| - | ==== Configuring the node ==== | + | [[doc: |
| - | The node can be used as: | ||
| - | * An anchor: receives and answer ranging requests | ||
| - | * A tag: Ranges with anchors and prints the distance | ||
| - | * An UWB sniffer: Prints all messages received from the radio | ||
| - | |||
| - | To configure the node connect it to a computer (I will assume a computer running linux but it should work on mac and windows as well). The node will be recognised as a serial port. The name of the serial port can be found with // | ||
| - | $ dmesg | ||
