Gecko OS Commands

This page lists the Gecko OS Command API with a full description of how to use each command.

There are several interfaces for issuing commands. See Serial Interface, Issuing Commands and Streaming Data . For command format, see Serial Interface, Command Protocol .

Gecko OS Variables , which are used to configure Gecko OS, are accessed using the get and set commands.

The Gecko OS Command API is friendly for humans too. Use the following tips and you'll be an expert Gecko OS terminal jockey in no time flat!

Tip Description
Tab complete Type part of a command or variable name then hit the tab key. The command completes or partially completes, just like a terminal in the linux or DOS world.
History Up to 5 commands of history are available. Press the up-arrow key to access recently entered commands.
Edit The left-arrow , home , end and backspace keys may be used to edit or navigate commands already present on the command line.

Shortcuts

A shortcut is assigned to each command. Common sense dictates the rules for shortcuts. Commands that are already short do not need a shortcut other than their name, shortcuts for longer commands sometimes take the first three letters of the command name, and other times take the first letter of the name plus several other letters contained in the name. Shortcuts are no longer than six characters and are easy to guess, the ultimate reference however is command help and the documentation on this page.

Documentation Format

Many of the Gecko OS responses shown in the examples on this page were captured with system.print_level = all, and system.cmd.header_enabled = true. These settings are provided to make it easy for a host microcontroller to parse responses by examining response headers . Information about machine parsing is available in Serial Interface, MCU Config .

Documentation for each command is provided in the format shown below.

command

Abbreviation

cmd

Description

A description of how to use the command with, together with notes about available options and arguments.

Syntax

Formal command syntax with a listing of all available options and arguments.

Example

One or more examples demonstrating how the command is used.

Commands by Group

Description of Commands

dfu_query

Abbreviation

dfuq

Description

Query the Device Management Server (DMS), and return either Up-to-date or bundle version string if newer release available. If a newer release is available, use dfu_update to update your device.

Result codes and messages are:

Note : Querying the DMS requires a memory-intensive TLS connection, and may fail if memory is low. See Networking and Security, Increasing Available Memory for TLS .

Note : If the dfu_query command fails with the message: 

{"result":"fail","message":"device not claimed"}

then you need to claim the device before running the df_query command. See Update and Recovery, the DMS Server .

Note : The dfu_update and dfu_query commands replace the ota command for versions previous to v2.2. The ota command is deprecated and will be removed in the next major version.

Syntax

> dfu_query

Example 

dfu_query

dfu_update

Abbreviation

dfuu

Description

Initiate a secure update . The secure OTA protocol uses industry standard TLS/HTTPS security with both client-side and server-side certificate verification.

For details of this process and associated requirements, see Update and Recovery, Secure OTA Update . This process requires you to claim the device using the dms_claim command.

As an additional measure of security, the server authenticates each device using the universally unique system.uuid embedded inside the hardware of each device.

Downloaded bundle files overwrite local files only if the bundle file has a later version. To ensure that bundle files overwrite local files regardless of version, force an update with the -f option.

Download a specific firmware bundle version with the -b option. Specifying a bundle forces an update. Bundle files overwrite local files regardless of version. See the note for the -b option in Syntax below.

To maintain a saved configuration through an OTA update, save the configuration as default_config.csv .

Note : OTA requires a memory-intensive TLS connection, and may fail if memory is low. See Networking and Security, Increasing Available Memory for TLS .

Note : If the ota command fails with the message: 

{"result":"fail","message":"device not claimed"}

then you need to claim the device before running the ota command. See Update and Recovery, the DMS Server .

Note : The dfu_update and dfu_query commands replace the ota command for versions previous to v2.2. The ota command is deprecated and will be removed in the next major version.

file_create

Abbreviation

fcr

Description

Create a new file <size> bytes in length. After the command is issued, the ensuing <size> number of bytes is written to the file system.

Files can be written in chunks smaller than the specified length, using the -o option.

Additional options include a version, file type and CRC, or checksum .

See File System, Writing Files .

Syntax

> file_create [-o] <filename> <size> [<version> [<type> [<crc>]]]

Option Description
-o Optional. Leave file open for writing.
Default: Off
If the -o option is not specified, then all the file data must come immediately after the command.
If the -o option is specified, the file can be written in chunks. A stream handle is returned after the command. The write command is used to write data to the file. The stream closes automatically after the specified <size> bytes of data is written. The file is not considered 'valid' until it automatically closes.
If the module is rebooted or the close command is issued before all data is written, the file data is lost. It is not possible to restart writing the file after the stream is manually closed.
See Networking and Security, Network Connections and Streams .
filename Name of file to be written.
size Length of file in bytes. After the command is issued, write the file content to the serial interface.
version Specify version number. Default 1.0.0
type The file type, in hex format 1 . See File System, File Types
Default: FE ( MISC_FIX_LEN )
crc optional, CRC16-CCITT checksum of the file data, in hex format 1 . See File System, Checksum

                },
                { ... }
              ]
}

Notes :

String Replacement

Gecko OS allows string replacement in the URL of the file for download, using a C-like or pythonesque syntax.

If the url contains %s , then the supplied filename is substituted for %s .

Example: hdo 192.168.1.110:50007?id=%s&action=download my_file.txt generates the URL: http://192.168.1.110:50007?id=my_file.txt&action=download and creates the file: my_file.txt in the module file system.

String replacement is also available in the manifest. For example: 

{
   "path" : "http://myserver.com?file=%s&user=name&pass=1234",
   "cert" : "mycert.pem",
   "files" : [
                {
                    "remote" : "my_file1.txt",
                },
                {
                    "remote" : "my_file2.txt",
                },
              ]
}

generates the following URLs for download: 

http://myserver.com?file=my_file1.txt&user=name&pass=1234
http://myserver.com?file=my_file2.txt&user=name&pass=1234

http_get

Abbreviation

hge

Description

Perform an HTTP(S) GET request and return a network stream handle if successful.

The protocol is assumed to be HTTP unless otherwise specified in the <url> parameter.

For a URL longer than 124 characters the command and url exceed the maximum command line length.

In this case use the --long_url option instead of including the URL as a command argument. Send the long URL, terminated by \r\n , immediately after the terminating \r\n of the command.

To allow custom headers, use the -o option.

Timeout is determined by tcp.client.connect_timeout .

See:

Syntax

> http_get [-i <wlan/softap>] [-g < GPIO#>] [-o] <url> [ca_cert_filename]

where:

Parameter Description
-i Network interface. Possible values are wlan or softap . Overrides default specified by network.default_interface
-g <GPIO#> specify a GPIO to indicate buffered data is waiting to be read. Set to -1 to disable
-o Open the HTTP request but do not send. This enables custom header(s) to be added to the request using the http_add_header command.
<url> URL to which request is sent. The URL prefix http:// is optional for standard HTTP transactions, however https:* must be added for secure HTTPS transactions.

Options must be provided in the order shown.

http_head

Abbreviation

hhe

Description

Perform an HTTP(S) HEAD request and return a network stream handle if successful.

The protocol is assumed to be HTTP unless otherwise specified in the <url> parameter.

To allow custom headers, use the -o option.

Timeout is determined by tcp.client.connect_timeout .

See:

Syntax

> http_head [-i <wlan/softap>] -o <url> [ca_cert_filename] where:

Parameter Description
-i Network interface. Possible values are wlan or softap . Overrides default specified by network.default_interface
-o Open the HTTP request but do not send. This enables custom header(s) to be added to the request using the http_add_header command.
<url> URL to which request is sent. The URL prefix http:// is optional for standard HTTP transactions, however https:* must be added for secure HTTPS transactions.
[ca_cert_filename] CA certificate file. Overrides default specified by network.ca_cert

Options must be provided in the order shown.

http_post

Abbreviation

hpo

Description

Perform an HTTP(S) POST request and return a network stream handle if successful.

The protocol is assumed to be HTTP unless otherwise specified in the <url> parameter.

To allow custom headers, use the -o option.

The HTTP Content-type must be provided.

Timeout is determined by tcp.client.connect_timeout .

See:

Syntax

> http_post [-i <wlan/softap>] [-g < GPIO#>] [-o] [-l <content-length>] <url> / --long_url<url> <content type> [ca_cert_filename] where:

Parameter Description
-i Network interface. Possible values are wlan or softap . Overrides default specified by network.default_interface
-o Open the HTTP request but do not send. This enables custom header(s) to be added to the request using the http_add_header command.
-l <content-length> This replaces the default HTTP header Transfer-Encoding : chunked with the header Content-Length: XXX where XXX is the specified content_length .
By default an HTTP request is sent with chunked encoding. If this option is specified then chunked encoding is not used. This may be necessary for HTTP servers that do not support chunked encoding. After issuing the command, the write command must be used to write <content-length> bytes of data.
Note : If the -l option is specified then the connection will be left open, thus the -o option is not needed.
<url> URL to which request is sent. The URL prefix http:// is optional for standard HTTP transactions, however https:* must be added for secure HTTPS transactions.
--long_url <url> allows an aribitrary length URL string, with a maximum length of 1023 characters. The URL string follows the http_post command on the next line
<content_type> The Content-type, (Internet media type, MIME type), of the content to be posted (e.g. application/json ).

ota

Abbreviation

ota

Description

Note : This command is deprecated and will be removed in future versions. Use dfu_update and dfu_query instead.

Initiate a secure over-the-air update . The secure OTA protocol uses industry standard TLS/HTTPS security with both client-side and server-side certificate verification.

For details of this process and associated requirements, see Update and Recovery, Secure OTA Update . This process requires you to claim the device using the dms_claim command.

As an additional measure of security, the server authenticates each device using the universally unique system.uuid embedded inside the hardware of each device.

Downloaded bundle files overwrite local files only if the bundle file has a later version. To ensure that bundle files overwrite local files regardless of version, force an update with the -f option.

Download a specific firmware bundle version with the -b option. Specifying a bundle forces an update. Bundle files overwrite local files regardless of version. See the note for the -b option in Syntax below.

To maintain a saved configuration through an OTA update, save the configuration as default_config.csv .

Note : OTA requires a memory-intensive TLS connection, and may fail if memory is low. See Networking and Security, Increasing Available Memory for TLS .

Note : If the ota command fails with the message: 

{"result":"fail","message":"device not claimed"}

then you need to claim the device before running the ota command. See Update and Recovery, the Silabs DMS Server .

udp_server

Abbreviation

udps

Description

Start and stop the UDP server .

When the UDP server is started the read and write sub-commands are available.

When the UDP server is started, it is assigned a stream handle, indicated in the Gecko OS response by Opened: <stream> .

This allows for the equivalent stream read and write commands.

The read command is functionally the same as udps read .

The write command is functionally the same as udps write without the <address> and <port> options. The write command writes to the single UDP server stream, and consequently writes to all clients connected to the UDP server.

See:

Syntax

start, stop

> udp_server <start/stop> [port] Start and stop the UDP server. Port may be optionally specified. If no port is specified the default is udp.server.port .

read

> udp_server read [-q] [<byte_count>] where :

write

> udp_server write <byte_count> [<address> <port>] where :
