, you might want to run Pi-Star without it most of the time.
Hint: Click on a callsign to open the related QRZ page.
Note: If you enable YSF, P25, NXDN, or any of the cross modes, you'll see additional info displayed in the left column. (This image is for illustration purposes only. Normally, only one cross-mode network is enabled, for example, YSF2DMR, with the corresponding base cross-mode is disabled, in this example, DMR .)

6b) Admin view

To see more info, switch to the Admin view (requires authentication).

Info and manager modules – The upper portion of Admin view shows Gateway Hardware Info and Service Status, as well as D-STAR and BrandMeister Info and Manager modules.

Pi-Star Admin console - upper

Activity modules – The lower portion of Admin view displays activity modules.

Pi-Star Admin console - lower

6c) Live Logs view

From the Admin view, you can select the Live Logs view, which starts a more detailed live logging process that can be useful for troubleshooting. It can be helpful to open Live Logs view in a new tab or a different browser so you can look back and forth between the dashboard and the log.

There also are more specific logs you can check in the /var/log/pi-star directory, for example, there are specific logs for ircDDBGateway, MMDVM, etc. Thanks to Luis, CT1DVM, for pointing this out.

Hint: There's a link at the bottom of Live Logs view to download it as a text file. Key: D = Debug; M = Message; I = Info. See also: Pi-Star troubleshooting⩘ .

6d) Changing active modes

If you want to change which modes are active, open the Configuration view and in the MMDVMHost Configuration section, switch modes and cross modes on and off as wanted, and then apply changes.

MMDVMHost Configuration settings

7) Backing up and restoring Pi-Star

After you've done all the work of setting up Pi-Star just the way you want, it's a good idea to back it up. In Configuration view, click the Backup/Restore link.

Pi-Star Backup/Restore link

In the Backup/Restore view, click Download Configuration, and then choose a location to safely store your work so that if things ever get messed up you can easily restore your most recent working configuration.

Initiating a Pi-Star configuration backup or restore

8) Updating Pi-Star

Pi-Star update version
One of the nice things about Pi-Star is that it's updated on a regular basis to add new features, options, and fixes, as well as to add hostfile updates that have been pulled from upstream sources. There are three ways to update Pi-Star: one automated and two manual:

9) Upgrading Pi-Star

Pi-Star upgrade version
The less frequent Pi-Star version upgrades affect the base system services and packages. Both the update and upgrade processes automatically switch Pi-Star into Read-Write mode, so there's no need to switch manually.

  1. Use an app to SSH into Pi-Star and log in. Or you can use the Update and Upgrade links in the Expert Editor (see the following section).
  2. Begin with an update of the dashboard and binaries.
    In the SSH window:
    sudo pistar-update
    Or, click the Expert Editor's Update link.
    Allow the update process to run until you see:
    Updates complete, sleeping for a few seconds before making the disk Read-Only
    Finished
  3. Next, upgrade the operating system, services, and packages.
    In the SSH window:
    sudo pistar-upgrade
    Or, click the Expert Editor's Upgrade link.
  4. Run the upgrade process as many times as needed until the system reports you are on the most recent version:
    You are already running the latest version…
    Sleeping a few seconds before making the disk Read-Only…
    Finished
  5. It's a good idea to reboot the hotspot after upgrading.
    In the SSH windows:
    sudo reboot
    Or, open the Power view, and then click Reboot.
  6. The dashboard displays the current version number, for example, 3.4.16.

For more info about what's included in an upgrade: On the Pi-Star Downloads page⩘ , scroll down to the Change Log section.

10) Expert Editor: advanced Pi-Star configuration

If you are in Configuration view, you can click Expert to access the "Expert Editor," a set of advanced quick editors, full editors, and tools.

Pi-Star Expert Editor link

You'll be greeted by a **WARNING** message that you should pay attention to:

"Please keep in mind when making your edits here, that these config files can be updated by the dashboard, and that your edits can be over-written. It is assumed that you already know what you are doing editing the files by hand, and that you understand what parts of the files are maintained by the dashboard."

The Expert Editor provides access to:

[4] MMDVMHost DMR Network Jitter setting note: There's a good explanation about this by Andy Taylor in the Pi-Star User Forum (edited slightly for clarity): "Jitter is the difference in round trip times [pings] between two points…. It's quite normal for the answers from each ping to vary slightly, this can happen for a whole load of reasons, but it's the difference between those times that is the jitter: too large = slight delay on the start of a transmission, so slow, choppy audio and higher BER (potentially). For audio packets to give you the best performance, you need two things: low round trip time (lower is always better, it's a function of bandwidth and distance) and steady jitter. If the software knows that you are using a master with high jitter it will attempt to account for it."

10a) Updating hotspot firmware via Pi-Star

It's possible to update the firmware of several hotspot boards via Pi-Star, including the ZUMspot. See the note: Performing firmware updates via Pi-Star⩘ .

10b) Other advanced configuration notes

See Pi-Star notes⩘  for other advanced configuration notes, including:

11) Rebooting or shutting down Pi-Star

For a graceful way to reboot or shut down your hotspot, click the Power link.

Pi-Star Power link

In the Power view, click Reboot or Shutdown. Give your hotspot a minute or two to complete rebooting or shutting down.

Initiating a Pi-Star reboot or shutdown

Note: When you have a modem like the ZUMspot mounted on a Raspberry Pi, after Pi-Star shutdown is complete, the modem will continue to flash its mode lights (because power is still flowing through the shut down RPi to the modem) until you actually turn off the power to the RPi.

12) Pi-Star – Summary thoughts

I really like Pi-Star! It's my favorite hotspot software for the digital radio modes I use, D-STAR and DMR. It also handles YSF, and when used with an MMDVM-capable modem like the ZUMspot⩘ , even P25 and NXDN, as well as YSF and DMR cross modes.

12a) The dashboard is great

I'm actually surprised by how much I like the dashboard. I thought it would be a "nice-to-have" feature, but it turns out that it's great to be able to watch the activity on a reflector, especially during a net. It's also nice to be able to easily look up people's linked pages, usually their QRZ page.

12b) Actively developed and supported

Another thing I really appreciate is how actively and enthusiastically Andy Taylor and team are developing and supporting Pi-Star. Improvements and new features are added on a regular basis, including all the latest cutting edge innovations, and they listen attentively to the feature requests from the community of Pi-Star users.

12c) Works great in the shack and on the road

Paired with a compact hotspot, Pi-Star is a great solution for use both as a base station and as a mobile hotspot. See: Connecting Pi-Star via cell phone⩘ .

Minimalist ZUMspot mobile hotspot

12d) Worth supporting!

Obviously, Andy, MWØMWZ, and team—including Adrian, MØGLJ, Craig, W1MSG, and Andrew, M1DNS—are pouring a lot of effort and intelligence into creating and supporting Pi-Star, which they're giving away freely to digital hams. There's also a robust community of hams contributing to helping Pi-Star users via the Pi-Star User Forum and Support Group⩘ . Per Andy:

And now to you dear reader, you are probably reading this because you already run Pi-Star, or you are about to start. Without you, this project wouldn't be where it is today, a shining beacon of what can be when a few like-minded people with similar interests are prepared to set monetary gain aside and just give away their work. You might not be a coder, you might not feel that you understand digital radio enough to give anything back, but that time will come. Enjoy the hobby, tell your friends what we got right with Pi-Star, and tell us when it does something it shouldn't.

Thanks for creating a really nice solution, Andy and team!

If you end up appreciating Pi-Star as much as I do, consider supporting this work by contributing to the Pi-Star User Forum⩘  or the Support Group⩘ , or by sending some monetary support their way toward the costs of the equipment they're using to make Pi-Star so great.
