Commands send from the Host to the Unit start with 0xAA.
|
|
slime@2

Warning: A complete Packet _must_ be smaller than 64 Bytes. This is a Firmware limit!
|
|
slime@2
|
14 |
Therefore, LENGTH_UPPER is always zero.
|
|
slime@2
|
15 |
LENGTH_LOWER ist the number of Data bytes, following the header. The Firmware will scrap the complete package, if length is not correct.
