Rather than auto-enable OTA if not already enabled in safemode, changed the logic to simply rollback to previous app if OTA was used to download a sketch that does not itself have OTA enabled, unless OTA was previously enabled without safemode.
To do: Delete all complicated SpanOTA logic that (unsuccessfully) tried to track OTA status and check SHA246 partition codes to determine if reboot was OTA or Serial. None of this is need, but some of the code may be useful for other things in the future.
Since much of the Arduino-ESP32 library is precompiled, you cannot use -DCONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE to define this during compile time (it gets defined but is not used by the precompiled libraries).
TO DO: create an NVS entry that flags whether last update was via OTA. If so, automatically enable OTA regardless of enableOTA setting. This would ensure that OTA cannot be disabled accidentally by uploading a non-enabledOTA sketch to remote device.
Also updated SpanWebLog::addLog() so that the log message is also output to the Serial Monitor if the HomeSpan Log Level is set to 1 or greater.
To do: DOCUMENT ALL THIS!
If LOG1() or LOG2() is only provided with a SINGLE argument, then Serial.print() is called. This allows you to continue using LOG1() and LOG2() to directly print any variable or object that is handled by Serial.print(), such as an int, double, or even an IPAddress.
If LOG1() or LOG2() is provided with multiple arguments, the first is considered the format and Serial.printf(format...) is called. This allows you to use printf-like functionality within LOG1() and LOG2().
Gets IP address (as char *) of last client to send a request. Useful as part of web log messages. Will return 0.0.0.0 if used outside of any code that is responding to a client request.
Added isEnabled to SpanWebLog to indicate whether Web Log has been enabled. This allows the use of homeSpan.webLog.addLog() without ever enabling (in which case the log entries are ignored).
Also included logic so that clockTime is set to "Unknown" is addLog() is called prior to WiFi being established.
Next up: replace addLog(const char *) with a variadic set of parameters with dynamic storage allocation.
Also, updated error checking so that the UUID for both custom Services and custom Characteristics are checked for syntax. A fatal error is thrown if an ill-formatted UUID is found, since this will definitely prevent pairing with the HomeApp.
The UUID for HAP Services and Characteristics are NOT error checked, since these are fixed in HomeSpan.
Also, the custom Characteristics are not validated against the optional list for a service. If the user adds a custom Characteristic to a HAP Service, it is assumed to be valid. Similarly, none of the Characteristics (HAP of Custom) in a Custom Service are validated at all.
For developer use only - facilitates testing the same code across an ESP32, ESP32-S2, and ESP32-C3 without re-wiring by using an Adafruit FeatherBoard as a common jig.
Use homeSpan.reserveSocketConnections(n) to reserve n sockets *not* to be used for HAP. Multiple calls can be used to cumulate a total number of reserved sockets. This makes is easy to add reserveSocketConnections(n) at multiple point in the code whenever a certain number of sockets need to be reserved for use with that portion of the code. For example enableOTA() calls reserveSocketConnections(1).
If both setMaxConnections(), and one or more reserveSocketConnections(), methods are called HomeSpan will use the more restrictive net value.
Callback function must be of type void()(boolean isPaired). Will be called when device is paired and when device is unpaired. Allows for user-defineable actions upon device pairing/unpairing.
Pixel() and Dot() classes are now complete. Tested DotStar RGB, NeoPixel RGB, and NeoPixel RGBW, all running at same time on a single ESP32.
Next up: Must update Pixel Example as well as Holiday Lights Project
To Do: Add documentation page for Pixel() and Dot()
Pixel.h now contains Pixel() and Dot() classes.
Dot() class uses more streamlined methods; must next update Pixel() to use similar methods, which will allow Pixel and Dot to be more "interchangeable".
