Goal - eliminate sendEncrypted() completely by using hapOut in tlvRepond().
Next up: use function call instead of << operator so logic can be moved into TLV.h
This completes re-work of all JSON buffer memory management to use HAPOut.
Next up: Stress test with Max Accessories to see how many Accessories we can now handle.
This removes last of large-sized JSON buffers - everything has now been converted to using hapOut.
Next up: Must add prettyPrint to hapOut to support 'd' command
But declared Streamer inside HomeSpan.h instead of separate Streamer.h since it should only be used when HomeSpan.h is used.
Also, changed class structure so that it is "final" by removing virtual tags and making all protected variables private.
New class-level method SpanPoint::setEncryption(boolean encrypt). Default is to use encryption unless method is called with encrypt=false.
With encryption, 7 connections max; without encryption, 20 connections max.
Serial Monitor provides warnings if connections are exceeded.
Stylistic only. Cannot remove .get() when a TempBuffer is being re-cast. Also can't remove .get() when cast can't be determined, such as when used in Serial.printf() [potential to do: explore if this can be addressed, though this is stylistic only and has no impact on code]
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.
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
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)
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.
* 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.
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).
