Yes, a general shutdown signal scheme makes sense, but still also a
separate SD unmounting signal to be able to remove just the SD card
with a single command.<br class="">

Writing the code last night, it seemed that the shutting down of
wifi/simcom/etc was messy.
<div class=""><br class="">
</div>
<div class="">Perhaps we need to have new signals “ShuttingDown”
and “ShutDown”, then make the components responsible for this?
So, for example, wifi powers off, server v2 disconnects, logging
stops logging to SD, etc, on “ShuttingDown”. Then SD unmounts on
“ShutDown”.</div>

<div class="">A better solution?</div>

Attention: performing an AutoFlash just killed my SD
filesystem.<br class="">
<br class="">
Possibly just by chance and I was lucky all the
reboots before, but I think we really need to close
all SD files before reboot -- see issue #97.<br class="">
<br class="">
FYI: the SD could be restored by a simple fsck, no
data loss. My Linux system also could mount the SD
before the fsck. The module was stuck in the mount
attempt.<br class="">

<div class="">Module will wake up sometime between
2am and 3am, and if wifi is available it will
check the available server version (according to
OTA tag and server url). If the server has a
later version, the module will download and
flash that new version then reboot into it.</div>
