||
Version 1.1 -- December 2014
|
||
-----------
|
||
|
||
* Changes since beta test version.
|
||
|
||
It is still highly recommended, but no longer mandatory, that
|
||
beaconing be enabled for digipeating to work.
|
||
|
||
|
||
* Known problems.
|
||
|
||
Sometimes kissattach fails to connect with "direwolf -p".
|
||
The User Guide and Raspberry Pi APRS document have a couple work-arounds.
|
||
|
||
|
||
|
||
-----------
|
||
Version 1.1 -- Beta Test 1 -- November 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.
|
||
|
||
|
||
* 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.
|
||
|
||
|
||
-----------
|
||
Version 1.0a May 2014
|
||
-----------
|
||
|
||
* Bug fix:
|
||
|
||
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<4D>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.
|
||
|
||
|
||
* Bugs Fixed:
|
||
|
||
None.
|
||
|
||
|
||
|
||
* 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.
