| - | **=== Mesh Network Set up ===** | + | **=== 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 | ||
