Hello All,
Actually finishing intgration of brlapi in our application and thinking
how to fix this:
I successfully connect to brltty and start to monitor
PARAM_DEVICE_ONLINE and some other parameters.
If there is a display communicating with brltty when i connect, i
successfully receive true status of online parameter, can call
connection.enterTtyMode(0); and start to work with the display.
But there is a problem if there is no display when i connect to service.
I receive change notification of online parameter immediately when some
display successfuly connects to brltty which is ok, (i actually play
with orbit 20 via bluetooth). But my app crashes when i try to call
connection.enterTtyMode(0); in this case.
I tried to check connection.isUnusable() (may be that connection must be
reset after display reconnection) but it returns false, so no reason to
reconnect.
What should be wrong?
I thought to reset connection if I receive online parameter change
notification later than say 1 second after successfull connection, but
it looks like a nasty solution. :) Is there something better i can do?
