Release DVPI Version 1.03 (scirpt update)

Posted: 12 Jul 2021 10:54 PM PDT http://www.hamskey.com/2021/07/release-dvpi-version-103-scirpt-update.html

Release DVPI Version 1.03
There have been some changes to the DMR node recently.
This version changes only those related to the recently changed DMR node.
If you normally use Version 1.0 or Version 0.95, no upgrade is required.
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
https://github.com/phdlee/dvpi/releases/tag/v1.03 https://github.com/phdlee/dvpi/releases/download/v1.03/dvpi_103.zip

https://github.com/phdlee/dvpi/releases/download/v1.03/dvpimanager_103.zip




2.What was added in Version 1.03 (from Version 1.0)
-To reduce user confusion, the MMDVM password change function has been removed.
If the DMR's BM password has been changed, it can be changed on the
DVSwitch Settings Change screen.
- It is not a function you use. Changed the TX/RX frequency of MMDVM to the same frequency. This is because the new DMR rule may not work if the
frequency is different.




3.How to Install
There is a detailed explanation about more detailed installation method
and H/W configuration on my blog.
The following explains how to download and configure to use DVPi. Please refer to another post for more details.


3.1 Download
Download the dvpi_103.zip and dvpimanager_103.zip files from the download link.

Unzip the downloaded files (dvpi_103.zip, dvpimanager_103.zip)


3.2 Write the dvpi_103.img file to the SD card.
Formatting the SD card is not mandatory. When I apply the image file to
the SD card, sometimes an error occurs, so I format it first.


Apply the dvpi_103.img file to the SD card with Win32Disk Imager.






After completion, remove the SD card and insert it into the Raspberry Pi of
the DVPi.

Connect power to the DVPi. (power on DVPi)

Sometimes, depending on the LCD, the screen is turned upside down, You can reverse the top and bottom of the screen in DVPi Manager.


At the time of the first boot, because there is no setting, it is not
possible to log in.


3.3 Find DVPi IP AddressThe Raspberry Pi image used in DVPi is
automatically assigned an IP (using DHCP Server).You can use the DVPi
Manager to find out the IP of the DVPi.

Run DVPi Manager -> Click the 'Find DVPi' Button

Click the 'Find' Button(If multiple LAN cards are installed in your
computer, you must select the IP address of your computer before clicking
the 'Find' button)
I have 3 DVPi and they are all found. Once you have found the IP of the
DVPi you can use ssh.DVPi can be accessed with ssh id: pi, password: dvpi

3.4 Installing DVSwitch and Setting up DVSwitch(DVSwitch installation is
only necessary to embed DVSwitch into DVPi)
Execute DVPi Manager -> Input DVPi IP Address -> Click the 'Connect' Button Click the 'Easy setup of installed DV Switch'


To embed DVSwitch into DVPi, you only need to execute 4 commands. The four commands are explained in the center of the screen.

Rutn the SSH Client as puttyLogin ID : pi, Passwor d: dvpi


Execute the commands described in DVPi Manager one by one.It is convenient
to use copy and paste.

In the case of putty, you can copy and paste multiple lines at once.




Execute 'sudo apt-get install -y dvswitch'


If all 4 commands were executed, your DVPi would have DVSwitch installed.Setting up DVSwitch is easy with just a few entries.

Enter your callsign and DMR ID,Unique ID is your Hotspot number that is
unique. Any number you don't use is fine.

Choose Brand Meister Host, It is recommended to choose a server in your country.(The US1 server that was set as the default until DVPi Version 1.0
is no longer operated)

If you have changed your password in Brand Meister, you must change the password field to your password.

The BM password can be changed here.

Enter the changed password.
Enter the Location field, the rest is not required, but it is strongly recommended to enter latitude and longitude.Click the 'Apply All Setting' button.

The screen below is displayed and the operation takes about 1 minute.

When all settings are completed, the following message is displayed.

After rebooting DVPi, you should be connected to the DVSwitch server as
shown below.



You can also check your Hotspot list if you log in to Brand Meister. I set
the unique number 37 and it was displayed as follows.


3.5 flip the screen upside down(This is only necessary if the screen is
upside down like me. If your screen appears normally, this step is not necessary.)
Click the 'DVPi Basic Setup'

Click the '3.5 LCD 180 (upside down)' Button click



After rebooting, it will display normally as shown below.


3.6 Using DVPi(For detailed usage and hardware configuration, please refer
to other posts)
I will configure the DVPi to Dual Mode. Since it's in Single Mode now,
only VFOA works.Since VFOB copies the settings of VFOA as it is, it is necessary to test whether VFOA works well.
Change TG


Reception is good. You have to test the transmission. If you are using
D-Star, I recommend testing up to D-Star.


3.7 Dual Mode Settings
Connect to DVPi via SSH Client


Execute the setdvs2.sh command. (./setdvs2.sh new unique number, The
unique number is the new Hotspot number. ex ./setdvs2.sh 38)

You can ignore the following error messages during script execution. (This
is because it is a command to delete if it is already installed)

When all execution is completed, it asks if you want to reboot as
follows.No reboot required. This is because DVPi Manager will cause the
DVPi to reboot.

Run DVPI manager

Click the 'DVPi Basic Setup'

After selecting Dual VFO as shown below, click the 'Apply All Setting' button.(You may select 'Use Voice' if you wish to use the voice guidance function of DVPi)

When all settings are completed, DVPi automatically reboots.

After rebooting, DVPi operates in Dual Mode.

How to use DVPi's Dual Mode is described in detail in another post.



I tried changing the TG of VFO B.


3.8 DVPi's Hardware SettingsDVPi does not require any hardware other than
the Raspberry Pi, sound card and LCD.But for convenience, you can add
things like buttons that you need.How to add hardware to the DVPi is
detailed in another post.
Run DVPi Manager

Click the 'Settings to use rotary encoder, PTT, and VOX functions' Button

In my case, I chose all of the below because I had a rotary encoder and buttons.(If the direction of the rotary encoder is opposite, the numbers in
the red square box below are interchanged)

When the activation selection for hardware is finished, click the 'Apply
All Setting' button.


If the DVPi is equipped with a rotary encoder, it is possible to check who
is in the TG as shown below.


4. conclusion

DVPi has quite a few features. In this post, I only set the settings for
some of the features that are absolutely necessary for me.
You can find various features in different posts.
