Follow these steps to start the firmware on the sensor and collector nodes. Refer to Section 3.1.1 for instructions on setting up the sensor node hardware.
- Power on the collector node (CC1352 only) with the USB power supply first, and then wait for the red LED "Red: DIO6" to be on.
- Power on the sensor node (IWR6843 boards + CC1352) with 5.0-V power supply
- Reset the sensor node by pressing the SW2 (NRST) button on the MMWAVEICBOOST board (see Figure 3-11).
- Press "BTN-2 DIO14" (on collector node) to permit nodes to join the network, the "Red: DIO6" LED should be blinking on the collector node to indicate the network is opened.
- Once the sensor has joined the network, its red LED will turn on.
- Press "BTN-2 DIO14" (on collector node) to stop permitting new nodes from joining the network.
- Once the sensor node has joined a network and has waited 20 seconds for the IWR6843 device to power up, the CC1352 device will configure and start the mmWave.
- On both sensor and collector nodes, the "Green: DIO7" LED will toggle on each successful transmission between the nodes.
