Spinel CLI Reference

The Spinel CLI exposes the OpenThread configuration and management APIs running on an NCP build via a command line interface. Spinel CLI is primarily targeted for driving the automated continuous integration tests, and is suitable for manual experimentation with controlling OpenThread NCP instances. For a production grade host driver, see [wpantund]: https://github.com/openthread/wpantund.

Use the CLI to play with NCP builds of OpenThread on a Linux or Mac OS platform, including starting a basic tunnel interface to allow IPv6 applications to run on the HOST and use the Thread network.

The power of this tool is three fold:

  1. As a path to add testing of the NCP in simulation to continuous integration
  2. As a path to automated testing of testbeds running NCP firmware on hardware
  3. As a simple debugging tool for NCP builds of OpenThread

Usage

NAME

spinel-cli.py - shell tool for controlling OpenThread NCP instances

SYNOPSIS

spinel-cli.py [-hupsnqv]

DESCRIPTION

    -h, --help
    	Show this help message and exit

    -u <UART>, --uart=<UART>
       	Open a serial connection to the OpenThread NCP device
	where <UART> is a device path such as "/dev/ttyUSB0".

    -b <BAUDRATE>, --baudrate=<BAUDRATE>
        Specify a serial connection baudrate. By default set to 115200.

    --rtscts
        Enable the serial connection hardware flow control. By default disabled.

    -p <PIPE>, --pipe=<PIPE>
        Open a piped process connection to the OpenThread NCP device
        where <PIPE> is the command to start an emulator, such as
        "ot-ncp-ftd".  Spinel-cli will communicate with the child process
        via stdin/stdout.

    -s <SOCKET>, --socket=<SOCKET>
        Open a socket connection to the OpenThread NCP device
        where <SOCKET> is the port to open.
	This is useful for SPI configurations when used in conjunction
	with a spinel spi-driver daemon.
	Note: <SOCKET> will eventually map to hostname:port tuple.

    -n NODEID, --nodeid=NODEID
        The unique nodeid for the HOST and NCP instance.

    -q, --quiet
        Minimize debug and log output.

    -v, --verbose
        Maximize debug and log output.

    -d <DEBUG_LEVEL>, --debug=<DEBUG_LEVEL>
        Specify the debug level.

    --vendor-path
        Provide a custom location of the vendor package. If not specified, the
        default location will be used (the vendor package shipped with the
        pyspinel installation).
        Note: The vendor package location can also be specified with
        SPINEL_VENDOR_PATH environment variable.

Quick start

The spinel-cli tool provides an intuitive command line interface, including all the standard OpenThread CLI commands, plus full history accessible by pressing the up/down keys, or searchable via ^R. There are a few commands that spinel-cli provides as well that aren't part of the standard set documented in the command reference section.

First, clone and build a simulated OpenThread NCP, as described in How to build OpenThread on openthread.io. After cloning bootstrapping, build the simulation example:

$ make -f <path-to-openthread>/examples/Makefile-simulation

Then run the Pyspinel CLI, using the path to your simulated build:

$ cd <path-to-pyspinel>
$ spinel-cli.py -p <path-to-openthread>/output/x86_64-unknown-linux-gnu/bin/ot-ncp-ftd -n 1
Opening pipe to ../../examples/apps/ncp/ot-ncp-ftd 1

Running the NCP tests

The OpenThread automated test suite can be run against any of the following node types by passing the NODE_TYPE environment variable:

NODE_TYPE Description
sim (default) Runs against ot-cli posix emulator
ncp-sim Runs against ot-ncp posix emulator with spinel-cli
soc Runs against CLI firmware on a device connected via /dev/ttyUSB

Manual run of NCP thread-cert test

# From top-level of openthread tree
$ NODE_TYPE=ncp-sim ./script/test clean build
$ NODE_TYPE=ncp-sim ./script/test cert tests/scripts/thread-cert/Cert_5_1_02_ChildAddressTimeout.py

Run entire NCP thread-cert suite

# From top-level of openthread tree
$ NODE_TYPE=ncp-sim ./script/test cert_suite tests/scripts/thread-cert/Cert_*

Command reference

OpenThread CLI commands

The primary intent of spinel-cli is to support the exact syntax and output of the OpenThread CLI command set in order to seamlessly reapply the thread-cert automated test suite against NCP targets.

See cli module for more information on these commands.

Diagnostics CLI commands

The Diagnostics module is enabled only when building OpenThread with the --enable-diag configure option.

See diag module for more information on these commands.

NCP CLI commands

These commands extend beyond the core OpenThread CLI, and are specific to the spinel-cli tool for the purposes of debugging, access to NCP-specific Spinel parameters, and support of advanced configurations.

Vendor package

Extension of the Spinel CLI with custom properties and commands. This plugin-like extension adds vendor-specific commands and properties to pyspinel in a way that does not impact the implementation of core pyspinel functionalities.

The vendor package contains the following modules:

MODULE DESCRIPTION
vendor Module that provides a specific vendor commands.
const Module with constants for vendor spinel extension.
codec Module that provides a vendor property handlers.

Each module comes with an example that shows how to add specific vendor codecs and constants.

By default, pyspinel will use the vendor package shipped with pyspinel installation. You can provide a custom vendor package location with --vendor-path option or SPINEL_VENDOR_PATH environment variable.

Vendor commands

The vendor package adds several vendor-specific pyspinel commands. Use the help command to list them all.
