A list of added sensors will be shown in the sensor connection card.

Please note that the maximum 7 LPMS-B2 can be connected to the logger simultaneously due to bandwidth limitation of bluetooth

Sensor Scanning

Sensor scanning feature is added to logger with UI version >= 1.1.1 Server version >=1.1.4. Press “Scan” to automatically list available LpmsB2 sensors. Please note that scanning might take up to 20s to complete. User can still manually key in the sensor ID in the input space.
