How does the logger react if it cannot establish a UMTS/LTE connection to the server (e.g. no SIM card; deadlock)?

The logger starts several attempts to connect to the server. If no connection can be established, the logger terminates after the maximum transfer cycles/duration of the transport configuration. The transfer duration can be set in Uniconf under the properties of the transport configuration.

The connection attempts are logged in the (extended) log file of the logger. In addition to other entries, the "SignalStrength" indicates the quality of the radio network. If this value is less than or equal to 10, the reception is too poor.
