NSL Duplex Communications Service

This communications service provides communications functionality over the NSL Duplex radio.

Running

This service expects a service configuration file in either the default location or to be passed in at runtime like so cargo run -- -c config.toml.

The service expects the following sections and settings to be present:

# Service specific configuration
[nsl-duplex-comms-service]
# Serial bus to use for talking with the radio
bus = "/dev/ttyUSB0"
# Specifies how frequently the service sends ping packets when the downlink queue is empty (seconds)
ping_freq = 10

# GraphQL configuration
[nsl-duplex-comms-service.addr]
# IP to bind GraphQL server to
ip = "127.0.0.1"
# Port to listen on for GraphQL queries
port = 8140

# Communications service configuration
[nsl-duplex-comms-service.comms]
# Maximum number of concurrent message handlers
max_num_handlers = 10
# Ports to listen for local traffic on
downlink_ports = [14011]
#  Timeout when listening for packet response (milliseconds)
timeout = 1
# IP to bind Communications service listener to
ip = "0.0.0.0"

When the service has started correctly it will display output like so:
