Is there a way to auto-sync files to a phone?

[ruvilonix]

I'm tracking data using a custom app and saving to a csv file on a Bangle.js 2. Every so often I open the Web IDE and save the file to my computer, but I was hoping for a more robust solution. Is there any way to auto-sync an arbitrary file to my Android phone via bluetooth every night?

There's nothing built-in, but you have some options (assuming you're using Gadgetbridge):

• You might be able to send an Intent from the Bangle (https://www.espruino.com/Gadgetbridge#intents). If you use the Tasker app on Android there seems to be a 'Write File' option, so you could configure Tasker to do that when it gets the intent I think.
• If you have an HTTPS server (either on your phone or that you configured yourself) you could HTTP POST the file to it: https://github.com/espruino/BangleApps/blob/master/apps/android/README.md#functions-provided

Both of those are reliant on the file not being too large (as it'll need to be small enough to be converted to JSON in the Bangle's RAM) but otherwise they're pretty doable

Thanks! I'll see if I can get one of these working.

I'm trying to just get started trying to make this work. I must be missing something with just the first step of setting up Remote IDE to be able to debug more easily. I open the Remote IDE server in GadgetBridge while my phone is connected. I enter the code into the IDE on my laptop.

It says then you connect to Android. Does it mean through Web Bluetooth? With my devices connected by BL, the phone doesn't show up in the device selector dialog in the IDE. Does it mean Web Serial? There's a long list of ttyS ports. I tried a few that didn't do anything.

You reload the Web IDE page, click 'Connect' and then a new device should pop up in the connection box called Android (at the same level as Web Bluetooth)

Oh hey it works! It's not showing up with Ungoogled Chromium which I normally use for the IDE, but with regular Chrome there's an Android button.

I implemented file sync in Chrono Logger: App loader, Repo.

It uses https://codeberg.org/Freeyourgadget/Gadgetbridge/pulls/3563. But it would need something like described in this comment by José Rebelo to become more useful.

Thanks! I missed that!

It would actually be handy to have a bit more info in https://www.espruino.com/Gadgetbridge about it - the command is listed, but not exactly what it does (like where is the file created, how do you access it?)
