LX Nav Varios, Bluetooth & XCSoar

I'm interested in connecting LX Nav varions (EOS or ERA) to XCSoar via bluetooth.

From the manuals, xcsoar config screens, and old posts here it looks like that *should* be possible.
Does anyone have experience doing it?
I've got XCSoar on a couple android phones and a nexxxus 7 tablet.
Simply providing vario data via bluetooth would be the primary need. Ability to feed flarm or other data would be a bonus.

Thanks!

Hi Sam,

I'm not an expert on XCSoar, but yes, the LX Navigation EOS and Era can send vario data over Bluetooth. So can the LXNAV S8 and S80 (with optional Bluetooth module) and the S10 and S100 (Bluetooth standard).

I have those all in stock.

Best Regards,

Hi Sam,

It is definitely possible and XCSoar provides a number of drivers to get everything talking nicely once BT is paired. The weakest link in the chain is the Android o/s (earlier versions are worse). If there is ever a problem or a delay in pairing, then Android remembers this as a "bad" connection and won't pair with the BT device. To fix it you have to clear the BT cache and pair from scratch again. I flew with a V7 (now S7), BT module and Galaxy S3, then used a Kobo Mini e-reader with HC05 BT module. In the end I removed the LX Nav BT module and went with a hard connection (to a Boox Onyx) via a IOIO box, though I know others who have never had any BT problems and swear by them.
Many problems in life come down to trying to get Box A talking to Box B. Sometimes the boxes are people

Which version of the Onyx Boox are you using?

I'm using the C67ML Carta+

Here's one for sale:

Official specs here, although their base model is now the Carta2:

Believe the EOS and ERA are from LX Navigation, not LX Nav. To me that confusion seems like the Judean People's Front and the People's Front Of Judea from "Life Of Brian".
It should work the same, the phone is the odd thing... With the LX Nav S100 (from down the road) I have connected a Samsung Note 4 running XC Soar using Bluetooth. Also a Nokia 8 running LK8000.
Pair the phone, then ignore the OS connection.
In XC Soar Config/devices, set up the BT as Device A at the same baud rate - I used 115,200.
Click "Monitor" and you'll see data.

....And I've connected an Android phone, a Dell Streak 5, and a Nexus 7
(individually and at different times) using a pair of K6-BTs.Â* I'm sure
there are less expensive devices to do this.Â* The key to getting vario
and Flarm data is to use two separate interfaces in the Android device.Â*
As said above, XCSoar provides the necessary drivers.Â* IIRC, the Flarm
uses 19.2K baud and the vario uses 4.8K. Good luck!

I'm the one JS was referring to when the LX NAV S100 paired and worked with my Nokia 8 Android phone and LK8000 software. It works beautifully... but. You have to spend some time at the desk testing all this and making sure the operator (me) understands how to pair on the Nokia 8 and get it working with my Flight Software LK8000. Once understood, it all works just fine.

Last summer at the Standard Nationals I used my Nokia 8 and LK8000 to fly for 100 full days with no problem. Just remember to test the connection and demonstrate it's working well before getting into the cockpit. For this contest I used a Nano and it's BT with my Nokia 8 and LK8000.

Power was from a "Juice" 5V battery in the side pocket of my D2a.

I'm convinced that connecting with BT is reliable enough these days. It's a lot simpler than a wired connection with IOIO-OTG boxes for Android. It even works with my Vertica V2.

Make that 10 days! I don't have the stamina to fly 100 days...
