Measuring Bluetooth Ranges in Mesh Networks

Bluetooth Mesh Evaluation board is preloaded with mesh protocol testing firmware. Up to 65536 nodes are supported. Each node can be addressed and controlled by smartphone. 

Bluetooth range between a pair of BC832 is shorter than between a phone and a BC832. A different firmware is required to measure the range between  a pair of BC832.

Procedures for measuring Bluetooth ranges.

1. Download BlueNor Mesh User Manual from the DOWNLOAD section below.

2. Download BlueNor Mesh APK from Google Play Store.

3. Follow Procedures to Send Message in Mesh Network in the manual.

4. Test for the maximum range to receive an ACK from node A.

Enclosure of final product will reduce Bluetooth range. Interference from other wireless sources, walls, and other physical objects will also reduce Bluetooth range. Bluetooth range in end user environment will be shorter.

Datasheets, certificates, evaluation board schematics are available for download.

Evaluation Board EV BC832

EV BC832 is preloaded with BlueNor nRF5x application and SoftDevice S132 V5.0.0 Bluetooth 5 stacks. It can be used with Android app BlueNor nrf5x available at Google Play Store. You can send commands from an Android phone to toggle LED light on evaluation board. You can also send button pressing signal from evaluation board to Android device. 

SDK and Android app source codes are available for download in the Bluetooth 5 Codes section of Download BlueNor Document. Other application codes can be downloaded from the same webpage.

To load other codes or to develop your own, a Nordic nRF52 DK is required but not included.
