Any way to do something like blinking a led until SigFox.endPacket is complete?

Hello!

As we all might have noticed already it takes a while until Sigfox.endPacket method returns something and until that program seems to get stucked (the only thing that seems to work simultaneously is the BUILTIN LED if SigFox.debug is invoked... is there any workaroud for this? I mean, it is a bit confusing having to wait for about a minute in order to receive confirmation that transmission was ok. You might think device is broken or something.

Any suggestions/ideas?

Thanks,
Estela
