|
|
|
|
- In Mac OSX version: Assertion failed: (adev[a].inbuf_size_in_bytes >= 100 && adev[a].inbuf_size_in_bytes <= 32768), function audio_get, file audio_portaudio.c, line 917.

|
|
|
|
- Enhancements to APRStt gateway including Morse code and speech responses to to APRStt tone sequences.
|
|
|
|
- Preliminary support for Mac OS X. NEEDS MORE TESTING!
|
|
|
|
- A list of all symbols available can be obtained with the -S
|
|
command line option.
|
|
|
|
- APRS Telemetry Toolkit (incomplete).
|
|
|
|
----------
|
|
|
|
## Version 1.2 -- June 2015 ##
|
|
|
|
### New Features ###
|
|
|
|
- Improved decoder performance.
|
|
Over 1000 error-free frames decoded from WA8LMF TNC Test CD.
|
|
See "A-Better-APRS-Packet-Demodulator.pdf" for details.
|
|
|
|
- Up to 3 soundcards and 6 radio channels can be handled at the same time.
|
|
|
|
- New framework for applications which listen for Touch Tone commands
|
|
and respond with voice. A sample calculator application is included
|
|
as a starting point for building more interesting applications.
|
|
For example, if it hears the DTMF sequence "2*3*4#" it will respond
|
|
with the spoken words "Twenty Four."
|
|
|
|
- Reduced latency for transfers to/from soundcards.
|
|
|
|
- More accurate transmit PTT timing.
|
|
|
|
- Packet filtering for digipeater and IGate.
|
|
|
|
- New command line -q (quiet) option to suppress some types of output.
|
|
|
|
- Attempted fixing of corrupted bits now works for 9600 baud.
|
|
|
|
- Implemented AGW network protocol 'y' message so applications can
|
|
throttle generation of packets when sending a large file.
|
|
|
|
- When using serial port RTS/DTR to activate transmitter, the two
|
|
control lines can now be driven with opposite polarity as required
|
|
by some interfaces.
|
|
|
|
- Data Carrier Detect (DCD) can be sent to an output line (just
|
|
like PTT) to activate a carrier detect light.
|
|
|
|
- Linux "man" pages for on-line documentation.
|
|
|
|
- AGWPORT and KISSPORT can be set to 0 to disable the interfaces.
|
|
|
|
- APRStt gateway enhancements: MGRS/USNG coordinates, new APRStt3
|
|
format call, satellite grid squares.
|
|
|
|
|
|
### Bugs fixed ###
|
|
|
|
- Fixed "gen_packets" so it now handles user-specified messages correctly.
|
|
|
|
- Under some circumstances PTT would be held on long after the transmit
|
|
audio was finished.
|
|
|
|
|
|
|
|
### Known problems ###
|
|
|
|
- Sometimes writes to a pseudo terminal will block causing the received
|
|
frame processing thread to hang. The first thing you will notice is that
|
|
received frames are not being printed. After a while this message will appear:
|
|
|
|
Received frame queue is out of control. Length=... Reader thread is probably
|
|
frozen. This can be caused by using a pseudo terminal (direwolf -p) where
|
|
another application is not reading the frames from the other side.
|
|
|
|
-----------
|
|
|
|
## Version 1.1 -- December 2014 ##
|
|
|
|
### New Features ###
|
|
|
|
- Logging of received packets and utility to convert log file
|
|
into GPX format.
|
|
|
|
- AGW network port formerly allowed only one connection at a
|
|
time. It can now accept 3 client applications at the same time.
|
|
(Same has not yet been done for network KISS port.)
|
|
|
|
- Frequency / offset / tone standard formats are now recognized.
|
|
Non-standard attempts, in the comment, are often detected and
|
|
a message suggests the correct format.
|
|
|
|
- Telemetry is now recognized. Messages are printed for
|
|
usage that does not adhere to the published standard.
|
|
|
|
- Tracker function transmits location from GPS position.
|
|
New configuration file options: TBEACON and SMARTBEACONING.
|
|
(For Linux only. Warning - has not been well tested.)
|
|
|
|
- Experimental packet regeneration feature for HF use.
|
|
Will be documented later if proves to be useful...
|
|
|
|
- Several enhancements for trying to fix incorrect CRC:
|
|
Additional types of attempts to fix a bad CRC.
|
|
Optimized code to reduce execution time.
|
|
Improved detection of duplicate packets from different fixup attempts.
|
|
Set limit on number of packets in fix up later queue.
|
|
|
|
- Beacon positions can be specified in either latitude / longitude
|
|
or UTM coordinates.
|
|
|
|
- It is still highly recommended, but no longer mandatory, that
|
|
beaconing be enabled for digipeating to work.
|
|
|
|
* Bugs fixed:
|
|
|
|
- For Windows version, maximum serial port was COM9.
|
|
It is now possible to use COM10 and higher.
|
|
|
|
- Fixed issue with KISS protocol decoder state that showed up
|
|
only with "binary" data in packets (e.g. RMS Express).
|
|
|
|
- An extra 00 byte was being appended to packets from AGW
|
|
network protocol 'K' messages.
|
|
|
|
- Invalid data from an AGW client application could cause an
|
|
application crash.
|
|
|
|
- OSS (audio interface for non-Linux versions of Unix) should
|
|
be better now.
|
|
|
|
### Known problems ###
|
|
|
|
- Sometimes kissattach fails to connect with "direwolf -p".
|
|
The User Guide and Raspberry Pi APRS document have a couple work-arounds.
|
|
|
|
-----------
|
|
|
|
## Version 1.0a -- May 2014 ##
|
|
|
|
### Bug fixed ###
|
|
|
|
- Beacons sent directly to IGate server had incorrect source address.
|
|
|
|
-----------
|
|
|
|
## Version 1.0 -- May 2014 ##
|
|
|
|
### New Features ###
|
|
|
|
- Received audio can be obtained with a UDP socket or stdin.
|
|
This can be used to take audio from software defined radios
|
|
such as rtl_fm or gqrx.
|
|
|
|
- 9600 baud data rate.
|
|
|
|
- New PBEACON and OBEACON configuration options. Previously
|
|
it was necessary to handcraft beacons.
|
|
|
|
- Less CPU power required for 300 baud. This is important
|
|
if you want to run a bunch of decoders at the same time
|
|
to tolerate off-frequency HF SSB signals.
|
|
|
|
- Improved support for UTF-8 character set.
|
|
|
|
- Improved troubleshooting display for APRStt macros.
|
|
|
|
- In earlier versions, the DTMF decoder was always active because it
|
|
took a negligible amount of CPU time. Unfortunately this sometimes
|
|
resulted in too many false positives from some other types of digital
|
|
transmissions heard on HF. Starting in version 1.0, the DTMF decoder
|
|
is enabled only when the APRStt gateway is configured.
|
|
|
|
|
|
-----------
|
|
|
|
## Version 0.9 --November 2013 ##
|
|
|
|
### New Features ###
|
|
|
|
- Selection of non-default audio device for Linux ALSA.
|
|
|
|
- Simplified audio device set up for Raspberry Pi.
|
|
|
|
- GPIO lines can be used for PTT on suitable Linux systems.
|
|
|
|
- Improved 1200 baud decoder.
|
|
|
|
- Multiple decoders per channel to tolerate HF SSB signals off frequency.
|
|
|
|
- Command line option "-t 0" to disable text colors.
|
|
|
|
- APRStt macros which allow short numeric only touch tone
|
|
sequences to be processed as much longer predefined sequences.
|
|
|
|
|
|
### Bugs Fixed ###
|
|
|
|
- Now works on 64 bit target.
|
|
|
|
### New Restriction for Windows version ###
|
|
|
|
- Minimum processor is now Pentium 3 or equivalent or later.
|
|
It's possible to run on something older but you will need
|
|
to rebuild it from source.
|
|
|
|
|
|
-----------
|
|
|
|
## Version 0.8 -- August 2013 ##
|
|
|
|
### New Features ###
|
|
|
|
- Internet Gateway (IGate) including IPv6 support.
|
|
|
|
- Compatibility with YAAC.
|
|
|
|
- Preemptive digipeating option.
|
|
|
|
- KISS TNC should now work with connected AX.25 protocols
|
|
(e.g. AX25 for Linux), not just APRS.
|
|
|
|
|
|
----------
|
|
|
|
## Version 0.7 -- March 2013 ##
|
|
|
|
### New Features: ###
|
|
|
|
- Added APRStt gateway capability. For details, see:
|
|
**APRStt-Implementation-Notes.pdf**
|
|
|
|
|
|
-----------
|
|
|
|
## Version 0.6 -- February 2013 ##
|
|
|
|
### New Features ###
|
|
|
|
- Improved performance of AFSK demodulator.
|
|
Now decodes 965 frames from Track 2 of WA8LMF's TNC Test CD.
|
|
|
|
- KISS protocol now available thru a TCP socket.
|
|
Default port is 8001.
|
|
Change it with KISSPORT option in configuration file.
|
|
|
|
- Ability to salvage frames with bad FCS.
|
|
See section mentioning "bad apple" in the user guide.
|
|
Default of fixing 1 bit works well.
|
|
Fixing more bits not recommended because there is a high
|
|
probability of occasional corrupted data getting thru.
|
|
|
|
- Added AGW "monitor" format messages.
|
|
Now compatible with APRS-TW for telemetry.
|
|
|
|
|
|
### Known Problem ###
|
|
|
|
- The Linux (but not Cygwin) version eventually hangs if nothing is
|
|
reading from the KISS pseudo terminal. Some operating system
|
|
queue fills up, the application write blocks, and decoding stops.
|
|
|
|
|
|
### Workaround ###
|
|
|
|
- If another application is not using the serial KISS interface,
|
|
run this in another window:
|
|
|
|
tail -f /tmp/kisstnc
|
|
|
|
-----------
|
|
|
|
## Version 0.5 -- March 2012 ##
|
|
|
|
- More error checking and messages for invalid APRS data.
|
|
|
|
-----------
|
|
|
|
## Version 0.4 -- September 2011 ##
|
|
|
|
- First general availability.
