Adds a second type of WiFi Callback that is called every time WiFi is established OR re-established after a disconnect. Passes the number of times WiFi has been connected as an argument.
Changed fixed-size array `struct Controller[MAX_CONTROLLERS]` to a dynamic linked-list of Controllers. Re-coded all related functions. MAX_CONTROLLERS no sets the size of any buffers but is only used to limit the ultimate size of the linked-list.
Saved about 1K of RAM since most of the time there are only 2 Controllers defined (as opposed to the 16 allowed).
* Added support for zero-length TLV
* Added SEPARATOR as a formal kTLVType (and updated listControllers() to use)
* Added `uint8_t *buf(tagType tag, uint8_t *src, int len);` to load buffer needing external memcpy (and updated listControllers() to use)
Optimized use of heap memory instead of stack memory for temporary variables, and makes code easier to read, provided all heap usage is free() at end of each function.
Also removed char *hostName as a member variable of homeSpan. It's never actually used since MDNS constructs its own copy of hostName as needed.
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.
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).
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.
