Have a look at my flight of May 28, 2024 in Weglide, the barogram looks weird with spikes to the downside, I have this since I changed over from a Redbox to a new LXNAV Powermouse flarm.
Files from the SD Card in the S80 Vario do not show this
Connection is via a Soartronic BT module to my Phone with LK8000. The BT in my phone is also connected with the radio.
I think it has to do with the Bt connection, but not sure. Anybody here who knows what is causing this and how to correct this situation?
During flight it does not seem to be any issue
Thanks!

Hi Marco,
This "sliced swiss cheese" igc trace looks a lot like a problem I had in Apr 2023 when using my LXNAV S100 to connect with SeeYou Navigator using the built in bluetooth on the S100. Naviter said it was a problem with the LXNAV BT firmware/hardware, but recommended I buy their LXNAV BT Dongle, which I did.
Got around to testing the LXNAV BT dongle with my S100 connecting to my Nokia 8 smartphone running SYN. It solved the "slice swiss cheese" dropouts. But, Paul Remde and LXNAV support tells me that between 2023 and Apr 2024 LXNAV fixed the problem in their S100 firmware. Now, I haven't tested it without my LXNAV BT dongle (using native S100 bluetooth) on SYN. LXNAV doesn't indicate this firmware update in any Change Logs.
Hope that gives you some help... |

BTW, Marco...
Will be taking delivery on a Samnsung A34 phone on your recommendation tomorrow. Waiting to see if I can install LK8000 on it and easily reach the needed folder for needed files without security problems. Also, hoping screen is bright enough and it doesn't overheat too badly.

in anycase, altitude written in igc file is the raw data received from active source, so 2 possibility
- spike come from the source
- you have connection issues and you have spike when LK8000 fallback from one source to another ... |

Issue is solved!
Updated the firmware of the LXNAV S80, to the April 2024 version (latest version). Which seems to have solved the issue. Thanks for the tip Walter Rogers!
Check my 04-06-2024 flight on WeGlide:

Marco, good news! BTW, I have a Samsung A34 5G and am struggling to copy in Waypoints.cup. Seems like LK8000 V7.4.5 is choosing a different directory than I can find from the Files app... or for some reason will not copy.
The directory I'm copying to is /Android/data/org.lk8000.beta
Some permissions problem or confusion...
Any help?

| run lk8000 first to get the permissions back, close and copy files using the 'files'app. |

Dear all,
The spikes issue is back again, and still trouble shooting. My configuration has slightly changed since last year..
I have installed a SteFly canopy flasher in my Mini Nimbus which is directly connected to the Power Mouse, with the Soartronic BT I had severe dropouts in the IGC file, also during flight I see many times the Flarm is disconnected, and then after a while it connects again, resulting in a very erroneous LK8000 IGC file.
I have tried the build in Bt module of the LxNav Powermouse last weekend, but still I see logfile drop outs, not as severe as with the soartronic and is more regular, like every 30 seconds it drops out for a moment. This also results in that I do not have two way communication with the Flarm anymore.
The SteFly Canopy Flasher has also a build in Bt, will try this the next flight.
What is also a possibility is that the Samsung A34 phone is the culprit, I will try my Pixel phone again, and see what happens. It has worked fine with my Pixel phone in the past.
Anyway, if anybody has a sugestion to solve this, please let me know. I will keep you guys updated with my experiments.
Flight with Soartronic Bt module as the data connection with the Samsung A34, LK8000 IGC file... Worked OK for quite some time, but at the end some severe dropouts:
https://www.weglide.org/flight/566771
Flight with severe drop outs, using the soartronic Bt module as data connection with the Samsung A34, LK8000 IGC file, note the long dropout between 11:30 and 11:45
https://www.weglide.org/flight/565642
Last (short) flight with Powermouse build in Bt as the data connection with the Samsung A34, LK8000 IGC file, short drop outs at regular intervals:

| What I have not tried yet is using the latest Beta version of LK8000, all links above are using the latest official stable version LK8000 7.4.5.. I see the beta is already at version 7.4.27.. maybe that helps... will try this as well the coming weeks.. Keep you guys posted about this. |

Thanks Bruno!
I have sent you an email with a link to a folder on my dropbox where the files can be downloaded, using the postfrontal email feature. I hope this works.
Kind regards, Marco |
