Pi-Star (MMDVM)

General instructions on how to setup a RF Based MMDVM Hotspot using Pi-Star using MMDVMHost Mode to a BrandMeister Server. This is assuming a new hotspot being configured.

Please make sure you have updated and are on the latest version of Pi-Star software. By doing so will make it easier to provide support by both of the support teams (Pi-Star and Brandmeister).

Setup your Pi-Star Configuration

1.) Start by opening your preferred web browser and enter http://pi-star.local or http://pi-star or the IP address of the hotspot if you know it. You will be then presented with the following page (Dashboard). It is assumed you have already setup your Wi-Fi configurations and will not be discussed in this setup step by step you can refer to a helpful website for detailed setup - Amateur Radio Notes: Pi-Star.

Notice we indicate after each section/step to click on the "Apply Changes". This is important to do as this will setup the Pi-Star software to allow for the next steps to be performed. Some will not display until a previous step/action is applied to the Pi-Star Software.

2.) Next click on "Configuration" link at the top right of the dashboard. This will take you to the configuration options for the Pi-Star Software/Hotspot.

3.) In the Control Software section is where you can set the type of Controller Mode the hotspot will operate as, either simplex or duplex. Select the best choice related to the type of MMDVM board you are using and then click save if needing to change to Duplex as Simplex is the default setting or can skip clicking apply since it is defaulted to Simplex and move to the next step.

4.) Next we will need to enable the DMR Mode under the MMDVMHost Configuration section by click on the toggle switch next to DMR Mode. Click "Apply Changes" and wait for the Pi-Star software to restart and enable the option. Don't worry about the other options here. You are more than welcome to explore the other modes to enable but for this setup we will only focus on DMR and connecting to a BrandMeister Server.

5.) Next scroll down to the General Configuration section and enter in the following information below. The ones mentioned are those for recommended to ensure there is a value set.

  • Node Callsign: - This is your Amateur Radio Call Sign. Only enter your call sign here.

  • CSS7/DMR ID: - This is your 7-digit ID which was issued to you from RadioID.net. If you need to get one click here on getting a 7-digit ID from RadioID.net.

  • Radio Frequency: Enter the simplex frequency here. If you have a duplex an additional box will be present to provide RX and TX frequencies (this is only shown if in duplex mode).

  • Latitude: - You can leave this as is or enter your Latitude.

  • Longitude: - You can leave this as is or enter your Longitude.

  • Town: Enter your City/Town.

  • Country: Enter Your Country

  • Radio/Modem Type: Choose the modem you are using. Refer to the vendor/manufacture you obtained your device from.

  • Node Type: Choose private if you are only using this hotspot yourself and not sharing with any other users. Your 7-digit ID you entered in the CSS7/DMR ID must match to the radio. If you have more than one 7-digit ID and want to allow access then choose Public.

  • DMR Access List: If you selected Public in the Node Type then enter in the 7-digit Radio IDs you wish to be able to use your hotspot using a comma to separate each one. For Example: 1234567, 2345678, 3456789. If you have chosen Private than this box wont allow you enter and can leave it blank.

  • APRS Host Enable: Leave this as default (off)

  • APRS Host: Leave this as default (rotate.aprs2.net)

  • System Time Zone: Select your time zone from the drop down.

  • Dashboard Language: Choose your preferred language.

When completed make sure you click on "Apply Changes" so the changes are saved. This will take a few moments and will return you to the configuration page when done.

6.) Next scroll down to the DMR Configuration section and enter the following information.

  • DMR Master: Select the BrandMeister Server of choice. In this example we will use BM 3103 United States.

  • BM Hotspot Security: Enter your Hotspot Security Password you entered in on BrandMeister Selfcare for the Radio ID used for the hotspot. Click here to setup a hotspot security password if you have not done so.

  • BrandMeister Network ESSID (or might see DMR ESSID): This allows you to select an alias for the hotspot. For your first hotspot you can choose 01 or leave as none. If you plan to have more than one hotspot then you should select 01 or any number from 01 to 99. Each hotspot must have a unique ID and ESSIDs allow for this work properly on the network.

  • DMR Color Code: Choose your desired Color Code for the hotspot.

Finally click on "Apply Changes" and wait for the Pi-Software to restart and enable the configurations.

You are probably asking why can't I use DMRGateway as an option? You are more than welcome to use it but take note BrandMeister Support team will not provide support for those who use DMRGateway as it can be complex and may have many options for configuration. We recommend referring to the Pi-Star Support options for a list of sources if you choose to use DMRGateway for support on configuration and other issues you may run into.

7.) Finally click on the Dashboard Link at the top navigation of the hotspot to show the dashboard. Take notice on the left side indicators. If all has gone according to plan and followed the setups in this document you should see a Green DMR Net under the Network Status. It means you are ready to operate your hotspot with your DMR Radio.

If you see a yellow DMR Net, this indicates the hotspot is not connecting and can be one of many issues listed below:

If you see a red DMR Net it means some other configuration is not set properly.

8.) Congratulations on reaching this step, If you got a green DMR Net indicator you are done. You can now operate your hotspot on BrandMeister using your DMR Radio. Enjoy!
