OT3m and Davis Vantage Vue on RF APRS Setup Help

Hello All,

I have been trying to get my Wx station working through the new OT3m. I have installed the Weatherlink 6540 for APRS unit inside the display, used the supplied Serial port adapter(blue 9 pin adapter to phone line looking plug), and verified it works with the windows Weatherlink software.

My question is how to get it to send data out the OT3m in a stable manner? I have the OT3m setup as "text" at the same baud rate the Davis display unit is set for. When I power up the system it runs ok sending out one report fine, but ALL other reports is just blank data (no wx data on the sent packet). I am thinking the streaming data from the wx station is out of sync with the OT3m?

Right now, the streaming config in the Davis unit is set for 5 sec timeout, 4800 baud, and transmission every 1 min. The OT3m is set to transmit every 5 mins. (thinking if the Davis unit sends out data more often a better chance for the OT3m to capture it. Same issue happens when they are both set for 5 mins Tx report time)

Example here of what I see.

otUSB xastir and the raspberry pi [1 Attachment]

[Attachment(s) from ramsatphones-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org included below]


I have setup my igate using the raspberry pi and xastir. Everything is working ok. When I look at the terminal in xastir I can see some errors when xastir tries to send KISS commands to the otUSB. Can anyone help me out with what else I need to configure on xastir so i do not get these errors in the terminal.

T3-9670 -- making contact to configure?

I’m a noob to Argent Data products and I’m lost here. i suspect the problem is that while I have two
physical T3-9670, the company’s wiki page and configuration tool are not updated yet for these units. 

What I want to know is, how would one give the TXFREQ RXFREQ and TXPOWER commands to a KISS device on a
Raspberry PI?  Or would you give them to the T3-9670 on using the MSWindows otwincfg.exe and then move them
to the Raspberry PI?  

I got the otwincfg.exe program to see the T3-9670 unit but I didn’t tell it to write to the unit because
there were too many things on the screen that didn’t make any sense, like the 1200 vs 300 baud selection
and on and on.

Can't Connect to OT3m with either Serial or USB

I just tried to setup my new OT3m and the unit is now non responsive. 
Below are the steps I took:

-Connected unit to PC via USB on a Windows 7 PC
-Windows installed the INF file and detected the tracker with no problem
-I opened the config software, entered my call sign an SSID and clicked 
-At the very beginning of the process the config program gave an error 
that it could not write block
-As soon as i received that error the device was no longer accessible 
via usb connection
-I then connected the unit to my PC with a DB9-DB9 null modem cable with 
hyperterm set to 4800 8N1 no flow control
-The unit displayed 1 character in hyperterm and thats it. (i hit enter 
and ctrl c quite a few times)
- I then tried to put the unit in safe mode bridging 1W and CT
-When i gave the unit power the red led did not flash and the unit did 
not appear to enter safe mode..

Any suggestions what I could try next?

Re: Intermittent problem between Nuvi 350 and T2-301

GTRANS and FMI cables are powered by the GPS USB port, but only when the 
GPS has external power.  It won't run from battery.

So what is the new product for Dayton this year?

Anything new that you are introducing?  And will it be a must buy item??/

I tried an inexpensive one and it didn't want to talk to my mac.  I also tried a non-inexpensive one (~US$50 or 60, IIRC), and it didn't work well either.  I gave up on serial/bluetooth.

On the other hand, that was well before Bluetooth 4.0, especially BLE (bluetooth low energy, which may have a different name now?). It seems to be specified well enough that even Apple hasn't found a way to make it incompatible with their IOS devices, so maybe it's time to revisit the subject.

I'd like to see an inexpensive serial <> Bluetooth device.   There are rumours that some have gotten the ones on Ebay to work but I haven't had the time/priority to track that down.    Then I can use software on my 10" Android tablet mounted in my vehicle such as APRSDroid and RepeaterBook and others.   RepeaterBook to let me click on a nearby repeater and have it update the settings on my Kenwood D710.  Or if I see a nearby repeater object on APRSDRoid, thus it is traveller friendly and popular in the area repeater that I can click on it and have it change the D710.

thanks!  hadn't seen that list.
> Ahh, the Garmin Montana

I had looked at the Montana.  It has several models and can pretty much do it all (although the screen seems just a bit small for auto navigation).  The thing I don't like (besides the price tag) is that the rs232 port is on the USB connector.

The MAP78 uses the old round 4 pin connector which seems much more suitable that a small USB.
> If there is a specific model you like

I'm kinda partial to the working, paid-for GPSMAP 60C I already own. :)

I'm beginning to wonder if a better solution is a beaglebone black with an LCD touchscreen cape running xastir.  The biggest thing missing is the routing and navigation.

Maybe we'll get the wireless protocols (ANT, etc) hacked into something suitable for APRS.

Ideally I'd like to use it with a T3, D7, xastir, my own software,

There are pretty rare.

Here's a list and down near the bottom in the section titled APRS Compatible GPS units.
Ahh, the Garmin Montana unit at http://info.aprs.net/index.php?title=VehicleGPS.  It has a battery and I recall one amateur stated he liked using it while hiking and while driving but I sure could be wrong.

If there is a specific model you like I'd do my best to somehow locate an amateur who is using such.  I know the Nuvi 350 and the Avmap Geosat series work.
