Message sent twice after GPS fix timeout

Hi,

I have noticed a weird problem when sending a Sigfox message right after a GPS fix timeout: sometimes the message is sent twice with a few seconds interval.

Here's a log I managed to capture when the error occured:

--------------------------------------------------------------------

Here is a screenshot of the error on the Sigfox backend.

Does anyone have a clue on how to solve/debug this issue?
