About test

Data reading and writing examples here below assumes that you are using the Eclipse Mosquitto client CLI, available at the official page https://mosquitto.org

Code placeholders

Code here follows uses placeholders that must be replaced with the actual values. So you should know in advance these variables:

• <realm-id>: identifier of the organization (see Get organisation-id)

• <device_id>: identifier of the machine (see Get device-id)

machine ssl certificates names, contained in the zip file (see Get ssl certificates )

• <certificate_crt>: named as xxxxxxxxxxxx-certificate.pem

• <private_key>: named as xxxxxxxxxxxx-private.pem

• <cafile_crt>: AmazonRootCA1.pem is the current file name

Publish data

timestamp must be expressed in milliseconds Sent data by here below snippet are: Cabinet_probe: 55, Evaporator_probe: 85
