Hashing of entire database is now done piecemeal within HapOut, preventing the need to load the entire database into a large buffer just to obtain a unique hash.
Modified updateDatabase() to use HapOut.getHash()
New Operator now uses PSRAM if available, else uses Internal RAM. Obviates the need for the ps_new() macro, though will keep definition since it may be useful for any class that does not already override malloc() to use PSRAM.
Reduces NVS consumption by from 3 to only 1 records when storing numerical values.
Also: Fixed memory problem in getCharacteristics by replacing dynamically-sized stack buffers with TempBuffer (must do this everywhere), which was causing stack probllem when combination number of Accessories and number of Characteristics got very large.
Added logic to sequentially transmit chunks of the HTML response String whenever it grows beyond 1024 bytes. This ensures the number of WebLog entries does not create a very large HTML String that eats up all the free heap space. WebLog entries are now only limited by storage of the entries themselves. Tested successfully with 500 entries.
When using PSRAM, changing the number of Accessories no longer creates any change to heap usage on internal RAM. The entire Accessory will be stored in PSRAM.
Forces all heap requests to be drawn from PSRAM, unless the device does not contain PSRAM.
To do: Provide easy-to-use NEW() macro; add custom allocator to unordered sets; auto-shrink vectors after updateDatabase()
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.
Allows extension of initial table produced in WebLog, where f is a function that returns a String. The returned String is copied into the WebLog HTML just before the </table> tag is printed in the initial table.
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.
Changed Serial.printf() diagnostic messages to either ESP_LOGI() or ESP_LOGW() macros in Blinker, PWM (LedPin and ServoPin), Pixel, and RFControl class
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).
Similar to CUSTOM_CHAR_STRING() macro, but does not include a parameter to set the default value (since the user can type an invalid string). Instead, user setData after creating the Characteristic as needed.
* 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).
