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.
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.
Allows for daisy-chaining of configuration parameters.
Also added initialization of upLinkData in motorTask to prevent time-outs if setMove() is never called (by initializing msDelay=10)
Updated logic of setPosition(), move(), and moveTo() to use waitForAck() so that an initial acknowledgment is received from the motorTask() before proceeding.
HomeSpan now includes both drivers as part of the "extras" functionality.
The StepperMotorControl Window Shade Example has been updated accordingly to use the built-in TB6612 driver.
Changed Serial.printf() diagnostic messages to either ESP_LOGI() or ESP_LOGW() macros in Blinker, PWM (LedPin and ServoPin), Pixel, and RFControl class
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.
This has no effect on the code but the names of the macros can be used as flags for an external script to autogenerate documentation in the form of a list of all services and characteristics supported by HomeSpan
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).
If invert=true, PWM output will be phase-inverted. This is useful when creating a pair of PWM pins that need to be out of phase by 180 degrees (e.g driving a piezo-electric buzzer via two PWM pins).
Provides for additional control over Status LED when a generic device has been used. If the color of the device is changed, the change will only take effect when the LED is next turned on. If the LED is blinking, the color changes upon the next blink. But if the LED is ON, there is no next blink and color will not change.
This method check the status of the LED, and if it is ON, is calls the on() function again, which will result in an update of the color. The method does nothing if the LED is OFF or BLINKING.
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.
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).
