I have configured an MQTT sparkplug EoN device profile. I configured Basic MQTT authentication. I have defined clientID, user and password to match. I cannot get it to connect at all to mqtt.thingsboard.cloud:1883. Port is open and telnet confirms is correct. What could I be doing wrong. These devices are existing and already were publishing to MQTT SparkplugB correctly.
topic GROUP/DDATA/NODE/DEVICE but I cannot figure out what they are looking for in the topics? How do they expect the EoN device ID to be. For a moment, the device shows active in Thingsboard cloud. But no telemetry is ever read.
