Handling 'DOWN' connection when sending message using send_message

[monkeyfdude]

I observe following code in test_suite:

apns:send_message(
  ?TEST_CONNECTION, ?DEVICE_TOKEN,
  Now ++ " - Test Alert", random:uniform(10), "chime"),

receive
{'DOWN', Ref, _, _, _} = DownMsg ->
throw(DownMsg);
DownMsg ->
throw(DownMsg)
after 1000 ->
ok
end,

If I understand this correctly (new to Erlang) its looking for "DOWN" message which will come as part of connection monitoring if the connection goes down - Ref = erlang:monitor(process, Pid),

• Does "after -> 1000" mean that apns worker will go down after 1 sec it detected a connection "DOWN"?
• Would this mean that message will be lost?
• Would apns_sup restart the worker process, reset the connection?
• What needs to be done for the message which was being sent when connection was detected 'DOWN'

Please guide me to understand this better.

If you send a message and the connection is down, maybe your token is not valid. What do you see in the logs?

I was just looking at the unit test and saw code I mentioned above. It got me thinking.

I was just trying to understand what should be the behavior when the connection does go down for some reason.
Or you don't expect the connection to go down at all???

What be the role of supervisor in this case?

I get this error on pans:connect

EDIT:

I could resolve the above issue by:

I am able to use apns4erl successfully...I may have other architecture questions...I will ask in separate ticket

Thank you all for your help and support.....can not be expressed in words!!!!!!!!!!!!!
