2 -> Only network setup

|
Quick reference:
|
|
when use uiflow2.m5stack.com website, click RUN button to run workspace
|
|
code, boot_option won't change, if you click DOWNLOAD button to download
|
|
workspace code to device, boot_option will change to 2, it means after
|
|
download code done, device will auto reboot and won't show startup menu,
|
|
only do the network connect, but after network connect success, you can
|
|
still download or run workspace code. If you don't want do anything after
|
|
boot, you can delete this whole file. If you want show startup menu again,
|
|
you can hold BtnA(most device) and click reset button or repower device
|
|
until show the startup menu(for those devices with screens, and this is a
|
|
temporary method and may change in the future), after that the boot_option
|
|
will change to 1, so next time still will show the startup menu.
|
|
|
|
BTW, the network connection time has a default timeout (60s), you can modify
|
|
the following definition to change this default value.
