How to connect to the default MQTT network
The default network, which is automatically created with a Hub, is a MQTT network. The a default network, cannot be deleted.
- You have an account and are logged into the Scaleway console
- You have created an IoT Hub
Add a Hub device if you haven’t already done so.
To keep this tutorial simple, choose toAllow Insercure
connections. Insecure connections allow connections to the hub without encryption layer.Configure the physical device (or client) to connect through the network, using the following parameters:
- Host: The network endpoint.
- Port: Use
1883
for plaintext or8883
for TLS. - MQTT Username: The device ID from the device you created earlier.
- If your client asks for a password, just pass in an empty string.
Note:If you have configured your device to force mTLS (
Deny Insecure
connections), you will also need to provide the device certificate & private key, so that during the TLS handshake, the Hub will be able to verify the device identity.Connect and exchange messages.
Some networks support topic prefixes, but the default networks do not. The whole “topic space” is available to MQTT clients.
