Serial API

The Serial Applications Programming Interface (Serial API) allows a host to communicate with a Z-Wave chip. The host may be PC or a less powerful embedded host CPU, e.g., in a remote control or in a gateway device.

Versions

There are 2 available versions of SerialAPI:

• SerialAPI Controller
• SerialAPI End Device

The Serial API leverages the Z-Wave Protocol API. The Serial API introduces additional messages related to inter-host communications.

Interface on the DKNCZ20 board

The Serial API is accessible via UART through the USB connector. The configuration of the UART is: 115200-8-N-1

Manufacturer Info

Serial API supports a command named "Get Manufacturer Info" (0xEA).

This command contains a manufacturer specific chip info field that Trident IoT defines as the following:

• Manufacturer Specific Chip Info byte 1: Chip type
• Manufacturer Specific Chip Info byte 2: Chip revision

The chip type and revision aligns with the values in the "Get Init Data" command (0x02).
