sleep(0) not working when Gateway is down

[Snyfir]

Hello,

Why my node never sleep when Gateway is down and i use sleep(0) ?
if i do sleep(20000) my node will sleep after 10 seconds but when i do sleep(0) my node will never sleep. But i was expected it sleep after 10 seconds also.

Is it a bug ?

@Snyfir what is the return value of the sleep call? What does the debug output say? Those pieces of information will help a lot when trying to understand what is happening and why.

What type of Arduino you are using would also be useful.
