Re my last boost, looks like HID support for Braille displays via bluetooth is coming in Android 15. This should let devices like the Brailliant BI 20X, 40X, The Mantis, and the Humanware NLS EReaders connect to devices running Android 15 via bluetooth. Fantastic news.
Clarification: These devices can be connected to Android devices via USB cables right now. The new support is for HID over bluetooth, enabling us to use our displays wirelessly.
