ESP8266 SDK2.0 fixes (at least, I can't reproduce it) an infamous bug
with crash during scan. 36K seams to be a safe value based on a download
test (test_dl.py), over 1GB was downloaded. More testing is needed, but
let's have other people participate by committing it now.
There is no automatic reconnect after wlan.active(False);
wlan.active(True). This commit provide the possibility to run
wlan.connect() without parameter, to reconnect to the previously
connected AP.
resolve#2493
It's mandatory function which should be present in every port. Even if
it's not, in the stdlib intro we waarn users that a particular port can
lack anything of described in the docs.
Now the function properly uses ring arithmetic to return signed value
in range (inclusive):
[-MICROPY_PY_UTIME_TICKS_PERIOD/2, MICROPY_PY_UTIME_TICKS_PERIOD/2-1].
That means that function can properly process 2 time values away from
each other within MICROPY_PY_UTIME_TICKS_PERIOD/2 ticks, but away in
both directions. For example, if tick value 'a' predates tick value 'b',
ticks_diff(a, b) will return negative value, and positive value otherwise.
But at positive value of MICROPY_PY_UTIME_TICKS_PERIOD/2-1, the result
of the function will wrap around to negative -MICROPY_PY_UTIME_TICKS_PERIOD/2,
in other words, if a follows b in more than MICROPY_PY_UTIME_TICKS_PERIOD/2 - 1
ticks, the function will "consider" a to actually predate b.
