@robert-hh Thank you

@d-alvrzx I strongly support this request. I see, that restoring some of the data may cause trouble, if restore is executed multiple time w/o a save in between. Like the packet counters. But that is less cumbersome than loosing all data. See also my notes here to retrieve individual elements: https://forum.pycom.io/topic/5922/an-alternative-to-nvram_save-restore-using-the-sd-card/6?

@brunos ! With s.setblocking (True) before s.send(), it's OK !!
