Pretty complex change here: pending images/commands are now queued.
A command (like LED flasher) will not overwrite a pending image anymore. Also, sending multiple preloaded images is possible.
Also works (at least, as far as I could test) in combination with Multi AP and mirroring tags ('display a copy' content type).
It you want to test this: don't forget to upload the changed files in /www (the pending icon is now displaying the amount of queued messages). Timing improvements will follow later (only one message can be transmitted every checkin. If multiple messages are queued, at this moment, you have to wait until the next checkin which takes 40-60 sec).
This comes also with the advantage of better stability if you upload multiple images to the same tag in succession. Before queuing, if was possible to replace the image between sending the pending message and the image transfer to the tag, causing md5 mismatches and instability.
Solves #47
- changed ESPAsyncWebServer and AsyncTCP (both not properly maintained for more than 5 years) to more recent fork with bugfixes
- fixed concurrency issues in /imgupload. Hurts the upload performance a lot, but probably that's not a real issue. Parallel uploads are now possible (still within the max 5 TCP connection limit)
- added short date format definition in language.json
- changed english date format to mm/dd
- added lightgrey (4)/darkgrey (5)/pink (6) colors in jsontemplate (uses pattern dither)
- fixed ntp init timing
- got rid of gamma correction during dithering for quality reasons
- smaller UI improvements and textual edits
- tag grouping in the interface is now sticky across sessions
- tag auto update now shows before/after version number
- separated content types for 'not configured', 'static image', 'uploaded image' and 'home assistant' (which is all the same internally, but it confused the users to always see 'static image'
- changed channel reported by the AP to the ieee801.15.4 channel instead of the WiFi channel
- added geocoding to the 'location' fields (e.g. weather forecast). Now you can choose an ambiguous location from a dropdown.
- added 'firmware update rejected' wakeup reason
- Added Signika-SB.ttf and some small bitmap fonts
- Removed calibrib50/60/80/100/120/150 bitmap fonts, as they can be better rendered using truetype. Fallback is in place to auto translate to Signika-SB.ttf with the right size in case it is still used in a json template
- Renamed confusing tag type names to 'M2 + size' and 'M3 + size'. Because the universal firmware, there is no need to tell every subtile type change apart anymore.
- added `textbox` to json templates (https://github.com/jjwbruijn/OpenEPaperLink/wiki/Json-template#paragraph-text)
- redesign of count days/hours
- redesign of RSS feed
- designed Buienradar for more tag sizes
- on a scheduled or user initiated reboot, 'REBOOTING' is sent to the error channel of the websockets just before the connection is dropped
- phased out "hwtype": [] in content_cards.json (new location is in the tagtype json, which contains a list of valid content types)
In case of problems using this commit: keep in mind the heavy caching of the tagtypes in the browser. You might still unknowingly use the old contents.
Currently, the connection to WebSockets is hardcoded to the protocol "ws://".
If the server is put behind a proxy server (like Nginx) to support "https", the connection to websockets will fail (at least in Firefox) due to insecure protocol.
This change checks the current protocol and connects to "wss" if loaded via "https", which makes it work when loaded via proxy.
- in rare cases, an AP didn't connect to a WiFi network due to some tight timing
- bringing GPIO0 to LOW for more than 5 seconds now resets the wifi settings, in case you're stuck with e.g. a wrong static ip configuration
- optional previewtype and previewlut parameters for /imgupload call
- new 35.json for M3 6.0" (no template yet; coming up next)
- updated upload-demo.html
- prevent using html file for tag firmware update
- removed excessive logging
- fallback to .bak on tagDB load error
- scheduled reboot once at night around 4:00
