Here you find a short description of how to send data.

WORK IN PROGRESS

Creating a new device in Cumulocity

If you'd like to try, you don't have to do this part. Contact us with a UUID and we will provide you with a set of credentials to access the UBIRCH API.

1. create a UUID (uuidgen)
2. in Cumulocity, register a new device using that UUID
3. run the script create_device_credentials.sh <PWD> <UUID> using the bootstrap password
4. accept the device in Cumulocity and wait for the script to exit
5. write down the device username and password

Running the Client

Set up the environment variables required:

• UBIRCH_ENV - (dev, demo, prod)
• AUTH_USER - the user name from above
• AUTH_PASS - the password from above
• CLIENT_UUID - the uuid created above
• CLIENT_KEY - base64 encoded signing key (Ed25519)

---

• SERVER_UUID - (optional) the corresponding backend
• SERVER_PUBKEY - (optional) base64 encoded public key UUID

Run UbirchClient which sends one message to Cumulocity and a UPP of the data to the configured UBIRCH backend.
