Configuration File Location

The systemd configuration files for AMBEserver are located in /etc/opendv

cd /etc/opendv
ls -1
ambeserver-ttyAMA0.conf
ambeserver-ttyS0.conf
ambeserver-ttyUSB0.conf

If your device is at a different location, e.g. /dev/ttyUSB1 simply copy the similar file and give it a new name with the new device

sudo cp ambeserver-ttyUSB0.conf ambeserver-ttyUSB1.conf

Modifying the Configuration File

Use an editor like vi or nano to edit your configuration file

sudo nano /etc/opendv/ambeserver-ttyUSB0.conf

There are two environment variables that may be modified namely UDP_PORT and AMBESERVER_FLAGS

Here are the contents of the configuration file:

# # Configuration file for the AMBEserver program started by systemd. # Adding flags to AMBESERVER_FLAGS will pass this to the daemon. # For example, to change the speed to 460800, use the following line: #

# 아래 두가지만 확인

AMBESERVER_FLAGS="-s 460800"

UDP_PORT=2460 ; 2465로도 설정해도 되나 DVSwitch 혹은 BlueDV에서 설정 시 같은 값을 설정하여야 함

 

AMBESERVER_FLAGS=""

 

For example, on the newer ThumbDV™ (Rev. A) you would modify the AMBESERVER_FLAGS variable

AMBESERVER_FLAGS="-s 460800"

To have AMBEserver listen on another UDP port, which is useful if you have more than one AMBEserver running on a single Raspberry Pi -- each with its own AMBE device.

UDP_PORT=18307

Managing the AMBEserver

The commands for checking, starting, stopping, enabling, and disabling the AMBEserver are as follows:

sudo systemctl status ambeserver@ttyUSB0.service sudo systemctl start ambeserver@ttyUSB0.service sudo systemctl stop ambeserver@ttyUSB0.service sudo systemctl enable ambeserver@ttyUSB0.service sudo systemctl disable ambeserver@ttyUSB0.service

Modify the tty service name as appropriate by replacing ttyUSB0 with:

• ttyAMA0 for a PiDV™ on on Raspberry Pi / Raspberry Pi 2
• ttyS0 for a PiDV™ on the Raspberry Pi 3
• ttyUSBx where x is a digit for the ThumbDV™ on all Linux based systems

Enabling the service will allow the AMBEserver to automatically restart when the Raspberry Pi is restarted.

Testing the AMBEserver

Login to https://nw-digital-radio.groups.io/g/ambe and download ambesocketest.py from the file section. 

Execute the script

python ambesocketest.py

If the script returns (repeatedly):
Server reply : a
                        0AMBE3000R

You have an operating AMBEserver. Use control-C to escape/kill the test.

Accessing AMBEserver 

DummyRepeater for Windows or Linux

Under Compass Linux DummyRepeater can be installed with

sudo apt-get install dummyrepeater

Under Preferences. 

Use address 127.0.0.1 if DummyRepeater is running on the same computer, or the IP address of the computer where AMBEserver is running.

Buster for MacOS

Under Preferences

Use address 127.0.0.1 if Buster is running on the same computer, or the IP address of the computer where AMBEserver is running.

 

Over the Internet

See blog post at NW Digital Radio

 

Quick Build on Linux

These files are also in the files section.

If you cannot find an AMBEserver package for your architecture and distribution. Try this:

wget https://raw.githubusercontent.com/dl5di/OpenDV/master/DummyRepeater/DV3000/AMBEserver.c
gcc -o AMBEserver AMBEserver.c

Place the executable in an appropriate place, and create configuration and autostart files.  On Raspbian/Debian this would be
sudo cp AMBEserver /usr/sbin

If using the files from ambesupport.tgz (below) /usr/sbin is expected.

 

A set of files for systemd management are located in the files section: ambesupport.tgz

Download this file to the target computer's filesystem and run 
# these files expect that an opendv user exists
sudo useradd -s /bin/false opendv && sudo usermod -G dialout opendv
mv ambesupport.tgz /tmp &&  cd / && sudo tar -xzvf /tmp/ambesupport.tgz
Use the above instructions to manage the server.

DVSwitch Server에서 AMBE Server를 연결하여 사용 시 반드시 Server 두대 모두 유선 LAN 선으로 연결하세요

그렇지 않으면 끊어짐 / 지연 문제로 사용할 수 없습니다
