The NASA Battery Viewer displays the battery monitor information in a clear and simple way. The app allows you to configure which fields are displayed and where, allowing you to choose the most important field as the primary field. The charging/discharging display field will appear in red when discharging. The app also allows you to set the unit's properties (capacity, operating temperature, unit name). The app communicates with the BM-1 unit over Bluetooth LE. It will automatically connect to your BM-1 unit with the configured Bluetooth name. If the unit's name doesn't match any BM-1 units in range will be offered to you so you can choose to connect. The unit rename feature allows you to assign your own name to your BM-1 unit.
