XR constantly losing app connection?



  • @MotoGPTy I sent in my XR to have the Bluetooth issue fixed under warranty. I didn’t pay anything. It is improved but not as good as my V1 or Plus.



  • I'm about to send mine back. Will be under warranty they said. I heard of quite a few people who had their board back and it works very good after.



  • @kanguru007 Here is the user manual for that Bluetooth module. It’s probably worth a look at. ILT254S: https://fccid.io/2AAXH-ILT254/User-Manual/User-manual-2126527

    It does have an external antenna pin on pin one of the PCB module. Not sure if it needs to be turned on to use it. I just sent my board in to “fix” it. I’ll see if it gets any better before trying this myself. I work with RF electronics so doing a little micro soldering is not a big deal for me, but I would doubt anybody can do this with out the right tools.



  • I just sent mine in yesterday. They say turn around is 2 weeks I hope so and hope they fix it. I figured with all the rain we are getting here in SoCal it is the perfect time to send in I will post the results when it is returned



  • Just got my Xr back from FM to fix the Bluetooth issue. Tested it for few minutes; looks like it works fine now.



  • I just got mine back. The signal strength seems to have a marginally improved. It held connection for about a minute into the ride then dropped. Still not usable.



  • @CLBR No, I'm riding bareback with no changes from the stock configuration.



  • I just got my board back from @future-motion and it seems like the BT issue is fixed. It connects super fast and I just went for a nice session and it stayed connected the whole ride with phone in my back pocket. The board came back with my miles still showing so I guess the main controller was not switched out. All I know is it works now like it is suppose to Thanks @future-motion for the quick turn around 11 days total from shipping to return Thanks, Thomas



  • @rfkilowatt @kanguru007 I'm in Argentina so sending to USA is no-way (customs cost as hi as U$S 1000 here).
    I'm electronic engineer and I have the right tools, maybe I will try to solder an external antenna (1/4 lambda). What do you think?



  • @tlamb2 THIS!
    It really works better! I was thinking in opening the board and soldering an external antenna, but this works! I've to test it more time, but great so far!

    You've to enter "Developer Mode" in Android.
    Go to Settings > System Info (the last on the list), then tap 7 times on the Build Number field (also the last field).
    Then go search in settings, and look for AVRCP, then switch to 1.6 as @tlamb2 says.

    That's it!



  • @gasppol Plus it also helps to clear your bluetooth settings in an android phone it seems to get rid of all the old Bluetooth connections making current connections better. In my work van now I am able to see text messages delivered via bluetooth to the vans audio unit which it use to do but suddenly stopped but after resetting my bluetooth that works now also. So it does something.



  • @gasppol Sounds great. Wish there was an iOS version of that fix.



  • For those who are in the market for used boards, what do we need to watch out for? HW version 4208 purchased between August 2018 and December 2018? Were all new boards affected, or only a subset? I can't really tell from skimming through all these posts.



  • @namespaced Pretty much all 4208 boards. 4206 (very first XRs produced) are not affected but did have the bricking issue.



  • @Rado do you know if new boards being shipped today still have this problem?



  • I’ve had a new XR for about a month and have recorded a dozen or more rides with no problems at all. I can walk 60’ away, line of sight, and still communicate with the board. iPhone 6. This issue was the most worrisome for me in before buying the board but doesn’t exist for me. Go figure???



  • @gasppol I’m an EE too. I’m going to try it with a 50Ohm low gain patch antenna and coax I bought from digikey. I’m going to mount it away from the aluminum cover plate. I’ll let you know if it improves things. That great a software change works with android.



  • @Kbnikto51 What hardware and firmware are you running? Maybe they fixed it? I’m running Hardware 4208, firmware 4134.

    To be clear, I can connect to the board when I’m dismounted. I once I get on the board, the phone and my Apple Watch lose connection. I can’t check my speed. I have to stop to check battery strengh. I also can’t track a ride.



  • Anyway, I’ve got news. I fixed it adding an external antenna. Works great now. It took it for a ride and I get realtime speed on my watch. Never worked before.

    I’m trying to find a way to post details on what it looks like. Maybe reddit or imgur.

    The antenna is a tiny little patch antenna that I stuck to the inner plastic part of the controller housing. You do have to unsolder and remount a 0402 cap on the Bluetooth module to remove the internal antenna and use an external one. Not easy, need a really good soldering iron like a Metcal with fine tips.

    Now I’m pretty sure its a signal strenght issue. Maybe it only affect some boards. Getting it reworked by onewheel customer service did not fix it. Maybe they replaced the module, but that was not enough.

    Here is the backside of the controller board. That’s the Bluetooth module, ILogic ILT254S. Pin 1 is for the external antenna. Pin 2 is ground. That cap needs to be rotated 90 degrees counter clockwise to switch the output to the external pin. This cap is an 0402, which means 0.04” long by 0.02” wide. Really fucking small! To move it (unsolder and resolder) you need really fine tips and a high quality soldering iron like a Metcal.
