Grrrr. This piece of hardware needs to be controlled by an #Android app.
Looks like it is still targetting SDK 28.
Despite me granting it all the permissions, it is still throwing an error.I can't seem to find a more recent version of it on *any* app store.
For future scholars:

Version 2.1.2If you want to try it https://file.io/VmtESDG0aPFg

Woo! Finally here and working.
I've bought a couple of 4-colour eInk badges.
They can be flashed over NFC or BlueTooth.
Full review coming soon - but let me know if you have any questions.

@Edent yo that looks really cool, is it something like this? https://www.aliexpress.com/item/1005007864502249.html
-
@benjojo similar. That one has, I think, a built in NFC badge.
This is the one I've got https://www.mrbretail.com/hsn371-battery-powered-electronic-name-badge-product/
It has a battery in it, so it can work with Bluetooth rather than just NFC.

@Edent gosh that's a lot of flickering - maybe to prevent stuck pixels on transition?
I feel like it needs to look like the moving pictures in the newspapers from Harry Potter.

@sarajw Yeah, black and white eInk can move pretty quickly - but colour still takes a lot of work.
-
@Edent How much did they cost you?
-
@andydavies ~£16ea + £3 for the battery. I had a free shipping coupon for AliBababa.
-
Graphic Design Is My Passion etc - but there is only so much you can do with four colours
-
@Edent Which four colours do you get?
-
@billgoats all of them
Black, white, red, yellow. What more do you need?
-
MULTIPASS! For @summerbeth

Trying to work out how best to reverse engineer this eInk badge.
I have a Windows app which communicates with a USB dongle. Could I sniff the communications from VirtualBox to my Linux host?
I have an Android app. I can decompile it, but I'm not really sure what to look for. Can I wireshark the Bluetooth LE connection it makes?
Thoughts gang?
-
@Edent I’d start with BTLE packet sniffing if that’s something you can do. If it’s unencrypted, you’re off and running. If it is, then decompile the app and go look for the key. If you then get lucky and find commands in an easy to read format, great, but I avoid reading decompiled code at all costs.
-
@benetherington which sniffer for Android do you recommend?
-
@Edent No clue, sorry!
-
@benetherington Have you ever done any BLE packet sniffing?
