the one contact which always has a voltage applied is corroded quite a bit, but this should not translate to inside the watch over time, hm?No, that should be fine, but it's worth covering up anyway in case it increases corrosion on the two outside pins that you need to charge it.
If pinching it makes it appear on Bluetooth then that would kind of clinch it - and might even bring it back to life.
ok, I think we are on the right track...I found the watch, charged it..and it was still not working...
but, I tried to remove the green stuff from the pin in question, just with some cloth (my t-shirt ;) )...and suddently there was a black hole...I removed a bit more on the sides then, and the rest of the pin has still some gold...but as you can see in the picture, somehow the pin has a small hole, which...not sure...
seems like the corrosion somehow found perhaps a weak spot or imperfection and got there through the remaining parts of the pin...I've not testet how deep this thing goes, but I think this could be some way for humidity to get into the watch...
My wifes bangle pin looks similar green, but apparently no hole until now...I hoe it stays this way :)

Hello Gordon,
sorry for the late reply, I only got the reply notification for fanoush and forgot about it later.For my watch:
- no showering with the watch
- the one contact which always has a voltage applied is corroded quite a bit, but this should not translate to inside the watch over time, hm?
- battery also seems not inflated
When I find it again (not sure where I put it, and its not where I'd expect it to be ;) ), I will try if a complete drain has helped, but I have little hope right now...
- no showering with the watch

Well, not sure if its the same problem, but I have (again) the problem that my bangle2 will not work anymore.
A few years ago the bluetooth died, and @Gordon replaced it...now it gradually got worse again over the last few weeks, and currently I can not get it to show up anywhere (web IDE, mobile, PC, DFU, nrf app, nowhere)
I've tried the new recover option, and according to the page it should then be visible...
Since the "bluetooth broken" idea was thrown in again, my question would be:
Why does the banglejs2 bluetooth sometimes just...seem to die?
My wife has still her first bangle2, and its still working...mine seems to be bluetooth-dead again...Any ideas what could be the reasons besides bad luck? Could there be any app/logging or such be the reason?
I tried the clean boot in the recovery, and it showed a CRC error...but otherwise it was working until now, besides the gradually bad working blueooth over the last few weeks.
Now I tried Power off and left it for some minutes...turned it back on, and it has wrong time (ok, to be expected ;) ), and since it will still not connect, I can leave it off my wrist :(Greetings, Uno

Hello Gordon,
thanks for the reply.
No, no improvement yet...more the other direction. I will try again the squeezing a bit later. But right now it did not connect or show up anywhere. When I wrote the post above there were some chances to get at least half a connection every now and then. Right now it was completely dead.But what you say with the squeezing matches with my obersavations back then. If there is a chance I can squeeze bluetooth on, this would explain why it worked so erratic.
Can you explain a bit more how/where I should sqeeze to get better chances?
As for the other question: It was one of a "2-watches", blue Kickstarter Bangles which got sent later to Germany because of the customs problem, and has also all 4 pins exposed (ok, mine right now with a bit partly removed nail polished on the center two :o) ).
So I would say a rather early bangle js 2.Greetings,

Hello,
I have now a similar problem...
right now i'm on vacation, so a bit time here and thereto play around and rule stuff out, but cornerpoints are:- Without noticable reason no bluetooth connection possible
booting into dfu/no code mode most of the tries does not help
dfu mode and updatefrom 2.14 to 2.15 finally worked using the web ide, but was not visible in NRF toolbox/NRF DFU thingysometimes a factory reset helped, and sometimes gadgetbridge was at some time able to get a more or less long connection (noticable because time got synced)
i got it so far working that I could use the apploader to upload my apps (LCARS, android/messages quitemode and some others)
it worked for a bit but is broken right now, not visible in any case/mode at the momentwill try tomorrow again with different phone which I used for succesful firmware upgrade
i'm away from home,so tomorrow I will disable any devices we have with us and have bluetooth, but if I understand right the only critical would be devices which were at some time paired to thewatch using BT oder gadget bridge...no "just have bluetooth enabled" devices...
right now my only explanation for this erratic behaviour is a hardware error, but I'm willing to try a more systematic approach if you guys have ideas others than go in to DFU/no software mode...
the watch of my wife currently is still working
another point:successrate was better after reboot of the phone used for flashing, but also no consistent results using reboots to get a connection *sigh *
so long greetings,
Uno/Georg - Without noticable reason no bluetooth connection possible
we put nail polish on it, right after the kickstarter back then...but seems like we should gently redo it...On my 2nd bangle I did try to protect it in the beginning, but since it would still go over time through the protection I gave up at some point...(never would have thought it ends up like this...I thought it gets a bit green but would not go a lot deeper ;) )
I'm not sure how well the casing/pins will response to attempts to clean up the old polish first with polish cleaner stuff...do you have experience regarding this plastic and such cleaners? It was a non-aceton-clear-polish I think, so the newer, 'healthier' stuff ;)
Otherwise I don't think simply a new layer of nail polish on the old partial cleaned polish will help a lot, hm?
