**=== Mesh Network Set up (Many-To-One) ===**
  * Configure all three remote devices
       * add all three XBees (Coordinator, relay and router)
       * update the firmware of each module
            * Function Set: DigiMesh 2.4 TH PRO
            * Firmware Version: Newest value
       * Configuring the first device (Coordinator)
            * First click the default parameter setting 
            * Then change these parameters 
                 * ID: 7FFF 
                 * NI: SENDER
                 * API: API enabled [1]
                 * **IMPORTANT:** there is already an empty space in NI, so be sure to delete that before naming module
       * Configuring the second device (can be the router or relay XBee)
            *  Click the default parameter to reset parameters
            * Change parameters to:
                 * ID: 7FF
                 * NI: Relay_1
                 * API: Transparent Mode [0] ( or you can do 1, we just left it at 0)
           * Write the radio settings
       * Configure the third device exactly the same as the second device. Setting NI as Relay_2
       * Disconnect both the relay and router XBees  and put them into their own power supply (we used two laptops)
           * Each module should be plugged into their own power supply by now
           * Radio modules should only contain the coordinator now  
       * Using the laptop that has the coordinator, select the coordinator, and click the "discover the radio nodes in the same network 
       * add all selected devices (relay and router Xbees) in the discovering remote devices 

**=== Testing the XBees Communications ===**
  * Using the laptop containing the coordinator (API 1 XBee or SENDER):
       * Wirelessly connect to Relay_1 and Relay_2
       * Place laptop at one end of hallway 
  * Using the laptop contained the router (Relay_1):
       * Open up XCTU program
       * Place laptop in between SENDER and Relay_2:
  * Using the laptop contained the second router (Relay_2):
       * Start up XCTU
       * Place laptop past Relay_1
  * After finishing the placement of the three XBees communicate from Relay_2 by creating packets
       * Relay_1 should receive the packets as ASCII values
       * SENDER should receive the packet as ASCII values and also the address of Relay_2
  * After verifying that all 3 Xbees are communicating start a range test with SENDER computer 
       * In range test, select sender address and Relay_2 address
       * Increase distance as far as possible 

**=== Testing with PCB ===**
  * Place Relay_1 XBee on PCB
  * Connect PCB to battery
  * Same configuration of XBees similar to above where starting from beginning it will be: Sender->Relay_1->Relay_2
  * Start by sending packets from Relay_2 and see if Sender is receiving packets
  * Start range test with Sender computer
  * Complete range test
