serial-gateway

A serial gateway that runs in the cluster. It will read a serial port mounted from the node and process the messages received

Virtual Serial

Taken from this stackoverflow post

To test, in one terminal run the following to create a virtual serial device.

socat PTY,link=./virtual-tty,raw,echo=0 -

Then you can run this in a different terminal to read from the device. Now you can type input into the first terminal, hit enter to make it available in the serial gateway.

SERIAL_PORT=./virtual-tty go run cmd/serial/main.go

Pub

The serial-gateway has a /pub endpoint that can be used for testing. A POST to /pub will result in the http body being written to the serial port on the host. As a result the LORA gateway will broadcast the contents for any LORA device to receive.

ssh -D 9995 weeble
kubectl ctx weeble-admin
kubectl -n serial-gateway port-forward svc/serial-gateway 8080:8080

curl -X POST "http://localhost:8080/pub" -d "a-message" 

## or
curl -X POST "https://serial-gateway.tonygilkerson.us/pub" -d "GatewayHeartbeat:1234" 
curl -X POST "https://serial-gateway.tonygilkerson.us/pub" -d "MailboxDoorOpened:1" 

for i in $(seq 100); do
  echo "Post MailboxDoorOpened:$i"
  curl -X POST "https://serial-gateway.tonygilkerson.us/pub" -d "MailboxDoorOpened:$i"
  sleep 7
done
