2. A connection to the BLE & 3G Gateway ATEX server is established if the BLE pairing between the
BLE Gauge sensor modules and the BLE & 3G Gateway ATEX was successful.
3. The data is synchronised with the myDatanet server.
8.3.2 Connecting the GSM antenna
Important note:
To ensure the correct functionality, only use antennas that are supplied by the
manufacturer.
The standard antenna is directly connected to the antenna connector (see "Overview" on page 27) of the
myDatalogGauge 3G .
1. Connect the connection cable of the antenna directly to the antenna connector of the myDatalogGauge
3G (see "Overview" on page 27).
The following step is not mandatory.
2. Check whether the connection to the myDatanet has worked correctly (see "Testing communication
