Connection without timeout

[hijae]

I'm using the this primarily for GPS logging rather than shutter. I would like the camera to continue to wait for a connection even if it briefly sleeps or is powered off, so that I can reconnect at any time.

I see, using furble as a passive, always on GPS data source.

Adding such a mode will not be kind to battery life, but I assume that is known penalty.
This is certainly possible.

We would need to:

• add a setting to control disconnect behaviour
  • try once, twice, indefinite, etc
  • default to current behaviour
• update the disconnect handler to respect the setting
• add cancel to the (dis)connect handler
  • this one is a bit messy, but nice to have
  • right now there is no way to interrupt or cancel the connect

I'll need some time to think about how to implement the cancel properly.

@hijae It appears that properly implementing this reasonably simple request will exceed the capabilities of the underlying M5ez library.
We have been consistently hitting the limits of this ageing library.
I am now exploring alternative UI libraries that can also support #80.

For now, you could hack the UI disconnect handler.
There is a reconnected variable which you can just delete. This will send furble into infinite reconnection mode.
The only way to exit will be to either:

• connect to a camera then exit properly
• forceful power off by holding the power button

I recently worked out this is possible with M5ez, but required a fair amount of rework, see #133.
Moving to an earlier milestone, that doesn't require a new UI.

With this feature, you need to connect successfully once.
After that, the reconnection logic handles things.
