Hi,

How're you getting on with this?  I've been swamped in
work.  I got a cable made up last night to go to the
rig I have in the shack, I just need to update the
firmware now (Note to self, keyboard cables don't have
the ground wire and also PTT IN != PTT :) ).

Do I recall correctly that I can update the firmware
using xmodem?  the Windows Laptop that I had is no
more, so I only have zterm here on the MAC for sending
up the new firmware.

Regards
John

I've had a couple of reports of people (besides me) using it, but I don't
recall if any were on a Mac.  You need to use the .bin file, not the .s19
file.  I haven't been updating the .bin version because I haven't written a
translator program yet - preparing the .bin file is a multi-step process
that requires some manual editing.  Once I get a chance to automate it, I'll
make sure it's kept up to date.

The XMODEM support should be the standard, ancient version of the protocol -
128-byte blocks, not XMODEM-CRC or XMODEM-1k.  Just about any comm program
should be able to do that.

If the bootloader doesn't see the proper signature in the first block, it'll
just stop what it's doing.  You'll see 128 bytes transferred, and it'll
hang.

You should get a green-green-green-green-red sort of blink pattern.  Red
blinks are page erases, green blinks are row writes.  There are 128 bytes to
a row (and to an XMODEM block) and 512 bytes to a page.

Apologies for the previous blank email..

Just back from a club meeting,

The power switch is cool, very cool.. now I need
something to switch on with it :)

My voltage reading seems low, measuring R6 and R7.. R7
Seems low in value, though being in circuit, i'm not
sure how that would affect the readings.

Callsign of this one is EI7IG-14.

Cheers
John

It doesn't seem to operate remotely (neither does digi

I'm wondering if it should be EI7IG-7 (which won't

I couldnt' find the email with the command summary so
I looked in the files section, it probably should be
in there.. also I couldn't download "Tracker2.txt"

I just noticed that at some point my carefully laid-out, extra-wide traces
for the power FET got grabbed by the autorouter and rerouted as standard
traces.  The output trace is only 12 mils wide, when it was supposed to be
100 mils and routed on both sides of the board.

This means that for 'Proto B' boards you shouldn't run more than an amp or
so continuously on the switched power output.  If you need more power,
you'll have to solder directly to the leads of U3.  Previous 'Proto A'
boards should be fine.

I did confirm that the POWER command works OK remotely.

Scott

I've just about got some Rev B kits ready to go, but it turns out I ordered
the surface mount version of the XR2211.  Fortunately I'll need those
anyway, but I've got to place another order for the right parts.  I could
have sworn I had a small tube of those left, but it looks like they're all
gone.  Oh well.. should be ready on Monday.  <sigh>

The enclosure fabrication should be done next week.  It'll probably be
another week before they arrive.

I need to figure out a quick way to list unique items on my store, or maybe
I'll just use eBay.  Got a bunch of assorted assembled OT1m and OT2 test
boards and things to get cleared off the bench...

Scott

I've updated the .bin file on the website, so non-Windows downloads should
be up to date now.  You don't have the option of keeping your configuration
data - the XMODEM firmware update is all-or-nothing.  But you CAN make your
own .bin load now - hook up a T2, set it up how you want it, then
right-click on the title bar and select 'export firmware to .bin'.  Of
course, you still need a Windows box for that step...

The right name for those traces then is "fuse".  ;-)

Folks

My request(s) are somewhat bizarre but bear with me on this.   Now these
are very low priority items and fall into my wish list category.  From what
I've been reading the Tracker2 sounds very, very capable as it is right
now.  (Those on the NWAPRS mailing list will recognize these requests from
that mailing list.  )

I don't want to have everyone in the world knowing where my vehicle is all
the time.  Once I have APRS working it's just going to be sitting there
waiting to be used.

1) I'd like to see a standby mode where the Tracker2 is listening to APRS
packets.  Thus if my vehicle is stolen I can remotely send it an APRS
packet of some sort which it will then start beaconing.   This APRS packet
would, in effect, contain a password which the Open Tracker software would
recognize.  Needless to say once I used it I'd want to change the password
as this password would be stored in the various APRS data repositories such
as findu.com.

Now it's my understanding that the USA FCC doesn't permit remote control
operation on the 2m band.  But I'm in Canada so that restriction doesn't
apply.   Also I do realize that the vehicle would have to be in digipeater
range and the vehicle battery still working, etc, etc, for this to work.

2) I recently followed a possible drunk driver.  Unfortunately he was too
close to home for the cops to get their in time to stop him while he was in
the vehicle.  I was a bit confused as to what Avenue I was on for a number
of blocks.    So what would be nice is a switch on the dash where I can
tell the Tracker2 to start beaconing.   Now I'd setup a short URL on a
website for the 911 operator to see a map on where my vehicle is currently
located.  Such as whereis.ve6mvp.com.   So now the 911 operator can get my
position from the Internet rather than me having to figure out what street
or avenue I'm on when I've just turned.

(What is the delay between beaconing and being seen on the Internet at
places such as findu.com?)

Of course this requires that the 911 operator have Internet access.  My
understanding is that many do have Internet access and, if not, the
supervisor generally does.

No problem, just set INTERVAL to 0.  It'll answer ?APRS? queries (though I
could add an option to disable that in this case) and you can send an
INTERVAL command remotely to turn it on.  Or you could use the power control
option to just turn off the GPS receiver.  Personally, I'd prefer to use
that to kill the fuel pump!

I'm working on a couple of different authentication methods.  It's a
tradeoff between ease of use and security.

I think that's for 1-way R/C with no ID.  This should fall into the same
category as remote commands for a digipeater or mailbox.

You can do that with the configuration jumper or the 'transmit now' input.
A common setup is to put the text EMERGENCY in the second profile's comment
line, with a relatively fast beacon rate, so that you can flip a switch and
send emergency beacons that'll set off alarms on everyone's APRS displays.

Usually not more than a second or two.

I am going to add some kind of disabler device which requires me to hit a
switch of some sort which will then enable the fuel pump.   Thus a thief
who had hotwired the vehicle would not be able to start it.

Besides if the vehicle is indeed moving I'd sooner have the cops stop it
themselves and arrest the bad guys.  Rather than disabling it so they'd
abandon the vehicle.   Of course if they start running then it would be
nice to remotely disable the fuel pump.   I'm sure the cops would
appreciate that from a bystanders viewpoint.  As would I as there is likely
to be less damage to my vehicle.

<Rest of your response snipped>

Wow, very nice to see just how much flexibility you're putting into the
device.

Ah, now that's nice too.  You can tell the operator a few seconds after
making the turn, "Hit the refresh button now."

Thanks, Tony

The password would be easy enough to change at the police station
parking lot ? :)

No shortage of suggestions ;) but here comes another idea.

In addition to the existing remote operation;

A code word, recognized from, say, incoming messages, which
would just indirect into a pre-configured command. no acks no nothing.

The command(s) intended to be idempotent, would not cause harm if Eve the
eavesdropper replayed it (the fuelpump fuse would remain blown ;) Nor
would Eve know what it did, if it was not obvious from subsequent tracker2
behavior.

codeword 'power' could be published to a larger group, to switch a power
brick on/off for example, and the password stuff kept secret.

That could be done in the hypothetical scripting language.  I think it'd be
fine with the authentication techniques I'm working on.  Right now it's all
callsign-based.  Another one will be something you can calculate in your
head or keep on paper, and the third will be a true cryptographic MAC
that'll have to be generated by a computer.

Idempotence is actually a major concern in the command interface and
scripting language design.  It's very easy to get the same command multiple
times due to retries and network topology, and the flash memory has finite
write endurance.  That's an issue in scripting if you say 'execute this
configuration command when contact A is closed' - it'd be easy to erase and
rewrite the same page in flash very quickly and eventually destroy it.

My initial idea for a scripting language resembled a PLC's ladder logic,
rather than a procedural language.  I'm still leaning toward that sort of
setup, but it introduces some complexity in dealing with output events that
have to be edge-triggered.

I figured it'd be better to do it once the cops had the car in sight.  My
Accord has a 15 amp fuse on the fuel pump, so I think the simplest way to
set it up would be to power the tracker through that circuit (the high-side
switch can't switch a separate supply), making sure it's got adequately
heavy cabling, and just short the output leads of the switch.  When the
switch is turned on, it'll switch up to 20 amps before the current limiting
cuts in, but that's enough to blow the fuse.  You have to get out of the car
and open an access panel to replace it.

A simple relay might be better, though.  You could also kill the ECU, but
I'd be afraid of causing damage to the engine.  Killing the fuel supply
shouldn't do anything more dramatic than starving the engine and making the
car coast to a stop.

Before anyone tries to implement this, I should point out that my auto shop
grades were... well, not quite on par with my CS/EE grades, anyway.  =]

It'll be able to do a lot more if I ever get a chance to implement the
scripting language I've been thinking about.   That'll have to wait until
after the first production firmware release, though.

This 'code word' would not require authentication, it would be
a less-privileged thing. Instead of keys to the machine room,
you'd have a cord to pull, to reset the airconditioning.

You know the cure ;) Message identifiers.

> My initial idea for a scripting language resembled a PLC's ladder logic,

I guess a Forth-like language is out of the question. Easy to implement,
but, kind of crazy to usher people to code in RPN something, what
they could write by themselves and recompile, in the first place.

Responding to commands and initiating pre-programmed actions is a big part
of what I want the scripting language to be able to do.

Yeah, not a lot of room.. but you're not the first to suggest Forth.  I've
got a book on designing 'little languages' and their interpreters... I'm
hoping to get some insipration from that.  It needs to be line-editable
though, so you can make code changes remotely.

Scott

Hi Scott,

Any chance you could explain to me how to get this
working again.  I thought that I did have it working
before, but I'm stumped.  I cannot get it to work at
all.

(Lets pretend I'm stupid :) )

The power control commands?  It's POWER ON, POWER OFF, or POWER <0-255> for
pre-transmit power delay.

Remotely, it's CMD <whatever>, like CMD POWER ON.  Make sure the sending
callsign is in the AUTHLIST.  Use AUTHLIST +callsign to add a callsign to
the list.

Ok, I re-checked this.. It DOESN'T work with the mac
(NAK errors) and my USB serial adaptor, but it works
fine with hyperterm on a machine with a 'real' serial
port. I'll try minicom later.

Hmmm, In otwincfg I only get "Move", "Close" and

Interesting.  Does it show that it sent any bytes at all?  I had to use a
serial protocol analyzer to figure out what was going on when mine didn't
work initially.  Turned out my XMODEM documentation was wrong.

Did you get the latest version?  I just downloaded it to be sure and it
shows up for me.  Only when it's connected to a T2, though.

I'm working on getting the second serial port up and running, and I've hit
the first snag - I missed it before, but the second port doesn't have
programmable TX polarity, so if it's going to send data to any normal RS-232
device it's going to need an external inverter.

For the moment, it's hard-coded at 4800 baud and goes only to the NMEA
parser.  Without TX capability, it can't speak Garmin - no way to poll the
device and start PVT output.

There will also be some limitations imposed by the simplistic multi-tasking
model used by the tracker.  Depending on what you wanted both ports to be
doing, there might be timing limitations.  For example, processing a Garmin
position/velocity/time packet takes a relatively long time because of the
math required.  If the other port was running a console, you'd probably see
it pause very briefly every second or two when a new position was received.

A dedicated NMEA input seems like the simplest and most common dual-port
configuration.  I can see adding an option to disabled Garmin input when
it's in use - I use a Deluo GPS mounted in my car for normal tracking, but
I'll plug in my GPSmap 60cs when I want to see waypoints.  If the Deluo was
always used for determining the tracker's position, there'd be no need to
switch cables around.

What I need to know from everyone is what dual-port configurations are
important to you, and I'll try to support what I can.  Completely
symmetrical multi-port operation will probably have to wait for my next
project, though.

NMEA + KISS should be a common one.  Seems to work fine so far.

The second serial port can now be used as a 4800 baud NMEA input.  The new
Proto B boards have an RS-232 receiver/inverter on this input and it's wired
to CTS/RTS on the serial connector.

Also, this version improves handling of simultaneous NMEA parsing and packet
reception.  Things that were OK to do in interrupt context in the
OpenTracker cause problems with the timing-sensitive demodulator routines.
Profile-switching code needs to be reorganized next, and there will probably
be more tweaks after that.

It sends something, cause the OT2 doesn't work
afterwards.. the bootloader is all thats running I
guess

Cleared the cache on the machine and tried again...
now I see it..
