DV4 Mini

Typical running images...

link for Quad core raspberry pi software..
NOTE! this will NOT run on a single core variant. (tried and failed :-(  ) check out how many onscreen raspberry's on boot up!)
Also, a firmware update to v1.61 or v1.64 maybe a good idea also! (files at the bottom of page, if you don't have it, ready to flash!)
you can check version running on your stick at the top of the program window once the main Dv4 software is running.

download link!

...Warning This file is large! 2.0gb

This zip file needs extracting, it contains the .img and instructions (PDF) in german. All credits to DG9FFM for his Efforts.
if you are going to use the network socket on the pi for internet, then you are ready to go, else you need to set up pi wifi dongle initially.

you need a blank 8gb tf card class 6 or faster, and win32 diskimager software (download zipfile below) to write image file to blank tf card.

After this is written, insert card on raspberry pi, and it should all autostart.

You will need to set software first time round, id number, locator, ect

If pi is repowered for any reason it will default to your settings.

Latest Firmware v1.73! with new software..  10/11/16

Firmware 1.73  now adds DPMR mode.

The support for DPlus REF Reflectors is updated, this fixes dropout problems. The quality of data coming from DPlus reflectors is measured and displayed since we found that about 2 to 3% of all voice frames are missing. These missing frames are replaced with silence frames.

Remember.., if you loose the dongle and the hardware dosen't see it. There's a link on the dongle board that can be shorted, as in the manual to force the bootloader to become active. Allowing you  to then program the firmware...

Raspberry pi tip!

Here i run the dv4dongle on raspberrypi2. Without any video, keyboard, or mouse involved. If the power drops, on repowering the rpi will autostart the DV4mini dongle!!

Here's how.

Firstly make sure that the dv4mini is working ok on raspberry pi

frequency, reflector, call ,ect.

load up file manager from main menu. and check the hidden files box from view menu.  Now look for .config folder.

Inside this folder  make new folder called AUTOSTART.  Then from the main desktop, drag ur dv4mini start up icon into the newly created AUTOSTART folder. All done!

So when you restart raspberry pi. with power lead,dongle and either network lead or wifi dongle it will boot up and boot dv4mini software and run happily on its own!

The new v1.73s/w is able to utilise cheap chinese dpmr handsets is great,( with fusion style rooms, with echo facility on reflector 99)

Also the new software has an adjustment feature.

first (very important! ) Disconnect dv4mini   from any reflector that maybe in use.

goto expert settings, key radio and under
qrg rx/tx settings you will now see a bar showing link data quality. the qrg rx/tx dropdown menu can now be adjusted for lowest errors!

The zip files are at bottom of page. (DV4_v1.6x) contains both the pc software installer and the firmware for the dv4mini stick.


setup a channel! usually a spare one...

set ur channel info simular to this. if you can set your power to low.

then add to your chosen zone.
my case looked for gb7ns and clicked and added!
the result is then scribbled to the radio.

New! 10/12/2015
brandmeister servers... all change!

windows 7!
edit ur pc at c:\windows\system32\drivers\etc
and edit ur HOST file, with admin priveliges on notepad (right click!) before starting,
on the hosts file right click and untick read only.

at the bottom of host file add:
then save without file extension (all files NOT .txt)
reboot and start dv4mini software, then select a new master!!
there u go ,all ready to go.

all simular with raspberry pi also!!
