Librae / neurite - History

support dns captive portal while config wifi

It means, we simplify wifi setup steps:
1. connect to AP neurite-xxxxxxxx
2. open any website in browser(will be redirected)
3. save wifi credentials

user setup depend on connection to cloud

This fixes the potential bugs in 3rd party modules,
such as in servo library, servo attach will touch timer isr,
which may then cause conflict and crash the system
while connecting wifi.

fix a crash while ota

we need to suspend all the possible isr to ensure ota process

use user loop instead of ticker, fix a crash

The crash occurs when long msg arrives but the buffer allocated
in user mqtt processing routine is smaller, then wild pointer.
