Popular Post Unventor 6,366 Posted August 9, 2019 Popular Post Share Posted August 9, 2019 (edited) Issue: BT module might cause interference as reported by others, I don't have the wheel yet so I have not tested it. Fix: talk to your dealer there should be an update done by use stick. Note: My dealer will update my wheel before it is shipped.

Jon Stern 1,096 Posted August 9, 2019 Share Posted August 9, 2019 (edited) I just received an e-mail from @Jason McNeil with instructions on how to perform the BT interference fix (USB update). I'm going to try it soon. [Edit: apart from the fact I can't find a USB thumbdrive. Having to slowly reformat a 128GB microSD in a USB adapter as FAT32] Edited August 9, 2019 by Jon Stern Quote Link to post Share on other sites

Jon Stern 1,096 Posted August 10, 2019 Share Posted August 10, 2019 After failing to format the drive (it was too big for FAT32 - I assumed it would just get formated at the FAT32 limit), I went ahead and tried using the drive formatted as exFAT. It seemed to work. One thing to be aware of: the wheel now appears as a different BT device (same name), and has to be paired again. Quote Link to post Share on other sites

You can use the Disk Utility on a Mac to format to FAT32, and there are probably some ways to do it on android too if that's what you're wondering? Did a quick google on it and there seemed to be the capability. Quote Link to post Share on other sites

Windows sets a limit of 32GB for FAT32 because they want people to use NTFS instead (as it's more efficient for large partitions), but exFAT seems to work anyway.

I do you have an old surface pro 3 collecting dust but every time I use it I feel like I’m in the dark ages. LOL Quote Link to post Share on other sites
Popular Post Jon Stern 1,096 Posted August 10, 2019 Popular Post Share Posted August 10, 2019 FIXED! Having installed the Bluetooth fix, I just rode 12 miles without any random tilts! Half way, before turning around to come back home, I connected the BT to try some music, and the pedals tilted forward just slightly. I think it was when connecting (not sure why BT wasn't connected already), rather than when I started the music, but in any case it was very minor. Now I'm feeling really great about this wheel.

SamSuffit 242 Posted August 10, 2019 Share Posted August 10, 2019 I don’t understand: why the fix is done by USB key and not by firmware update? (It would be more practical) or is it for a quick fix, later also done by firmware update? Quote Link to post Share on other sites

I'm guessing the BT controller is independent from the main CPU and so has independent firmware that can't be updated wirelessly. Quote Link to post Share on other sites

(It would be more practical) or is it for a quick fix, later also done by firmware update? I don't know this for sure, but this is my guess from working as support from a major tech company. The BT module is a separate module inserted into the controller board. We have seen this on KS18L/XL, and I think I spotted this too on Ecodrits tear down too. If you were to access this while live and active on (the BT module) you might not be able update it at the same time. Another thing is by going by USB you risk less issues with broken connection or unable to connect in a scenario where BT fw is outdated. This happened to my iRobot floor washer, so they had to replace it. It happened too on my Inmotion V8 so I could only connect by Wheelog due to it having a manual BT mac address connection option. So here goes yet another fanboy, if you like argument, that they have thought about just happens to be by lucky a smart solution in worse case scenario to update BT module.

Having installed the Bluetooth fix, I just rode 12 miles without any random tilts! Update Sadly not fixed! This evening it was getting dark as I set off from work, so I decided to ride with some music (something I don't usually do) for enhanced noticeability. Halfway through my 4 mile ride I got a quite severe tiltback. Prior to this it seemed there was some slight pedal float going on. @Micheal Shen Edited August 14, 2019 by Jon Stern Quote Link to post Share on other sites
DjPanJan 622 Posted February 20, 2020 Share Posted February 20, 2020 I want to revive this topic and bring clarity to this thread for newbies. Is it still necessary to apply the patch to "younger" batches? Is there anyone who really helped? After changing the Bluetooth frequency, the connection is stable or dropped?. Many "older" ks16x are still in circulation. I don't mean batch 1th. Many vendors who used cargo ships and trains may still have a 2th batch due to the length of delivery from China. What we probably know. Motherboard 1.5 should solve this problem on the hardware level. Are there people who have never recorded a bluetooth patch and have "older" ks16x and have no problems with it? The firmware version should not be affected by this (1.05,1.06,1.07) on bluetooth. The Bluetooth module is standalone and has its firmware. What I have received information from vendors who replied to me does not need to apply this patch. Because in the forum this information is fragmented in multiple threads, it will be good to give clarity here. To sum up, I know (rumors and conjecture) There is no need to apply the Bluetooth patch to different batches than the first one. What you think? Quote Link to post Share on other sites

I don't know if it's the control board malfunctioning or whatever, but my wheel floats and dips around, and it's with the newest control board. I am trying the fix today to see if it actually fixes anything, or I'll be swapping the board yet again. Edited April 16, 2020 by George Iliev Quote Link to post Share on other sites

On flashdisk 1x mp3 + patch file. Plug in wait to flash complete and recalibrate 16X. Quote Link to post Share on other sites
Unventor 6,366 Posted April 16, 2020 Author Share Posted April 16, 2020 About floating pedals it is often a question of getting balancing/calibration done right. It might not always complete correctly despite it seem to be okey. You will know once you ride the KS16X. There seems to be an issue with having is biased going a little forward or backwards intentionally curing the calibrations. It just doesn't like it . Quote Link to post Share on other sites

There seems to be an issue with having is biased going a little forward or backwards intentionally curing the calibrations. It just doesn't like it . I tried the BT patch today, recalibrated as I always do - with a digital bubble level tool on top of the wheel, with degrees flashing between 0.00 to +-0.02. Today I rode the wheel for 10ish kilometers and didn't notice a single dip or floating. Possibly just a tad bit while accelerating, but it could be possible that's what they call "soft mode" (havent tried if it's there in hard mode). My dealer says if it's ok for another 24 hours (48 hrs in total) after that calibration, it could be the end of my issues. Apparently there's some problem with some of the KS control boards, where they won't keep a stable calibration for more than 16-24 hours. Will report again when I do some riding tomorrow or the day after. Quote Link to post Share on other sites
