Overview

The DV-MEGA is a family of add-on boards (shields) for Arduino Uno, Arduino MEGA and Raspberry Pi for several digital voice communication standards.
DV-MEGA is produced by Guus van Dooren PE1PLM, http://www.dvmega.auria.nl/

The single band (UHF) versoin Dvmega sb.jpg

Currently supported are the following DV modes:

  • D-Star
  • DMR+
  • DMR BrandMeister


To communicate via such a hotspot, a transceiver capable of the used DV mode is necessary to operate, the hotspot provides only an access gateway to the selected infrastructure. The DV-MEGA has only one time slot.

Functionality

  • Private call
  • Group call

Soon

  • SMS
  • GPS
  • RRS/ARS

Mode of work

  • DVMEGA + Raspberry PI + the MMDVMhost application
  • DVMEGA + Raspberry PI + the BlueDV application for Android via ser2net in a hotspot mode wifi connection
  • DVMEGA + Bluestack board + BlueDV application for Android via Bluetooth

Hardware

Three different hardware configurations of DV-MEGA are currently available:

  • Dualband radioshield - Arduino UNO based Support for D-Star and DMR
  • Dualband radioshield - Arduino MEGA based Support for D-Star and DMR
  • RPi radioshield - Raspberry PI based Support for D-Star and DMR
  • RPi radioshield - Orange Pi based Support for D-Star and DMR

Software

  • dmrlib (highly experimental, for developers only)
  • BlueDV [1]
  • BlueSpot [2]
  • MMDVMHost [3]

  • easyBM [4] A lightweight Image with an webbased configuration tool.
  • easy-DVMega [5] is a raspbian Jessie image with a complete configuration to be used on a Raspberry Pi with the DVMEGA shield.
  • 20160505_R2AJV-raspbian-jessie_lite-VNC-LXDE-DVMEGA_MMDVMHost - the image based on Raspbian Jessie Lite to build a hotspot nodes D-Star and DMR using the MMDVMHost application. Requires 4GB or more SD card. Login pi, password raspberry, VNC port 5901.
