This project is able to ingest LoRa (TTN) uplink messages and forward them to a PubSub topic.
- A Google project, with enough credentials to have some fun
- A Linux PC
- Go 1.15 installed
- gcloud installed
- A PubSub topic, create it and note the name.
First create a .env file in the root of the project with the following contents:
PROJECT_ID="<your google project id>"
ROOT="agritech"
ACCESS_TOKEN="<an access token>"
TARGET_TOPIC="projects/{projectId}/topics/<the topic you created>"
To access that pubsub topic inspect and run from the root of the project you need to create a service account:
./scripts/create_service.sh
If all is well, a json file is generated that provides your local development environment access to the PubSub topic.
From the root of the project, run:
./scripts/debug.sh
The Docker image is built and run, output should be alike:
{"level":"info","msg":"listening on port :8080","time":"2020-11-27T22:00:10+01:00"}
➜ lora-ingress-http-go git:(master) ✗ ./scripts/submit.sh
