Arad MN52H (Nordic nRF52840) BLE Module Range Test

1. Test Objectives

· Verify the effective communication range of the MN52H BLE module in open field conditions.

· Compare communication performance among different antenna types (CHIP / PCB / u.FL).

2. Test Environment

Outdoor Environment：Open and unobstructed area (Line-of-sight)

3. Equipment Required

· BLE Signal Transmitting Device (Emitting Board)

o Test Modules：MN52H-C40, MN52H-P40, MN52H-U40

· BLE Signal Receiving Device

o Test Device: iPhone 7

· Testing Software: LightBlue®

· Distance Measurement & Logging Tools: Google Maps, smartphone GPS positioning

4. Test Parameters

5. Test Procedure

1）Establish a stable BLE connection between the iPhone 7 and the transmitting module, and confirm packet reception.

2）Record transmission success rate at the starting point.

3）Stay at each distance point for at least 10 seconds and log connection quality.

4）Test the impact of different transmission angles on range performance.

5）Conduct at least three test runs to verify consistency.

6） When the connection drops, record the disconnection distance and surrounding environmental conditions.

6. Test Records / Results

· Maximum distance comparison under different transmission angles

· Performance comparison table for each antenna type

· Device version and firmware information used in testing

· Anomaly logs (e.g., packet loss incidents)
