Any resource for nordic BLE for iphone blind keyboard mode input.

[WFKwok]

Hello,

We see there is a HID BLE keyboard example in NCS and it works great.

So we are checking if we can using it or re-develop it for a BLE Braille Keyboard  to fit this Apple accessibility feature.

So is there any existing profile or resource available for this BLE Braille Keyboard development?

Any related information is welcome and appreciated.

Thanks.

Hello,

 Unfortunately, there is no ready-made profile or direct reference for BLE Braille keyboards. You can use the existing BLE HID keyboard sample as a foundation for developing a BLE Braille keyboard by customizing the HID report map according to Braille input requirements. You will need to refer the official HID usage tables and Apple’s accessibility documentation for further details on Braille keyboard requirements. (You will need to define a custom HID report map that matches the requirements for a Braille keyboard, referencing the HID usage tables(https://www.usb.org/hid) and [HID Service Specification] as starting points [Peripheral HIDS Keyboard References](https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/peripheral_hids_keyboard/README.html#references).)

Best Regards,

Swathy
