Hello,
We are currently trying to connect a Teltonika FMC650 to our MQTT broker (Mosquitto-based).
We have configured the MQTT server address and port, and we have successfully uploaded the Root CA, client certificate, and private key to the device.
The TLS handshake completes successfully and the certificates are exchanged correctly. However, the connection is then rejected by our MQTT broker because our broker requires MQTT username/password authentication.
In the FMC650 MQTT configuration (AWS IoT Custom mode), we cannot find any option to configure a MQTT username and password.
Is there a way to configure MQTT username/password authentication on the FMC650 for MQTT connections?
If this is not supported, is there an alternative authentication method recommended for connecting the FMC650 to a standard Mosquitto broker that requires both TLS certificates and MQTT credentials?
Thank you for your support.
