Bluetooth Help

[Ankit Bindal]

Hi,
I tried to make an flow which connects Bluetooth device when disconnected after a sleep of 5 second.

But the problem is the flow end with an error after second loop.....

Please help.....

"with an error" is a bit vague, especially as you can read what error is produced. Not telling us what the "an error" is can only mean that you want us to guess. Ah, I got it - this is a kind of game, right?

[Bushmills]

My impression is that you experience a timing problem, possibly a race condition. I'd change the flow such that connecting both devices at virtually the same moment is made impossible. Example where this happens is here:

23.07.2016 08:29:33.593 [Flow1] Action 'Connect/Disconnect Bluetooth Device: Connect Headset I1100' Successfully connected to the bluetooth device
23.07.2016 08:29:33.594 [Flow1] End executing action 'Connect/Disconnect Bluetooth Device: Connect Headset I1100'
23.07.2016 08:29:33.594 [Flow1] Action 'Connect/Disconnect Bluetooth Device: Connect Headset QCY-Q8' Successfully connected to the bluetooth device

Catching the exception is not fixing the problem. You're merely hiding the symptoms.

[Martin]

In this case I would also recommend to not execute both connect actions in parallel since it's not well defined what Android effectively executed first in such a case.

Maybe you won't get the exception anymore when executing the actions sequentially (but this depends on Android version). If you still get the exception, you can switch to an exception-connection between the two actions and add a regular connection for the case when Android reported that it succeeded. Something like this should work:

I also used the empty action container since it helps to make the connections easier to read.
