This enables SpanPoint to operate as a standalone library with no reliance on anything in HomeSpan.
To Do: migrate all HomePeer code into SpanPoint. This will yield a universal standalone HomePoint library that can be used for BOTH the receiver and the sender (which automatically means two-way communication is always possible)
Verified ESP-NOW is communicating correctly with HomeSpan. Verified encryption works. Next step - create linkages between incoming data and Services; create queue structure to transfer data.
Eliminated constructor that had no pin parameter. Pin parameter is now always required. Since PushButton was not part of HomeSpan API, these changes should not impact any users.
Only initialize MDNS, WebLog, and OTA when first connecting to WiFi. Do not re-initialize upon re-connections after a disconnect.
Also, add number of disconnects, and reset_reason() to WebLog
The only reason to have used getAccessory(aid) is to delete it, so the delete command is now invoked automatically. Function returns 0 on success (matching aid found) or -1 on fail (aid not found)
Method homeSpan.updateDatabase(boolean updateMDNS) recomputes database hash and compares with previous hash. If changed, config number is updated and saved in NVS along with new hash. If updateMDNS is true, a new "c#" MDNS record is also broadcast with the new config number. This triggers HomeKit to call for a database refresh. Method returns true if config number has changed, or false if it has not.
The "C" command computes a hash of the current database config and updates the config number if needed. If config number has changed, the MDNS "c#" record is updated and the new config number is rebroadcast. This triggers HomeKit to immediately request an update of the HAP database so that the changes can be shortly reflected in the Home App without the need to close any Client connections or reboot the device.
The config number logic has also been updated/fixed. Previously it would create a hash from the full HAP database, which includes the value of each characteristic. Thus, initial value changes of Characteristics, as a result of stored values in NVS, would cause an update to the config number upon reboot.
This is not problematic, but also not intended, as a change in value is not really a change in the database config. The new logic computes a hash of the database that EXCLUDES all Characteristic values.
Rather than call homeSpan.poll() in the main Arduino loop() function, you can instead call homeSpan.start() at the end of the set-up function. This keeps the main Arduino loop() function free for user-defined code that will not block, and does not get blocked by, homeSpan.poll().
If using a dual-core processor, polling now occurs on core 0, instead of the core 1 (where all other Arduino stuff normally runs).
HomeSpan will throw a fatal error and halt processing if both homeSpan.poll() and homeSpan.start() are used in the same sketch.
