All, I have noticed on the LX Nav website that a new firmware revision V2.0 was released last week for the V7. Do we know what bug fix and/or feature addition was incorporated?

Not really sure, but it appears that the gps signal status indicator has vanished!

Are you sure the GPS source and the V7 are set at the same baudrate?

I did check. The feed from the powerflarm to the v7 and on to Oudie/SYM is working fine. The oudie is definitely using the gps stream from the PF. We were previously getting the gps symbol bad then good as the pf locked on. Now there is no gps symbol at all on the v7, but the gps data indicates fine on the oudie. Internal gps on the oudie is disabled as backup, so the gps is definitely coming from pf/v7.

Hmm, strange... I think the GPS symbol is very usefull and I can see no reason to skip that. (I'm also using Flarm as GPS source)
Did you allready give feedback to LXNAV? It's not unthinkable that this is a bug in V2.00

I understand some of your concerns, but my partner and I still think this is the best vario we have ever used - and our prior was a 302. Once the vario is set up and the settings saved, the only thing you should lose on power down are Mc Setting, bugs and ballast. These are not too hard to deal with. We power ours up 10 min prior to takeoff, configure, and then leave on for the duration.

Our current settings are

phase Cruise Climb
needle Relative Netto TE
big number Netto Average
small number altitude altitude
averager 20 sec
smart filter 2
other important settings?

TE 3 sec
Cruise/Climb on a switch on the stick

We would like to see the ability to change the filtering speed between cruise and climb. Cruise should be on a slower response. We also use a chopped tone in climb mode and a solid tone in cruise mode to help hear the difference between the two modes.

The vario is not perfect but seems to be getting steadily better. We started with 1.97, so no clue prior to that. We treat this as a smart vario and air data feed to SeeYou Mobile. It would be generally a waste to put nav data up on the limited display space. That is what SYM is for. However, it might be nice to add a third (NAV) display in the cruise/climb rotary. So now it would become cruise/climb/nav and the nav display could allow you to use bearing and distance to the nav point - something like that.
etc

Quick update from the LX Nav website. A new firmware V2.02 is now available:

V7 Firmware news
Version 2.02

Implementation for flarm dataport spec. ver.6 (undirected warnings A/C mode)
Implemented Flarm status indication
added polar for Silent 2 targa and JS1-21m

Version 2.01

Implemented support for V7 Bluetooth module (external module)
Implemented warning for C/A mode
Some compatibility issues with XCSoar
faster power off
fixed some minor bugs

Version 2.00

New smart vario filters
improved needle initialisation
Auto baudrate
fixed some minor bugs


It should be also noted that LXNAV has created several "Firmware loading" software that can be used on PDA's, PNA's, etc! No need to log the laptop at the field. A simple PNA should now do the trick. Well done!

I Flew all 2012 with a V7 and never got the settings to my liking so I'm looking at possible other problems. The Temperature Offset reverts to 28.7F regardless of how many times I change it. I haven't yet updated the s/w due to PC issues. Any thoughts on the Temp Offset?

Bruce,

Update to the current Firmware 2.02, The temp thing at was a bug in the first firmware.

If you can't update send it to me Priority Mail at Craggy Aero and I will update the firmware for you.

Thanks,

Thanks Richard, I hoped that it might be the firmware! Do you think a temperature offset of 28F would cause 'bad behavior'? 28 seems like a large number.

Bruce,

I think that you have a very early firmware one of the first. Changes were made almost immediately by LXNAV if bugs were found. I remember that bug on the first batch I got from LXNAV in Nov 2011. I set the first V7s up on a bench with a variety of GPS and Displays and went thru all the menus and tested. I believe the bug was in the unit conversion with the temperature.. I make a practice of updating the firmware on all that I sell.

The update procedure and files are published on the LXNAV. Make sure you follow the procedure especially the 115200 Baud rate. If you need help call and we can set a time when you are at the instrument and I will talk you thru the procedure.

If this is the official V7 thread, then this would be a good place to let it be known that I have an official V7 vario available for sale at just $1200.

It is complete in the original box with both an Oudie cable and an IPAQ type cable as well as all the standard cables and accessories that come with the unit. The unit was purchased from Cumulus Soaring in March of this year.. The provided speaker and several cables were never connected. The unit saw only a short period of in panel usage before the ClearNav vario came out and replaced it for best compatibility with my ClearNav unit. It is in perfect condition.

I suspect that this V7 unit may need a software update if you want to run the latest and greatest V7 software -- the latest software can be downloaded from the website and updated in the field. The latest manual can also be downloaded.

Please contact me offline.

Did you not value all the extra info the V7 can display compared to the Clearnav vario (eg speed director at the same time as vario, graphic whole thermal average, and much other stuff)? What advantages does the CN vario give you?
