KONNEKTING Protocol Specification

The programming protocol uses group telegrams with the mostly unused group address 15/7/255. Those telegrams use DPT 60000.000, which is reserved for manufacturer specific custom extensions. The used Property Data Type is PDT_GENERIC_14, which is 14 bytes of raw data.

!!! It's required that no other device is using this address. Otherwise it may conflict with KONNEKTING Devices and programming your devices may fail !!!

Byte no#:	0	1	2	...	13
Used for:	Header, 2 bytes		Body, 12 Bytes
Description:	Protocolversion	Message-Type-ID	depends on Message-Type-ID
Range:	0x00..0xFF	0x00..0xFF

There are several message types for all kind of purposes. As we have one byte for the Message-Type-ID, we have up to 256 possible messages. That should be enough for our purposes. Same for version: Up to 256 versions should be enough for the near future.

Glossary

• HI high byte/"left most 8 bits" result in b[0] of 2-byte-array (big endian byte order, https://en.wikipedia.org/wiki/Endianness#Big-endian)
• LO low byte/"right most 8 bits" result in b[1] of 2-byte-array (big endian byte order, https://en.wikipedia.org/wiki/Endianness#Big-endian)
• GA group address, 1/2/3
• IA or individual address aka. PA or physical address, 1.2.3

Big endian example:

16 bits: 1111111100000000 result in

HI byte 11111111 --> 0xFF --> b[0]  
LO byte 00000000 --> 0x00 --> b[1]
Code: int16_t val = (b[0] << 8) + (b[1] << 0);
