Crate clyde_3g_eps_service

Service for interacting with a Clyde Space 3G EPS

Configuration

The service can be configured in the /home/system/etc/config.toml with the following fields:

[clyde-3g-eps-service]
bus = "/dev/i2c-1"

[clyde-3g-eps-service.addr]
ip = "127.0.0.1"
port = 8089

Where bus specifies the I2C bus the EPS is on, ip specifies the service's IP address, and port specifies the port on which the service will be listening for UDP packets.

Running the Service

The service should be started automatically by its init script, but may also be started manually:

$ clyde-3g-eps-service
Listening on: 127.0.0.1:8089

If no config file is specified, then the service will look at /home/system/etc/config.toml. An alternative config file may be specified on the command line at run time:

$ clyde-3g-eps-service -c config.toml

Panics

Attempts to grab bus from Configuration and will panic! if not found.

GraphQL Schema

Queries

ACK

Fetch the last mutation which was executed by the service. Returns a subsystem::Mutations value.
