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.
Instead of creating a static configLog for display upon start-up, an info log will be generated based on real-time data whenever the 'i' CLI command is requested. This provides for more streamlined error-checking as well.
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.
Need to revisit Television sketch - the latest iOS seemed to have disabled the ability to dynamically set visibility of input sources. Checking/Un-Checking the visibility radio buttons either during pairing, or after pairing on the settings screen, seems to be ignored by the Home App (the same input sources are shown in the selector regardless of any changes made). However, dynamically changing the name of an input source seems to work fine.
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".
This time using customized interrupts to fill RMT memory on-the-fly.
* Added getChannel() to RFControl
* Add 3rd, optional, boolean argument to RFControl(int pin, bool refTick, bool defaultDrive) to that RMT can be initialized but without the default driver (allows for use of custom interrupt code instead)
Pixels now lets you reserve memory for pixels so that the call to start the RF transmission can be done for multiple pixels at once. However, gain is not as much as expected. May need to revisit if driving a large matrix of pixels is needed.
Reflects increase in max number of LWIP sockets from 10 (Arduino-ESP32 v2.0.0) to 16 (Arduino-ESP32 v2.0.1). Since HomeSpan needs at least 2 (one for Server and 1 free for new connections), this leaves 14 connections for controllers. A big improvement over only having 8!
Constructor now allows you to specify high/low timings for 1-bit and 0-bit, as well as timing for reset delay. Default parameters are included if none are specified.
Also add getPin() to RFControl (which is used by SK68XX Class) as well as boolean operator overrides for both RFControl and PwmPin/ServoPin so that instances can be checked for validity.
Optional method to automatically turn off Status LED after a *duration* seconds. LED will resume normal operation any time it is re-triggered with a new pattern. This also resets the elapsed time used to check for autoOff.
