RE: Main loop bootup delay

The problem is you need to stop Zephyr configuring networking on boot up; if your controlling or deferring when networking is enabled.

Add the following to your conf and there will be no boot delay.

# Thread network is not going to connect on bootup, hence if we enable this
# we will end up waiting for a timeout set in CONFIG_NET_CONFIG_INIT_TIMEOUT
CONFIG_NET_CONFIG_AUTO_INIT=n

Hope that helps someone :)

Think i've found the problem after months of waiting 30 seconds on boot up haha.

When you enable openthread but have CONFIG_OPENTHREAD_MANUAL_START=y; you get a timeout condition on network config init. I guess because there is no network at that time.

Changing "CONFIG_NET_CONFIG_INIT_TIMEOUT=4" will give you a 4 second delay on boot up instead of the default 30.

I dont think this is a solution so to speak, as surely the network should not attempt to config if the app code is controlling when openthread is enabled.

I'll update on progress.
