Ah sorry, I just realized that the problem is solved in the cutting edge fimware.

Hi,
I'm just moving from my v1 to v2 but I'm missing the background light. Is it correct that it doesn't light up when the arm is twisted? Always pressing the button is pretty annoying in the dark. Btw: A good improvement would also to be to light up on touch when touch is permanently enabled.

I would not count it, but store it in a global variable and then check it.

Ah, a very basic question fitting here which I wanted to ask since two years: What happens to event listeners and set intervals on Bangle.js, when the app is changed to another one (and therefore quit)? I suppose all listeners and intervals are cleaned up. Is this right?

Yes, I did. Finally moving to Kubuntu 21.10 did it. Thank you for the help!

Otk, there seem to be two seperate problems. One with Kubuntu. The other problem is obviously the Bangle.
What I tried now: I charged my second Bangle and connected it without any problem to the IDE and App Loader. The first Bangle still does not want to communicate properly.

Thank you for the hint. I tried this but there was no change.

Yes and reinstalled BT. The Bangle can be accessed from my phone, but it looses erratically connection. It the one I discussed here already: http://forum.espruino.com/conversations/­368381/#comment16201131
I tried also firmware v2.09 an v2.10.
I'm at the moment not shure whether it's Bangle or PC which causes problems. The Chrom(ium) problems are strange.

Hi Gordon,
thank you. I previously made some experiments with Node.js/Noble/Bangle which did not work (stuck on discovery while WebBLE did work). But this had not affected WebBLE.
Today it is not working anymore. The strange thing was that I had to enable experimental "Use the new permissions backend for Web Bluetooth" in Chromium which is -as far as I remember new- before I even got offered WebBLE in the IDE.

I restarted, un/reinstalled BT and Bluez and it is working with other devices.
In Chrome I don't even get a yellow connection button though experimental features are enabled. In Brave the IDE does not offer WebBLE. I got no more idea now.

Hi,
I'm facing a strange problem with WebBLE with Chromium running on Kubuntu. The device is visible and can be selected but the IDE does fail to connect to the Bangle v1. The browser log states:
either:

" No Services matching UUID 6e400001-b5a3-f393-e0a9-e50e24dcca9e found in Device.".

or

The app loader logs "NetworkError: Connection failed for unknown reason.

Has anyone an idea on this?

Neat. My app will be ported to v2 tonight ...

You'd be surprised that even the computer you're using has an opaque, second "brain" that >nobody except the manufacturer has any idea of what it's doing (maybe even tracking you?) >https://en.wikipedia.org/wiki/Intel_Mana­gement_Engine

I know what IME is and this problems also applies to NICs. But how should the Bangle watch screen firmware communicate with the internet? Even BT firmware can't do it.

In my opinion you can't get more safe with a connected watch than with this. Of course a mechanical watch is the safest one :-)

I don't understand this discussion as no one would change the low level firmwares of subcomponents. Most people don't know that they exist.

Sounds great. This will enable many new apps.

When I said mentioned my purchase decision what attracts me to the project is it was >advertised as "open source" in the 1st article I read, then I was told it isn't fully open source. > I am trying to move as much of my electronic life to open source projects.

Then this one is for you. The software is fully open source.

There are also regulatory reasons for closed firmware, since in some countries you are not allowed to change the way the radio system works since it may cause interference with other wireless products and they will loose their general operating license.

You mean that the android app could act as BLE http proxy to do basically any REST
call to the internet via the app?

exact.

Just a suggestion for the app: It would be nice to be able to define freely a couple of (REST-) URI so that Bangle apps can call the Android app e.g. URI 1 call with a=1 and b=2 like "request({1,1,2})" on Bangle. This should be easy to implement and helps people who don't want to modify the app and would open up great possibilities for new apps.

It has been the latest stable one. The reset problem (not the original problem with update of the bootloader) might have been related to a custom start image.

Hi Robin,

thank you. I resetted it without loading any code
https://www.espruino.com/Bangle.js#reset­ting-without-loading-any-code
I see an error: "ncaught error expecting first argu" which is strange since no app should be launched.

I tried several times (>12) to "delete all apps" and "install default apps" in the store, but it lost always the connection and got stuck.

However today I managed to complete the process and now I have default apps reinstalled. What is the difference to yesterday? Hm, it's the next day :-) I really don't know since the process was the same as yesterday around midnight.

Thank you for your time.

Tx

When resetting without loading any code it ends with "->bluetooth" but is not connectable. Firmware is the latest one.

Unfortuneatly my Bangle 1 is stuck with "Updating Boot0..." after updating the bootloader.
I can access the watch via bluetooth, but the connection breaks after short time.
I tried uninstall all apps/install default apps, but this fails with "no answer".

Any idea what to do?

I'd like to back Bangle Js 2 but it says rewards are not guaranteed? For those who back
have you received your reward?

Last time I did and Gordon has several other successful campaigns. Yes, you are right, on Kickstarter nothing is guaranteed. You have to assess the risks for yourself. In my case Gordons projects are up to now the only ones I were backing. If you don't want to back it right now on Kickstarter you may later buy it as a product on espruino.com, but with likely a higher price tag.

Also, didn't mention this on the KickStarter but after a period of not moving the
accelerometer enters low power mode (1.25Hz), and that drops power usage to 0.15mA so
you're looking at around 2 months battery life (with the screen always on!).

We have to call you Gordon "The Wizard" Williams from now on ... :-)

I hope we will get the 80k. The app will make Bangle.js even more attractive.
