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.
Added true/false parsing to all integer-based Characteristics. Previously true/false was only parsed for BOOL Characteristics. For integer-based on/off Characteristics, the Home App would send a 0 for off, and a 1 for on, consistent with HAP-R2. BUT...when using Home App AUTOMATIONS, the Home App would send true/false for integer-based Characteristics, which is inconsistent with HAP-R2. This meant automations worked with lights (that use the boolean ON Characteristic) but not with fans (that use the uint8 ACTIVE Characteristic).
With this "fix", true/false will be recognized all the time (except for float- and string-based Characteristics. Confirmed that fans now work with Home App Automations.
Ranges are now checked for all Characteristics at the end of the configuration, instead of at the end of each Accessory definition. This is much cleaner and the output is easier to read.
To do: Revisit use of REQ and OPT - what should constitute a fatal error and what should be a warning.
To do: Revisit Character definitions - attempt to normalize using the methods implemented for Custom Characteristics
No need to specify both FORMAT and TYPE. For example, specifying UINT16 automatically sets type to be uint16_t.
To do: Explore if this can be used for standard Characteristics - revisit standard Characteristics definitions and structure to see if it can be simplified.
Re-worked code to allow for NO Status LED Pin and NO Control Pin. If Control Pin is not set explicitly with homeSpan.setControlPin(), there will be no Control Pin. There is no longer a default since there are too many board variations with S2 and C3 chips now supported. Same for Status Pin - it will not be defined unless set explicitly with homeSpan.setStatusPin(), with the exception that if LED_BUILTIN is defined (i.e. there is a built-in LED), then the Status LED Pin will default to LED_BUILTIN if not explicitly defined. MUST UPDATE DOCUMENTATION - THIS CHANGES DEFAULT BEHAVIOR OF HOMESPAN AND MAY REQUIRE UPDATES TO EXISTING SKETCHES
Simplified enableAutoStartAP() so it no longer takes any arguments. It now simply enables the auto launch of the WiFi Access Point at start-up if WiFi Credentials are not found.
New method setApFunction() will now be used to set an alternative method for the WiFi Access Point. This will be called anytime 'A' is typed into the CLI, which also covers the auto-launch of the AP at start-up a well as starting it via the Control Button, since both of these functions call processCommand('A').
To enable save/restore for a Characteristic, set second parameter to TRUE when instantiating. Since first parameter was optional as well, this requires setting it as well.
Next up: Must add logic to setVal() to store new value as well.
Allows the user to add a command function to the Command Line Interface. All User Commands are defined with a '@' prefix.
To Do: Document this new feature.
Only throw a non-fatal warning instead of a fatal error if a Service is missing a required Characteristic. This allows for user flexibility in leaving out required Characteristics for Services that don't seem to need them (contrary to the HAP docs).
Also, changed PositionState Characteristic back to Required (instead of Optional) in WindowCovering Service (as specified by HAP). If PositionState is not included this will only throw an error instead of a warning as a result of the above change.
To Do: Update Example 13 to properly incorporate PositionState Characteristic.
Check is not applied to STRING Characteristics. Check is performed at end of each Accessory definition so will account for any changes to min/max as a result of calls to setRange(). If initial value is outside allowable range, a WARNING (not an ERROR) is thrown.
Also added new flag "staticRange" for all Characteristics that indicates whether the min/max range can be changed. An ERROR will be thrown if setRange is attempted for a Characteristic having staticRange=true.
Next TO DO: Complete entry of default min/max into all Characteristics (except BOOL and STRING) defined Span.h so that setRange() error checking works for all Characteristics.
Added Characteristics.h file that defines all static data for HAP Characteristics. Changed macros in Services.h to use this new HapChar structure.
Code is now more streamlined and ready for mix/max range-checking to be added.
Ensures robustness and is fully backwards compatible. User does NOT have to specify a template parameter, as the compiler determines this from the setVal() argument itself. Allows for any numeric type to be properly mapped to correct HAP format for the Characteristic.
This change is also needed to prepare for the refactoring of SpanRange, the addition of UVals to store HAP min/max, and new error-checking of min/max limits within setVal.
Updated setVal() logic to ensure that every possible combination of parameter type and Characteristic type is handled properly, and without generating a compile-time error related to ambiguous parameters.
New SpanService method addLink(SpanService *svc), where svc is a pointer to the SpanService that is being specified as a Linked Service for the current Service.
addLink() returns a pointer to "this" so may be chained
homeSpan.enableOTA() is now homeSpan.enableOTA(boolean auth=true). Set auth=false to disable password authentication. Set to true, or leave blank, to enable password authentication.
homeSpan.begin() automatically resizes maxConnections to ensure it is at or below maxLimit, where maxLimit=CONFIG_LWIP_MAX_SOCKETS-2-otaEnabled.
maxConnections still defaults to 8 if unspecified, which means it is reduced to 7 if OTA is enabled. Users should set maxConnections to a lower number is they have implemented other socket-based services in their sketch
HomeSpan will call a user-defined function upon establishing WiFi connectivity.
Set function with homeSpan.setWifiCallback(f), where f must be of form void f().
