# Appendix (examples)

## Command examples.

Example containing more than 1 command for sent/received server packet uses alternate colors for each command (and optional command data) for ease of understanding.

### Command example 1

 This example shows sent and received server message. The sent message contains 2 commands for Vicki:

* Read software and hardware version (Command code `0x04`);
* Set motor position to 300 steps and display digits/target temperature to 29 Celsius degrees (Command code `0x31`).

 The next received server message will contain also 2 commands from Vicki:

* The response to command code `0x04`;
* The standard periodically sent keep-alive command with its data.

**Example command:** `0x0431012C1D`

**Example response:** `0x042321011D5A78FA2C01F080`

### Command example 2

 This example shows server packet which consists of 7 Vicki commands:

* Set keep-alive period (Command code `0x02`) to 11 minutes;
* Set temperature ranges (Command code `0x08`) to 15 and 26 Celsius degrees;
* Set device operational mode (Command code `0x0D`) to online automatic control;
* Set target temperature (Command code `0x0E`) to 24 Celsius degrees.
* Get keep-alive period (Command code `0x12)`;
* Get temperature ranges (Command code `0x15`);
* Get device operational mode (Command code `0x18`).

**Example command:** `0x020B080F1A0D010E18121518`

With the next keep-alive the server will receive and the requested data from Vicki:

**Example response:** `0x120B150F1A1801011863530000008000`
