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()
Significantly reduces memory usage - unordered_sets take up much more memory and using std::find from <algorithm> is as efficient as using find() method of an unordered_set.
To do: Remove all uses of unordered_set across HomeSpan wherever possible
Rather than use a large temporary buffer to store all encrypted frames to transmit all at once, each encrypted frame is transmitted as soon as created, which means the temporary buffer only needs to be large enough to store a single encrypted frame.
For a device with a large number of Accessories, this can save 15-20 KB of temporary storage, allowing for more Accessories.
Note this change does not reduce the size of the unencrypted message that is initially produced and can also be quite large. Potential for future project.
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.
