| + | * 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 | ||

| + | * 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 | ||
