Test Objective

To verify that a Bluetooth module, HC-06 and a cell phone are able to communicate within a distance of 10 feet +/- 0.5 feet.

Tools

Figure 1 indicates that a measuring tape is needed to verify this test.

Procedure

Setup the Bluetooth module, Arduino and a LED.  Verify that the code is uploaded to the Arduino and begin.

1.Lay the measuring tape and create a distance of 10 feet.

2. Starting at 1 foot away from LED, turn the LED on and off with your phone to insure you are connected.

3. Move away 0.5 feet and again turn the LED on and off to insure you are connected.

Figure 6: Results

In our requirements the Bluetooth module must have a range of at least 10 feet; from our verification test, we have met this requirement.  Trial 4 was a test to verify our max range and 27 feet was the maximum range we could physically move away from the Bluetooth module while remaining in the same room.
