clearly SD card is either full or stuffed, and there is no list of past sessions to delete.
My SD card has also died, it's not logging sessions either, although it does say there's room left on the card.

Thanks W100, but I'm an ancient light weight and do things differently

bit of a win today. I checked the difference between the koncept and speed battens. As I expected the Koncepts have a longer solid batten at the top camber, so I copied the Koncept, makes a big difference.
But now I have an over rotating camber above the boom. Makes it look like the batten is broken at the tip, but it's not. More investigating tomorrow, and see if the same technique can fix the 5.2

Take the bottom cam out and throw it away. Ive only ever used 3 cams

Now that's an idea!

Today I replaced the top batten with one that has a 5mm longer front section, from a Koncept, maybe that will help as well, could test it this arvo.

HELP!
I'm having trouble finding the .sbp files from my latest sessions. I've been linking to the unit with my phone and when connected I only find the following files:
A .txt file and a .gpy file for the sessions (although there was no .gpy file for yesterday).
When I've done this up until now there was an .sbp file to upload to KA72.
I've checked my other unit and it has .sbp files. Unfortunately I went for a quick sail today and only put one one unit on the boom. The loss of the data from today is no great loss, and yesterday I had my other unit for data, but I want to sort out what's wrong before the next windy day
Thanks
Thanks

Weird, all those files show 0MB, have you tried downloading the GPY file to see what's in it?
If it has data in it that should be fine, it's all I use.

Have a look at the configuration button, you can select different formats to be on or off, so if you really need the data in .sbp you can turn that on

Just checked, back in 2020 I had a 24kt alpha, so there wasn't any problem rotating it then.

Hi guys I've had a 5.2 and a 5.7 for years, but recently I'm having heaps of trouble getting them to rotate.
I'm using the same mast with the same settings, I don't think it's cambers sticking on the mast, my koncepts use the same masts and still rotate fine.
The impression I get is that the the body of the battens are too stiff, holding the shape forward. But battens don't get stiffer with age surely?
I think I have some old Koncept battens in the shed to test this theory with, I'll give it a try tomorrow, but in the meantime if anybody has any thoughts, I'm all ears???

Aren't you afraid to go slower with a smaller battery?

yes but you can fit round tighter corners.

I'm jealous, I had to replace mine, it's looking much too new at the moment.

The hard thing these days is to find a decent armband, most are too big and the excess flops around on your arm.
The Paqua Midi used to be my go to band but they don't seem to be around anymore.

well used worktop!

Unfortunately our DIY boom units aren't so easy. 3D printed and potted. They may come apart with a heat gun, but everything is still incased with epoxy.

Last time it was talked about, my memory says, the conclusion was that they are too draggy to get up to cavitation speed on a windsurfer.
But that was a while ago, things may have changed, as they do!

Proper paint helps too. ie: not Bunnings or the Wattyl shop.

I don't know Mark, I've had very good results with 2 pack estapol, very thin, should soak into the wood OK

If your sup takes a sail, just go with that.
There may be a reason nobody windsurfs on your lake, you just might find out what that is.

I found the 24kb limit problem, there was a small solder blob across a couple of terminals, somewhere around 32, v3 and 34.

So now it's working great, thanks guys.

This old brain couldn't remember how to do the Arduino thing.
And you are right on the money Jan, I just update to 5.91. that's done the trick autodetected the M10@ 115.2kbd
I'll give it a run tomorrow and see how it performs.

Thanks Jan, that would make sense, I'll have a play tomorrow.
However I've found another problem with the older BE that works fine on one SD card, but on two others it only records 24kb then stops recording. The one that works doesn't want to mount on my linux machine. Is it a formatting problem do you think?
The cards that don't work on this esp work fine on others with the same SW version.

That was interesting, it's using version 5.76 and it's slightly different to version 5.87.
5.76, after GPS auto detect, has an exclamation mark after GPS and a question mark after ublox.
So is the BE220 a ublox M10???? if not I've bought the wrong thing!!!!!
EDIT.
Just checked, it's supposed to have the M10050 ublox M10 chip.
Is this too new for the firmware?

Just tried an older M10, auto detect found it OK and worked well for about 10m then stopped recording, no idea why at the moment.

No luck, after boot it says auto detect GPS, then initializing GPS, then no frames in 10s.
I'm about to try the BE in another gps, don't ask me why it just seems like something I can do.

The settings for the type of GPS used is not in the config.txt anymore, but in EEPROM. With a fresh ESP32, the GPS type in EEPROM is set as "AUTODETECT at boot", so with the first boot out of Wifi reach, first the baudrate is detected, and then the type of GPS (M8, M9 or M10). If the gps is recognized, the EEPROM is written with the detected baudrate and type. The config.txt is also written, as info for the config in the webserver. If you connect a different gps now, next procedure is necessary :
In the config (webserver configuration), set the type as "AUTODETECT", and submit.
Boot again, and go outside. Now, a new autodetect should be started.
Let me know your findings !
Greetings, Jan.

Thanks Jan,
I think I've probably covered that procedure in my many attempts to get it working, so I don't hold out great hope, but I'll follow what you say exactly and get back here.

You checked rx and tx are not swapped? Check datasheet BE220 and BN220 used.

Thanks Paco, I find the instructions on TX, RX a bit ambiguous. I wasn't sure if the esp pin marked "GPS TX"
Meant the TX pin on the esp or the TX pin from the GPS, so I did swap them around, didn't work either way.
But as posted, it works with an older BN, so I have it correct now.
As you say the data sheet is worth checking, in the process of trying to solve this I discovered the min voltage for the BE is 3.6v not the 3.25 I was getting from the parallel outputs. so I've switched to the 5v rail instead, made no difference of course.

I have a problem with a BE220, It's not talking to the esp board.
At boot it says it's autodetecting the GPS, but after trying to configure it, comes back and says, "no gps frames for more than 10s"
Also for some strange reason , the config file isn't updating.
It says the changes have been saved OK but the config files hasn't changed from the old BN settings.

If I plug the old BN chip in it works OK.

I have a feeling if I can update the config file to the M10 settings it should work.

Am I doing something stupid here?????

Sorry mate that's too hard to read sideways, gives me a crick in the neck, so I've righted it.

I'd forgotten the GT31 only does max not 2s average

Unfortuanetly that link doesn't give foam density.
the stuff inside your board could be as low as 13kg/m3 and as high as 25kg/m3
Making some assumptions here, so could be way off.
looks like 20l weighs 1kg
m3 = 1000l
so this foam is around 50kg/m3
It will add some weight, but should do the job.

Mate of mine actually got multiply hooked. He crossed a long way behind a boat cruising down the channel ,without seeing all the rigs set up on the back of the boat. luckily the hooks were small and only got stuck in his wetsuit. But he drifted closer to the boat as he tried to unhook. the guy still had the motors running and he thought he was going to get diced. After much yelling the motors were cut.
Not a nice experience!!!!! I hate crossing that channel now.
