Unfrrtunately, the support for a capability usually follows the availability of that capability, especially when one doesn't participate in beta releases. I just recently acquired a device running Android 15, and haven't yet looked into its API for Bluetooth HID. I'll check it out.

Please clarify, as that doesn't make sense. Which model of braille device are you using, and what are the two keys?

Also, are you using brltty or TalkBack's braille?

If you're actually using brltty itself then, yes, you do. The place to put customized files on Android is /sdcard/brltty/. Note that this doesn't require that you actually have an SD card as that directory always exists, even if you don't.
