Specify with homeSpan.setSketchVersion(char *).
Read back with homeSpan.getSketchVersion().
Also, MDNS now broadcasts three new fields:
hspn = HomeSpan Version
sketch = Sketch Version
ota = "yes" if OTA enabled, else "no"
These are all optional to HAP but useful if trying to keep track of version updates when using OTA and Serial Monitor is not available.
OTA pasword now stored in NVS. Use 'O' command to change from default. Note password is stored as MD5 hash, and is therefore unrecoverable. Changes to password DO NOT take effect until next reboot. Password CAN be changed even if OTA has not been enabled for sketch. Blank passwords are not allowed.
Stored password can only be erased with 'E' command.
A 16-byte SALT with a leading zero would be sent as only a 15-byte number. The chance of this occuring is 1 in 256, which is small but still significant. Solution is to specify required size of MPI output in loadTLV. This forces mbedtls_mpi_write_binary() to pad with leading zeros.
Also eliminated unused code (TLV pack_old).
Setup ID can now be stored in NVS and set dynamically with the 'Q' command. However, homeSpan.setQRID(char *id) will override if present, but will not change the default stored in the NVS. This default wil be used once again if homeSpan.setQRID() is removed from the sektch.
If the NVS is empty, the default is set to "HSPN" as in version 1.1.4.
Class used for the creation and storage of a pairing QR Code (just the text, not the actual graphic) from a HAP Setup Code, HAP Category, and HAP Setup ID. The resulting QR Code text is output to Serial Monitor whenever the SetUp Code is generated or changed. The user can type this text into any QR Generator to create a QR Code graphic for pairing the device to HomeKit (in lieu of creating a printed tag of the Setup Code formatted using the Scancardium font).
Though not needed for HomeSpan, this class implements all the settings and parameters (such as Version and Reserved) used to generate any Apple HomeKit QR Code.
This class is used internally by HomeSpan and is not intended for the end-user.
