An optional callback used to track the number of times the device reboots, where a reboot is defined as any restart where the uptime was less than a specified number of milliseconds (default=5000)
Low Memory Watermark is compared to DEFAULT_LOW_MEM_THRESHOLD (currently set at 80,000 bytes) after HAP initialization but before WIFI connection. If Low Memory Watermark is below DEFAULT_LOW_MEM_THRESHOLD, a WARNING is issued.
Note: memory is based on heap with MALLOC_CAP_DEFAULT capabilities
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
