Charging beacons and other details
-
The Beacon has 5 sensors (transducers) RX1, RX2, RX3, RX4, RX5
-
DIP switch modes:
1) Power OFF, DFU OFF: charging is possible; beacon is disconnected from power. This
mode is recommended, if you want to keep the battery fully charged for many months
2) Power ON, DFU OFF: normal working mode for beacon. The beacon is fully powered
and wakes up every a few seconds. Power consumption is still minimal, if the beacon
sleeps and the battery can last for many weeks or a few months. It is recommended to
keep the beacon in this mode and to not touch the DIP switch at all, unless you want
to store the beacon on the shelf. Then, the mode 1) is better and recommended
3) Power ON, DFU ON: DFU programming mode. It is used for the very initial SW
uploading or when the HEX SW cannot be uploaded from the Dashboard for some
reasons
