Release DVPI Version 1.0


Release DVPI Version 1.0

Version 1.0 and Version 0.95 are the same. If you are using Version 0.95 you do not need to update to Version 1.0. 

DVPiManager has some features added. If you want to use features added in Versio 1.0, you only need to download dvpimanager.

DVPi uses the USRP Client protocol. When you install and use DVSwitch, you must read and comply with the license that appears. The user is responsible for the license for the use of DVPi.

1.Download Link

2.What was added in Version 1.0 (from Version 0.95)

2.1 DVPi Manager 1.0 has added the ability to change the DMR password.

  Of course, you can change the DMR password using the DVSwitch Setup function in DVPiManager. But it will be a pretty long process.

If you have changed the DMR password in, you can easily change the DMR password in DVPiManager.

Enter the password you changed at brandmeister in the password field.

If you are using DVPi in DualMode, select both MMDVM_Bridge#1 and MMDVM_Bridge#2. If not, just choose MMDVM_Bridge#1.

Then click the'Change Password' button. Restart DVPi and your new password will take effect.

2.2 DVPi update function

If you are using DVPi 0.95 you do not need to update to Version 1.0. Just download DVPiManager 1.0.

But if you want your DVPi to appear as Version 1.0, click the Update button.

It automatically downloads and updates DVPi executable files from the web.

When all updates have been completed, the following message is displayed.

If you restart DVPi, Version 1.0 will be displayed. 

If the update fails, you can download the DVPi executable file below.

3. Getting started with DVPi

Posts on DVPi :

DVPi works without additional circuitry. You can configure additional circuits when you want to be more convenient.

Thank you for using DVPi.

Next time, I'll post a new kind of article.



  1. Hi Lan, I would like to know if the dvpi sources are available to implement other functions (ysf, m17 etc.) in this way also other OMs can participate in the project.

    1. My dvpi V1.0 has stopped working it will no longer connect to brandmiester network , is there a solution as to why it has stopped working today , even after a fresh install on a new Sdcard and full setup it will not appear as a hotspot connected to brandmiester what am i doing wrong as it was fully functional up untill today?

    2. See my comments below about making the TX and RX frequency the same. Had the same problem and that fixed it for me.

    3. A DVPI does not use RF so how on earth do you change the TX RX frequency please explain where? how? And what file? To edit to change what you mention , there is no RF board it’s all software based so what are you editing to make it work again?

      Please explain in detail thanks

  2. Happy New Year 2021, Prof. Lee!

    Thanks for DVPi V1.0 Release and your effort!

    See you~~

  3. Hi IAN, just some suggestions and questions about last release and future develop:

    1) It will be nice to add on setup menu a tabtext where to change or modify the Talker Alias. BM admin do not like Talker alias with callsign plus dvpi or dvswicth or ....

    2) I did a test on record QSO but I was not abale to download it. May be I did something wrong.

    3) Changing from DMR and D-star the vlume adjust is not the same. It is on the road map do fix it ?

    For the rest this system it working in a very good manner. people do not see difference from a DMR rig and this system

  4. This is a beautiful project, there are many potentialities in this software but they are not exploited, the dvswitch server communicates with the clients with scripts, this project lacks the possibility of having empty buttons to customize so that each OM can insert the functions to be sent to the dvswitch server via script, an example could be the possibility of sending "./ mode" followed by the way you want to activate dmr, ysf, p25 etc. to switch the server, I tried to do it from the terminal and it works.

    I hope Lan releases the sources so we can work on them.


  5. I would like to add the DMR TG for East Coast Reflector 3127793 to the DVPI. I see there is a Sample1 set of TGs that I will not use. Where is the data file for the Sample1 (70403. 70404 etc) file to I can edit it to include 3127793? Thanks for the nice project.

    1. you can do it from DVPI Manager, "Talk group list editor"

  6. Well, really good work!
    I suggest a couple of additions to the project: first of all, the Bluetooth activation for audio i/o as an alternative to the USB stick! And then, the addition also in D-Star mode, of a status bar with the list of the last REF selected (and why not also another status bar that lists the XREF?).

  7. Hi. Is there some way to set ot toggle the PTT from the Raspbian bash shell?
    Thanks for the great job.

  8. I was wondering if the development of this project will continue because it is currently a job left halfway through not being able to select other digital modes and not having the sources available to study and apply updates.


  9. My DVpI no longer connects to the server, it was surely connected with the one that caught fire. Do you have information on how to replace the IP address and direct it to another server?
    We hope Lan KD8CEC read this post and can reply !!
    Hello everyone I3YBD Maurizio

  10. BM is implementing controls to disallow mis-configured hotspots from connecting to their network. Some of our early configurations violate this and cause a connection to not complete. Here is what you need to check:
    in /opt/MMDVM_Bridge/MMDVM_Bridge.ini



    Make sure your RX Frequency matches your TX frequency and that your callsign is correct for your DMRID+SSID


    1. Hi i cant seem to save


      As i am not root user ? How do i do it ?

      Thanks MM6NRK

    2. Once you are in the /opt/MMDVM_Bridge/ folder, type sudo nano MMDVM_Bridge.ini, make your changes, and then follow the prompts to save and exit nano.

  11. Thanks. Making the RX and TX FREQs the same fixed it.

  12. Salve quando lancio i comandi tramite Putty al terzo comando mi viene fuori questa scritta:
    " sudo ./install-dvswitch-repo
    This script is no longer used
    Please use the buster script
    chmod +x buster
    apt update
    You can now install dvswitch programs"

    per cui poi non installa Dvswitch.
    e non so come andare avanti mia esperienza con sistemi linux è molto scarsa.

    1. 1° comando wget
      2° comando chmod + x buster
      3° comando ./ buster
      4° comando apt update

    2. This comment has been removed by the author.

  13. ok ho fatto come hai detto e tutto ok ma non si registra. Ho editato il file MMDVM_Bridge.ini e modificato freq. per metterle uguali ma niente su BM lo strano è che vedo il passaggio su "TG222" "ma non ricevo niente da nessun TG... sempre NOINFO e UNREG.
    La PSW è giusta è la stessa dell'HS, a settembre avevo già fatto una prova con DVPi 0.88 ed era tutto ok.
    Poi aspettavo i pezzi per implementare l'encoder e i pulsanti, un po' di problemi sanitari mio avevano fermato.
    Ora mi ci sono rimesso ma non riesco a venirne a capo. la cosa positiva e che mi sto impratichendo (in forma minimale) a Linux.

    parte iniziale del mio MMDVM_Bridge.ini

    "Callsign = IU1NXV
    Id = 222583857
    Timeout = 180
    Duplex = 0

    RXFrequency = 224940000
    TXFrequency = 224940000
    Power = 1
    Latitude = 44.159912
    Longitude = 8.28196
    Height = 0
    Location = Pietra Ligure, ITALIA
    Description = DVPi with DVSwitch
    URL = / db / IU1NXV
    Per inciso ho attivato solo DMR per non mettere casino su casino.

    Grazie Danilo IUNXV

    1. Hai editato il file analog_bridge a volte il dvpi manager scrive cavolate
      iz7exi se vuoi scrivimi in privato su trovi la mia mail

    2. I have exactly the same problem. CX9CPE. Pablo

    3. i think the problem is that we are banned by the Brandmeister System.

  14. Will this version work on a raspberry PI Zero W?

  15. Hi, the following commands are not responding,

    chmod +x install-dvswitch-repo
    sudo ./install-dvswitch-repo
    sudo apt-get install -y dvswitch

    is there any solution?

    1. some post is written above

    2. Still not working, the commands should not be well written or should not work

    3. I have tried the following and it doesn't work

      1° comando wget
      2° comando chmod + x buster
      3° comando ./ buster
      4° comando apt update

  16. 1 ° comando wget
    2 ° comando chmod + x buster
    3 ° comando ./ buster
    4 ° comando apt update

Release CEC Firmware v1.200 for uBITX All version(include V2, V3, V4, V5)

Release CEC Firmware v1.200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now. I received the feedback from a thankful beta tester and tested it myself by converting my uBITX v3 to v5 but I was not sure. I ordered the uBITX V5 and delivered the correct uBITX V5, so I made a little more fine-tuning. If you use V2, V3, V4, you do not need to update this firmware.
