Agents keep track of the Clients and the Micro XRCE-DDS Entities they create. The Agent uses the Entities to interact with DDS Global Data Space on behalf of the Client. The communication between a Micro XRCE-DDS Client and a Micro XRCE-DDS Agent supports three kind transport: UDP, TCP, or SerialPort. While running Micro XRCE-DDS Agent will attend any received request from your Micro XRCE-DDS Clients. Micro XRCE-DDS Agent answers back with the result of a request each time a request is attended. The Agent supports being run by the user like this: ``` $ micro-xrce-dds-agent --help ``` In addition, the Agent supports running as a service that can be enabled with: ``` $ snap set micro-xrce-dds-agent daemon=true ``` If the service is enabled, by default it uses the `udp4` transport on port 8888. The following parameters can be changed (these are specific to the service, the `micro-xrce-dds-agent` command simply takes command-line arguments, but the capabilities are the same): * `transport`. Supported transports are `udp4`, `udp6`, `tcp4`, `tcp6`, `serial`, and `pseudoterminal`. Default is `udp4`. Change with: ``` $ snap set micro-xrce-dds-agent transport="new transport" ``` * `middleware`. Supported kinds of middleware are `ced`, `rtps`, and `dds`. Default is `dds`. Change with: ``` $ snap set micro-xrce-dds-agent middleware="new middleware" ``` * `verbosity`. Supported verbosity levels are 0-6, defaulting to 4. Change with: ``` $ snap set micro-xrce-dds-agent verbosity="selected verbosity" ``` * `discovery`. Enable or disable the discovery server. Defaults to "false". Change with: ``` $ snap set micro-xrce-dds-agent discovery="true or false" ``` * `discovery-port`. Port on which the discovery server (see above) listens. Defaults to 7400. Change with: ``` $ snap set micro-xrce-dds-agent discovery-port="selected port" ``` * `p2p-port`. Port to use for the P2P profile. Change with: ``` $ snap set micro-xrce-dds-agent p2p-port="selected port" ``` * `port`. Port on which the agent listens. Only applicable to one of the UDP or TCP transports (see above). Defaults to 8888. Change with: ``` $ snap set micro-xrce-dds-agent port="selected port" ``` * `baudrate`. Baud rate to use when accessing serial ports. Only applicable when using the `serial` or `pseudoterminal` transport. Defaults to 115200. Change with: ``` $ snap set micro-xrce-dds-agent baudrate="baud rate" ``` * `device`. The serial device to use. Only applicable when using the `serial` or `pseudoterminal` transport. Change with: ``` $ snap set micro-xrce-dds-agent device="device path" ``` When using the snap with a serial device, some steps need to be taken in order to establish a successful connection: + Refresh your local installation of the snap `core` package: ``` $ sudo snap refresh core --edge ``` + Enable the hotplug feature and restart the `snapd` daemon: ``` $ sudo snap set core experimental.hotplug=true $ sudo systemctl restart snapd ``` + After plugging the microcontroller to the serial port, execute the `snap interface serial-port` command. You should see something like this: ``` name: serial-port summary: allows accessing a specific serial port plugs: - micro-xrce-dds-agent slots: - snapd:cp2102cp2109uartbrid (allows accessing a specific serial port) ``` + Connect your snap image to the desired serial port (replace accordingly): ``` $ snap connect micro-xrce-dds-agent:serial-port snapd:cp2102cp2109uartbrid ``` After this, you can execute your snap as usual, using `micro-xrce-dds-agent serial -d `. --- ## Install Micro XRCE-DDS Agent on your Linux distribution Choose your Linux distribution to get detailed installation instructions.
