Get the latest version of the Agent for all supported platforms:
arduino-create-agent is a fork of @johnlauer's serial-port-json-server (which we really want to thank for his kindness and great work)
The history has been rewritten to keep the repo small (thus removing all binaries committed in the past)
The agent supports multiple configuration files. When multiple configurations are found by the agent, the tray icon menu is expanded to contain the different configurations:
The default config.ini file contains common configurations, every other config file inherit from it.
To create multiple configuration files:
- stop the agent: tray bar icon -> pause then tray bar icon -> kill
- find the
config.inifile that is present in thearduino-create-agentinstallation folder - copy
config.inior create a new ini file (e.g.example.ini) with content:add in this file other configuration options (you can override inherited values fromname = your configuration nameconfig.ini) - restart the agent
- click the tray bar icon and select the new configuration
Tip: you can also use the multiple configurations feature to create a new configuration with the proxy settings. This way you can have multiple proxies configured and disable proxy configuration with ease.
The agent supports working behind a proxy, but manual configuration is required (there is no support for automatic proxy discovery).
To add proxy configuration:
- stop the agent: tray bar icon -> pause then tray bar icon -> kill
- find the
config.inifile that is present in thearduino-create-agentinstallation folder - copy
config.inito a new file (e.g.proxy.ini) with content:name = Proxy Enabled [env] http_proxy=your.proxy.here https_proxy=your.https.proxyhere
- please note spaces are not allowed before and after the string
http_proxy - restart the agent
- select the proper Proxy profile as in the image
- your agent will now work behind a proxy
- Type "Task Manager in the Windows Search Bar"
2. Select the Startup tab
3. Select the autostart file
4. Disable it
- Open Finder, click on Go menu, select 'Go to Folder'
2. Type the directory containing the autolauncher file, change with your Mac username, by default the directory is /Users/username/Library/LaunchAgents
3. Select the ArduinoCreateAgent.plist file
4. Right click on the file name and select 'Move to Trash'
The command line way:
$ launchctl unload ~/Library/LaunchAgents/ArduinoCreateAgent.plist
- Show hidden files
2. Select the .config dir in your home
3. Select the autostart dir
4. Move the file to the trash
The command line way:
Just remove the autostart file in your desktop manager, in Ubuntu is:
$ rm $HOME/.config/autostart/arduino-create-agent.desktop
To start manually the agent you can open the file at:
$ nohup $HOME/ArduinoCreateAgent-1.1/Arduino_Create_Bridge &
or in the location selected during the installation
Please use the current latest version:
The arduino create agent is a single binary that reads from a configuration file. Upon launching it will sit on the traybar and work in the background.
It will listen to http and websocket connections on a range of ports from 8990 to 9000.
You should make GET request to the /info endpoint on the possible ports, until you find a reply:
$ curl http://127.0.0.1:8990/info
curl: (7) Failed to connect to 127.0.0.1 port 8990: Connection refused
$ curl http://127.0.0.1:8991/info
�����
�����$ curl http://127.0.0.1:8992/info
{"http":"http://127.0.0.1:8992","https":"https://127.0.0.1:8991","version":"1.0.36","ws":"ws://127.0.0.1:8992","wss":"wss://127.0.0.1:8991"}
The reply will contain a json with info about the version and the http and https endpoints to use
Most of the commands can be performed with websocket instructions. We use a library called socket.io to handle the messages. Once you have the websocket endpoint you need you can:
var socket = io(endpoint);
socket.on('connect', function () {
socket.emit('command', yourCommand);
socket.on('command', function () {
// Your code to handle messages
})
}By clicking on the tray icon and going to the debug console you can try most of the websocket commands. The first command you should type in is:
log on
To get a json list of the connected boards you can issue the command:
list
You will receive an object of all the boards connected with USB or over the network:
{
"Ports":[
{
"Name":"/dev/ttyACM0",
"SerialNumber":"",
"DeviceClass":"",
"IsOpen":false,
"IsPrimary":false,
"Baud":0,
"BufferAlgorithm":"",
"Ver":"1.0.36",
"NetworkPort":false,
"VendorID":"0x2341",
"ProductID":"0x8036"
}
],
"Network":false
}{
"Ports":[
{
"Name":"192.168.1.101",
"SerialNumber":"",
"DeviceClass":"",
"IsOpen":false,
"IsPrimary":false,
"Baud":0,
"BufferAlgorithm":"",
"Ver":"1.0.36",
"NetworkPort":true,
"VendorID":"board=Arduino Y\\195\\186n Shield distro_version=0.1",
"ProductID":"Shield"
}
],
"Network":true
}To read input from a board connected to USB you must first open the port with the command
open /dev/ttyACM0 9600
where you should replace /dev/ttyACM0 with the actual port and 9600 with the baud.
You will receive a message like:
{
"Cmd":"Open",
"Desc":"Got register/open on port.",
"Port":"/dev/ttyACM0",
"IsPrimary":true,
"Baud":9600,
"BufferType":""
}or
{
"Cmd":"OpenFail",
"Desc":"Error opening port. Serial port busy",
"Port":"/dev/ttyACM0",
"Baud":9600
}You can then close the port with
close /dev/ttyACM0
You will receive a message like:
{
"Cmd":"Close",
"Desc":"Got unregister/close on port.",
"Port":"/dev/ttyACM0",
"Baud":9600
}or
{
"Error":"We could not find the serial port /dev/ttyACM0 that you were trying to close."
}While a port is open you can send input with
send /dev/ttyACM0 hello
with a reply like
{"Cmd":"Queued","QCnt":1,"Ids":[""],"D":["hello"],"Port":"/dev/ttyACM0"}
{"Cmd":"Write","QCnt":0,"Id":"","P":"/dev/ttyACM0"}
{"Cmd":"CompleteFake","Id":"","P":"/dev/ttyACM0"}You can receive output from the serial port by listening to messages like this:
{
"D":"output string\r\n"
}You can download a tool on the computer with a command like
downloadtool avrdude 6.0.1-arduino5 replace
receiving a reply like
{
"DownloadStatus": "Success",
"Msg":"Map Updated"
}The syntax of the command is:
downloadtool {{name}} {{version}} {{behaviour}}
where version can be a version number of the string "latest", and behaviour can be
"keep" (which skips the download if the tool already exists) and "replace" (which will download it again).
You can upload a binary sketch to a board connected to a port with a POST request to be made at the http endpoint.
The payload is a json object that looks like this:
{
"board":"arduino:avr:leonardo",
"port":"/dev/ttyACM1",
"commandline":"\"{runtime.tools.avrdude.path}/bin/avrdude\" \"-C{runtime.tools.avrdude.path}/etc/avrdude.conf\" {upload.verbose} -patmega32u4 -cavr109 -P{serial.port} -b57600 -D \"-Uflash:w:{build.path}/{build.project_name}.hex:i\"",
"signature":"97db97ced2c",
"hex":"OjEwMDAwMDAwMEM5NEU1MDAwQzk0MEQwMTBDOTQwRDAxMEM5NDBEMDE2MQ0KOjEwMDAxMDAwMEM5NDBEMDEwQzk0M",
"filename":"Blink.ino.hex",
"extrafiles": [],
"extra":{
"auth":{
"username":null,
"password":null,
"private_key":null,
"port":null
},
"wait_for_upload_port":true,
"use_1200bps_touch":true,
"network":false,
"params_verbose":"-v",
"params_quiet":"-q -q",
"verbose":true
}
}-
commandline is the command to execute to perform the upload. This is, for example, avrdude on a Leonardo.
-
hex contains the sketch hex encoded in base64
-
signature is the signature of the commandline signed with the private key that matches the public key contained in the config.ini of the arduino-create-agent
The results of the upload will be delivered via websocket with messages that look like:
{"Msg":"avrdude: verifying ...","ProgrammerStatus":"Busy"}
{"Msg":"avrdude done. Thank you.","ProgrammerStatus":"Busy"}
{"Flash":"Ok","ProgrammerStatus":"Done"}Please remember that for compile the project, you need go version <= 1.8.7 (more recent versions are not supported for compile)
To clone the repository, run the following command:
go get github.com/arduino/arduino-create-agent
This will clone the repository into your Go workspace or create a new workspace, if one doesn't exist. You can set $GOPATH to define where your Go workspace is located.
Now you can go to the project directory and compile it:
cd $GOPATH/src/github.com/arduino/arduino-create-agent
go build
This will create the arduino-create-agent binary.
Other prerequisites are:
- libappindicator (Linux only on Ubuntu
sudo apt-get install libappindicator1) - [go-selfupdate] (https://github.com/sanbornm/go-selfupdate) if you want to test automatic updates
Please attach the output of the commands running at the debug console if useful.
