FIFO WAN issue if file of frame does exist #79

Open ArcticSnow opened 3 years ago

ArcticSnow commented 3 years ago

Here the mote tried sending a frame referenced in the FIFO list but the corresponding file does not exist (though the folder was existing). No idea why the file does not exist in the first place. Maybe we rebooted the mote at the time it was suppose to create the file, not sure...

In the following loop no data was sent via 4G because that very first frame was not found and the whole subsequent frames in the FIFO were not sent, and the 4G network switched off.

In conclusion we need to add an intelligent check if the file exists. If it doesn't then move to the next frame in the FIFO (or LIFO)
