- Updates all around tonight. Nothing major, but probably worth an
upgrade next time it's convenient.
For both the OT1+ and Tracker2, the processor should now shut down
(more) safely when the voltage is too low for normal operation. This
reduces the risk of code runaway trashing the flash memory.
Also for both, a bug has been fixed in the altitude-based profile
switching. A typo in a bitmask was causing errors in the comparison for
certain altitude ranges.
The OT1+ now has !DAO! support. Not that anything else supports it - I
think it might work with Xastir now. Compressed mode is still a better
way to get increased position resolution, but I'm trying to keep Bob
happy and stay up with the latest APRS spec proposals.
A separate firmware image is available for the Tracker2 for Proto C and
earlier boards that should return the LED operation and voltage
calculation to normal, since the main firmware image is built for the
OT2m v1.0 with extra LEDs and a different voltage divider.
otwincfg.exe has been updated so that the diagnostic screen calculations
are correct for the OT2m. They are NOT correct for the Proto C and
earlier boards, but if you've got one and don't like it, you can change
the resistors. Also, the labels and units in the profile switching
screen now change properly depending on your metric setting.
A bug was fixed in the OT1+ relating to handling of noise and framing
errors on the serial port, and hopefully this will solve some problems
with erroneous weather station operation.
Also relating to weather, the Tracker2's Ultimeter II support has been
tweaked slightly. It turns out that the UII puts out an extra carriage
return, and this was causing the T2 to spit out its console banner after
every line. It now takes an extra CR to get out of weather mode.
Also, the OT1 firmware that was listed as beta is now the official
All firmware updates have been posted to the source code repository.
- I'm a little confused about where to find the updated firmware and
configuration program are on the Internet - I've tried looking at
and I cannot see any files !
I have one of the beta T2 and I am also a little lost on the
discussion about resistor values. What and why do I have to change and
is it really necessary ?
- The freepository site only has the source code, which you only need if
you're going to modify and compile it yourself.
The compiled code is at http://n1vg.net/opentracker/downloads.php, and
I'll probably be creating a new page for it before long.
You can also just click on the 'Web' button in the config program and
select the firmware from the list.
The Proto C version differs from the production version in the resistors
used in the voltage divider that measures supply voltage. The larger
resistor is now 30k. And no, you don't really need to change.

How about the ability to print WX beacons to the
command line so that transmission can be igated? Any
chance to add it on the next iteration?

- Has anyone else updated their proto C with the new firmware? I seem to
have correct LED operations, but bogus voltage (18.3V?).
Seems like a resistor change is in my future, since this is a bit of a

- I updated my new OT2m with Tracker 2 firmware from the web and also my
Proto C versions by clicking on the "Proto C and earlier" firmware.
The OT2m voltage reads OK, but the Proto C's read 18.4v or so. I
thought one of the reasons for the two firmware versions was to negate
need to change resistors in the Proto C. Or did I get that wrong?
Also on the download page http://n1vg.net/opentracker/downloads.php,
there is only one ot2.s19. Looking at the code it is ver 54412, but
does not specify if it is the OT2m or "Proto C and earlier" version.
I have found the Proto Cs sometimes "lose their memory" and I need to
reload the firmware from laptop as one does't always have access to the
web when on the road. Can both versions be posted on the download page?
