Acquiring time from a timeserver is now spawned as a separate task running in the background. This avoids blocking HomeSpan while setting the time.
Default wait time has been extended from 10 seconds to 2 minutes, since there are no problems with blocking.
Allows user to define a custom style sheet to change the webLog output. Style sheet is based on pre-defined class:
bod1 = main body of web page, including header (in format of <h2>)
tabl1 = top table showing general status
tab2 = bottom table showing all weblog entries
Also added vTaskDelay(5) in pollTask to make sure competing tasks can operate (for example, if priority was set to greater than 2, touch sensor did not operate). Adding vTaskDelay(5) solved this problem.
Needed to support ESP-NOW on ESP-8266 chips, which seem to only work if connecting into softAP MAC Address once HomeSpan is connected to WiFi network (prior to connection ESP-8266 will properly connect to normal STA address as well as softAP address).
Provides for additional control over Status LED when a generic device has been used. If the color of the device is changed, the change will only take effect when the LED is next turned on. If the LED is blinking, the color changes upon the next blink. But if the LED is ON, there is no next blink and color will not change.
This method check the status of the LED, and if it is ON, is calls the on() function again, which will result in an update of the color. The method does nothing if the LED is OFF or BLINKING.
Applicable only for remote devices (i.e. not a Hub device). Last channel stored is used as initial channel upon reboot, provided that this channel is allowed by the channel mask (if not, the first allowed channel is selected instead).
* Changed ~SpanService to virtual function to ensure any user-defined destructor is also called
* Found/corrected bug in error message related to defining a Characteristic without any Service
* Added warning/error ID numbers to warning/error messages
* Other misc changes to clean up compiler warnings
Allows for bi-directional transmission between main HomeSpan device and one or more remote devices.
To Do: Create and test with Temperature Sensor Example
Added SpanPoint::setAsHub(), which is called after homeSpan.begin() to set device as Hub so SpanPoint knows not to change WiFi channel.
Also added check to make sure there are no SpanPoint objects instantiated before a call to homeSpan.begin() (if it is called at all).
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.
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.
