Direwolf 1.6 Official release

Today is the Official release of Direwolf 1.6 (29 Oct 2020)

I’ve been running the “Dev” version of Direwolf for a while. 1.6D. But now I read this morning that John WB2OSZ has made version 1.6 official after 2 years. Version 1.5 was released on 8 Oct 2018

I read in the mail that there is almost no difference with the “Dev” branch. So I don’t really see any need to install the official release.



New Build Procedure:

* Rather than trying to keep a bunch of different platform specific Makefiles in sync, "cmake" is now used for greater portability and easier maintenance.

* README.md has a quick summary of the process. More details in the *User Guide*.

New Features:

* "-X" option enables FX.25 transmission. FX.25 reception is always enabled so you don't need to do anything special. "What is FX.25?" you might ask. It is forward error correction (FEC) added in a way that is completely compatible with an ordinary AX.25 frame. See new document *AX25_plus_FEC_equals_FX25.pdf* for details.

* Receive AIS location data from ships. Enable by using "-B AIS" command line option or "MODEM AIS" in the configuration file. AIS NMEA sentences are encapsulated in APRS user-defined data with a "{DA" prefix. This uses 9600 bps so you need to use wide band audio, not what comes out of the speaker. There is also a "-A" option to generate APRS Object Reports.

* Receive Emergency Alert System (EAS) Specific Area Message Encoding (SAME). Enable by using "-B EAS" command line option or "MODEM EAS" in the configuration file. EAS SAME messages are encapsulated in APRS user-defined data with a "{DE" prefix. This uses low speed AFSK so speaker output is fine.

* "-t" option now accepts more values to accommodate inconsistent handling of text color control codes by different terminal emulators. The default, 1, should work with most modern terminal types. If the colors are not right, try "-t 9" to see the result of the different choices and pick the best one. If none of them look right, file a bug report and specify: operating system version (e.g. Raspbian Buster), terminal emulator type and version (e.g. LXTerminal 0.3.2). Include a screen capture.

* "-g" option to force G3RUH mode for lower speeds where a different modem type may be the default.

* 2400 bps compatibility with MFJ-2400. See *2400-4800-PSK-for-APRS-Packet-Radio.pdf* for details

* "atest -h" will display the frame in hexadecimal for closer inspection.

* Add support for Multi-GNSS NMEA sentences.

Install/compile instructions

### Linux - Using git clone (recommended) ###

***Note that this has changed for version 1.6.  There are now a couple extra steps.***

First you will need to install some software development packages using different commands depending on your flavor of Linux.
In most cases, the first few  will already be there and the package installer will tell you that installation is not necessary.

On Debian / Ubuntu / Raspbian / Raspberry Pi OS:

    sudo apt-get install git
    sudo apt-get install gcc
    sudo apt-get install g++
    sudo apt-get install make
    sudo apt-get install cmake
    sudo apt-get install libasound2-dev
    sudo apt-get install libudev-dev

Or on Red Hat / Fedora / CentOS:

	sudo yum install git
	sudo yum install gcc
	sudo yum install gcc-c++
	sudo yum install make
    sudo yum install alsa-lib-devel
    sudo yum install libudev-devel

CentOS 6 & 7 currently have cmake 2.8 but we need 3.1 or later.
First you need to enable the EPEL repository.  Add a symlink if you don't already have the older version and want to type cmake rather than cmake3.

    sudo yum install epel-release
	sudo rpm -e cmake
	sudo yum install cmake3
	sudo ln -s /usr/bin/cmake3 /usr/bin/cmake

Then on any flavor of Linux:

	cd ~
	git clone https://www.github.com/wb2osz/direwolf
	cd direwolf
    git checkout dev
	mkdir build && cd build
	cmake ..
	make -j4
	sudo make install
	make install-conf

This gives you the latest development version.  Leave out the "git checkout dev" to get the most recent stable release.

For more details see the **User Guide** in the [**doc** directory](https://github.com/wb2osz/direwolf/tree/master/doc).  Special considerations for the Raspberry Pi are found in **Raspberry-Pi-APRS.pdf**

  1. Hi Eduardo,
    You are absolutely right. RX is always active for FX.25 but if you want to use TX, both sides have to activate it. If you give -X 16 or -X 32 or -X 64 as start option you can use FX.25. This stands for 16, 32 or 64 check bytes. Both sides must specify the same value when starting Direwolf.

  2. What is the best way to get Direwolf hooked up with JNOS2? I’m trying to avoid using any kind of kernel ax25 but nothing I use in the JNOS2 attach seems to work.
    Still requires some kind of SOCAT connector?

    Thanks & 73,

  3. I have been playing with some of these https://maxonamerica.com/product/maxon-sd-670d-series-data-radios/
    DMR data radios with a ttl or a usb serial interface. The modem are dumb, just transmit and receive at 9600 baud over the air. I am using the DMR all call as the group contact. I am wanting to add units as digipeaters. Is there a way to get full x.25 out of direwolf on a serial port? The DMR modems have no way of digipeating or store and forward. Here is the concept

    direwolf (x.25 over serial)—DMR RF modem—DMR rf modem (with direwolf doing digipeat)– DMR modem–direwolf.
    By using ax.25 as the routing protocol I can have a wide area packet network with multiple digipeaters over a simplex narrowband DMR channel at 9600 baud over the air.
