[BRLTTY] Questions about Orbit Slate series displays

[Aura Kelloniemi]

Hi,

I'm looking for a multi-line braille display which has minimal refresh time,
has many buttons (including braille keyboard) and can be touched during a
refresh without disturbing it?

I guess Orbit Slate 340 display might be my only candiate, but I have a few
questions about it:

1) I saw an Orbit Reader 20 briefly, and it makes quite a lot of noise during
a refresh. Do the Slate series displays make equivalent amount of noise during
an update?

2) Are the Slate series displays able to (more or less) immediately update all
braille cells, just like displays mostly in use by BRLTTY users (I guess)? Is
there any noticeable delay in refreshing the display?

3) How much is the distance between the braille lines?

4) How does cursor routing work in BRLTTY with Orbit Slate? If I understood
correctly, it only has one row of routing keys per display – not for each
braille line.

5) How is the battery life?

6) Does it support Bluetooth LE (low energy)? How reliable is the bluetooth
connection (including with multiple connections)?

7) Anything else worth knowing about the display before getting one?

Thanks in advance!
