While you are using the Orbit Writer for the first time, it starts with the default
channel, which is channel 1 and the default protocol which is SRP (Screen Reader
Profile).
By default, each Bluetooth channel is configured to connect over SRP protocol. If
you wish to connect over the Keyboard-HID protocol, you can switch.
By default, the USB channel is configured to connect over the Orbit-HID protocol.
If you wish to connect over Braille-HID protocol, you can switch.
Note
- After activating the Keyboard-HID protocol on any desired Bluetooth
channel turn off the Bluetooth of previously paired iOS/Mac devices on other
channels before enabling pairing on the desired channel.
