1. tunr on fthe F40-new.
2. unlock phone (brltty started correctly)
3. Goto brltty->settings->manage devices->remove device, so I could
recreate it and log the connection.
4. When the device was removed, BRLTTY kept displaying info on the
display, something I didn't expect.
removing the currently selected device doesn't tell brltty to stop using it. If
it would then it'd mean instant loss of the screen for a braille user. Perhaps
it should raise an error and not allow the currently selected device to be
removed. let me know what you think.
With the current interface, you can only remove the current device. If no
device is selected, the remove button is disabled, so as far as I know, the
only way to remove a device from the list is by first selecting it as the
braille device to use. In most cases I don't expect people to have multiple
devices attached. The simplest solution seems to disable device removal when
brltty is active.
5. turn brltty off on is main screen.
6. recreate the device and try to make it the default (brltty stopped
messages started to appear)
Where did the messages start to appear? On the braille device?
No, messages appear on the phone screen and you need to press OK to
abandon them.
What I see in the logs you sent yesterday seems to show that the "brltty has
stopped" condition is occurring when brltty is supposed to be actually
stopping. This'd occur shortly after a reinstall (the old one is stopped and
the new one is started), as well as when explicitly stopping it from the
accessibility screen. Does this match what you're seeing? If so, what it
actually means is that brltty isn't stopping cleanly.
The messages occur when I try to select a braille device, or speech
method. The moment I press the device name, brltty halts and the message
appears. Also the setting isn't changed, so speech remains set to native
and the braille display stays set to 'no device',
7. Several useless attempts in which brltty always stopped.
Attempts doing what? Reinstalling brltty?
Attempts trying to set my braille device as the new display.
8. Completely reboot the phone. (brltty no longer stopped, however
there was no braille either)
It's hard to know why without a log.
9. Remove all devices from the bluetooth screen and pair the F40-new again.
This wouldn't be a brltty problem. I've found that the Android Bluetooth
pairing procedure can be a bit unintuitive for a blind user, although I forget
why, at the moment, since I haven't done it for a while. As I kind of recall,
though, it's timeout is a bit short (since a blind user has to either navigate
to the screen element containing the random PIN or slowly type on the awkward
on-screen keyboard), and then not realize that there's a Done button at the
bottom of the screen that needs to be clicked.
I am familiar with the way Android handles bluetooth, so normally I
don't have problems pairing things. My Android phone has been my main
phone for about a year now, so even the keyboard is quite useable to me.
The reason I decided to unpair all devices was I remembered someone
saying that brltty had trouble if the braille device wasn't the first
device found.
10. No luck, so reboot the phone again.
11. brltty started giving me (cannot connect to 'focus 40 bt'
messages with pairing requests from the display.
I don't understand. A pairing request would mean that the braille device isn't
paired yet. And, if it isn't paired yet, I don't see how it could be displaying
messages from the system.
These messages were spoken by talkback, not shown on the display. I agree
something went wrong during pairing.
12. Turn brltty off and entered the 0000 code again.
13. Turn brltty on and it instantly started doing what it should do...
At this point, is the driver set to autodetect or to Freedom Scientific?
Auto-detect. Don't know why this suddenly worked.
With kind regards,
Henk.
