Thanks. I installed it from the Play Store but haven't gotten it to work with a Humanware display either Bluetooth or USB. It could use something like a status or test button, because there is no feedback as to why it doesn't work. Maybe a permissions thing, I don't know.

Hello,
No, I tested on Android 14, brltty works and is usable. You can install
it from google play, so documentation is correct in this.
https://play.google.com/store/apps/details?id=org.a11y.brltty.android&hl=en_US
I played with brlapi in Android and at least older releases are usable
with that simple tweak in build system which i mentioned.
My change causes, that libraries for all supported systems are generated
without version suffix, which is not good, we need it only for Android
libraries, i Did it only to test whether it will work with correctly
named libs.
With best
Peter
