Hi all, sorry if this is a bit long winded
Got a strange one that TB don¡¯t seem to be able to help with. Resi project with
20 ipads as the only form of control (I know not ideal but out of my hands) the
problem occurs when there is no client activity for around 2-3 weeks, the ipads
randomly seem to ¡°lock up¡± [sic].
We have been trying various things for months now to identify
the problem and as we have similar systems out there working well it was a weird
one.
We have narrowed it down to the fact that the app does not ¡°lock
up¡± but actually only sends commands not receive them, so page flips and
feedback are not happening so the app appears to have locked up.
So, after 2-3 weeks of not using the app the app stops receiving
information from the processor, restart the app and all good!
I am sending a staggered serial string ¡°HELLO¡± to each ipad
every 3 hours to try and keep comms open but no joy
TB have had all the code and cannot emulate the problem,
although I doubt they left it for 2-3 weeks.
So I conclude that the issue is with the app, which when not
used for 2-3 weeks only allows 1-way communication on port 41794.
?
Any ideas, or has anyone seen similar?
?
Thanks for taking the time to read this
