1) Used `const char *` instead of `char *` where appropriate, including the need to create a dummy blank string for us in certain places.
2) Set initialization of WiFiClient to 0 instead of NULL, since WiFiClient is not a pointer (probably don't need to set it to anything since WiFiClient overrides the boolean operator anyway).
3) Cleaned up some of the messaging and logic when WiFi tries to connect so that users know to wait a bit.
4) Only remaining warning messages are for casting SpanService to (void *), which I think i unavailable (and is not forbidden).
To Do: Go through examples and check for warnings (will likely need to convert `char *` to `const char *` in many places.
User can specifiy a REQUIRED minimum version on the HomeSpan Library for the sketch to compile. If the library version is older, the pre-processor will halt the compilation with a #error output
RFControl::phase() allows you to add either a HIGH or LOW entry (i.e. a single phase of a pulse. RFControl::add() continues to add a full HIGH/LOW pulse so these changes are fully backwards compatible.
Made Characteristic::PositionState **optional** for Service::WindowCovering. This appears to be a bug/exception in HAP-R2. Need to reflect this in on-line docs.
* if Accessory ID is NOT specified, the default is aid=1+aid of last Accessory, with aid of very first Accessory always set to 1.
* aid of first Accessory must ALWAYS be set to 1 - if user over-rides with another value, error will be thrown
* validation now includes checking for duplicate aids, as well as ensuring the first Accessory is always aid=1
If not specified, "aid" defaults to an index number representing the order in which the Accessories were created. Values are stored as uint32_t (which is more limited than HAP requirements of uint64_t, but makes the code easier).
TO DO: Must add validation to ensure duplicate aid values are not used.
button(int pin, boolean isLong) changed to button(int pin, int pressType), where pressType can be SpanButton::LONG, SpanButton::SINGLE, or SpanButton::DOUBLE. Updated Example 16 and confirmed everything works as expected.
To do: Review all prior examples and update SpanButton when needed. Also need to update Zephyr Vent Hood code!
Added ServiceLabelIndex Characteristic, which seems to be required as noted in HAP specifications. However, linking to a ServiceLabel Service does not appear to be required, so there is no need to build any Service-Linking logic into homeSpan - will wait for use-case to be identified.
To do: Add support for double-click to SpanButton, then include in Example 16.
Modified SpanCharacteristic::sprintfAttributes to streamline logic and add special handling for the ProgrammableSwitchEvent Characteristic as required by HAP: the value returned for the database or any read request must be set to null (i.e. "value":null). The only time the real value should be returned is when the device sends a EV/Notify message (when the button is pressed). Verified that the example works as expected!
TO DO: Add functionality to allow for Service Namespace and Index label so that you can have multiple programmable pushbuttons in one service - this requires logic for HAP LINKED SERVICE functionality.
To do: Create special-handling code for ProgrammableSwitchEvent Characteristic (according to HAP, it has read permission, but must always return a null). Consider adding special flag to PR+EV
Added validation to ensure all Accessories have a AccessoryInformation Service and all Accessories have a HAPProtocolInformation Service, unless the device is configured as a bridge, in which case only the first Accessory requires a HAPProtocolInformation Service.
Checks to ensure that: (A) Characteristic is allowable (i.e. either required or optional) for the defined Service, and (B) Characteristic has not already been instantiated for the defined Service.
Completed macro to use HAPCharType for define Span Characteristic structures. HAPCharType includes name, ID, and permissions. The macro adds value type (e.g. int, double) and default value. To do: Create Span Characteristics for all remaining HAPCharTypes defined in HAPConstants.h
Created HAPCharType and added vectors for required and optional characteristics to every service. Next up: add all HAP characteristic types to HAPCharType
This prevents re-visits to the landing-page that resets the statusLED every time. Also eliminates the need to keep track of when landing page is accessed and to perform any initial re-direction.
Ensures statusLED indicates a client is connected as soon as it received its first GET, even if the re-direction to /landing-page is yet to be accessed. This was needed to trigger LED_AP_CONNECTED when connecting with QR code.
The 'A' command now resets any existing WiFi functionality so that it can start an Access Point without needing to first reboot.
To Do: Add a method to cancel out of apConfigure() and reboot by pressing control button.
To Do: Create time-out for commandMode()
Changing code so that it is possible to run HomeSpan without configuring WiFi. HomeSpan can already run without being paired, but requires WiFi at start-up. No reason to force WiFi to be used if device has buttons to operate the appliance withouth the need for WiFi or a connection to HomeKit. Work in progress...
