**=== Using the XCTU Program: ===**
  - Make sure everything is connected: wires, code is correct
  - Make sure all Xbees recognize one another (close the plug(+)
  - Make sure coordinator receives packets so you know that relay and sending Xbee works
  - XCTU Program
     *Tools -> range test
     *Select remote radio device: relay Xbee
     *Can choose how many packets to send (usually 15)
     *Start Range Test after

**Notes:**

Upload Sending Code to Router/Sending XBee (Change to Relay Address)
  - Put Xbee on Xbee shield and arduino
  - Set shield to "Dline"
  - When done uploading code, set back to "UART"

Upload Relay Code to ATmega 328P (Change to Coordinator Address)
  - Use FTDI, connect wires to corresponding pinouts on ATMega barebumblebee
          * RTS - Reset
          * RX - TX
          * TX - RX 
          * VCC - Power rail
          * CTS unplugged
          * GND to Ground
  - Power supply should only be FTDI (unplug battery)
  - Arduino Setting (tools)
          * Board: Arduino/Genuino Uno
          * Port: (Select)
          * Programmer: "Arduino as ISP" {for bootloading} or "AVRISP mkll" {for uploading code
Note: Make sure FTDI's DTR is connected to the capacitor not Pin 1 of ATmega328p.
LED on XBee should be on; not blinking?

**=== Range Testing w/ PCBs ===**
  * Connect solar charging chip and relay xbee onto the PCB board (we used v4.0)
  * Connect battery into the solar charging chip (Batt)
  * Plug coordinator into computer
  * Open XCTU program and click discover devices 
  * Select all ports and then click 'next'
  * Dont change anything from "set port parameters" window; click 'Finish'
  * Make sure coordinator is found; Mac Address: 0013A20041287FF9

  * Click on select all device and then add select device
  * Looking at the "Radio Module" side, looking at coordinator, click on discover remote devices
  * Make sure Relay Xbee is identified; select all and then click select devices
{{ :weatherbox:bumblebee:screen_shot_2021-03-07_at_11.34.21_am.png?400 |}}
  * Click on tools icon and select 'range testing'
  * Click 'select local device": should say something like zigbee
  * Make sure remote selection says ...FFB (Relay xbee)
  * Change number of packets to 15
  * Start Range Testing!
