BT832X

 

BT832X, Bluetooth 5 Module with Power Amplifier

BT832X is a Nordic nRF52832 module with Skyworks SKY66112 power amplifier. With over 120 dB link budget, range is 1300 meters when antenna on BT832Xs is facing each other. When one antenna is rotated 30 degrees after each measurement, average range for 12 measurements is 1170 meters.

BT832XE, Bluetooth 5 Module with Power Amplifier and an u.FL Connector

BT832XE is a Bluetooth 5 module with nRF52832, SKY66112 power amplifier, and an u.FL connector for an external antenna. Bluetooth range with an +6 dBi external antenna is 1350 meters for all angles when one antenna is rotated by 30 degrees after each measurement.

The external antenna is omni directional.

Procedures for Measuring Bluetooth Ranges

Evaluation board EV-BT832X/BT832XE is loaded with Master or  Slave firmware for range measurement. A Slave board can be connected to a smartphone and up to 4 Master boards. A smartphone is not required for measuring range between 2 Bluetooth modules.

Using Evaluation board with Master and Slave Firmware to measure Bluetooth range

Using Evaluation board with Master and Slave Firmware to measure Bluetooth range

A Slave board and a Master board are required for range measurement.

  1. Powering up both Master and Slave boards. Portable smartphone charger is recommended.
  2. LED 2 is ON to indicate connection between Master and Slave.
  3. Each board sends a command every second.
  4. LED 4 toggles ON/OFF when a valid Bluetooth command is received. A consistent toggling of LED light is an indication for almost error free data reception. When signal is weak or interference is high, some toggling is missed.
  5. Measure the range that LED 4 stops toggling for a few seconds.
  6. Rotate one board by 30 degrees and take 12 total measurements. 

Testing Conditions

We test ranges of BT832X and BT832XE in a farmland east of Scottsdale, Arizona USA. Testing conditions:

  1. One evaluation board on a long wood stick supporting by a ladder. Antenna is 7 feet or 2.1 meters above ground.
  2. A tester holds the short wood stick with the second evaluation board. Antenna is about 2.1 meters above ground during testing. The second evaluation board is rotated by 30 degree after each measurement.
  3. Wireless interference is relatively low in this area.
  4. A car or a truck can blow dust up and block Bluetooth signal.
  5. "Track Exercise" feature of Fitbit app on an iPhone 6 Plus is used to measure distance. Resolution is 10 meters. Human steps are used to measure distance with resolution to 1 meter in some cases.

Testing Results

We measure Bluetooth ranges with the following evaluation boards.

  1. 6 Master-Slave pairs of EV-BT832X boards
  2. 1 Master EV-BT832XE with a +6dBi external antenna and 2 Slave EV-BT832XE with a +6dBi external antenna.
  3. 1 Master EV-BT832XE with a +6 dBi external antenna and 3 Slave EV-BT832X.

The followings results are average of these measurements. In summaries:

  1. The external antenna is omni-directional. Range is 1350 meters for all angles between 2 BT832XEs with external antenna.
  2. Range between a BT832XE with an external antenna and a BT832X is almost omni directional. Range is more than 1345 meters for all angles.
  3. BT832X antenna is not omni directional. Range between 2 BT832X is from 1067 meters to 1322 meters. Or, range is  1174 meters on the average.
Bluetooth Line of Sight Range between BT832X and BT832XE.

Bluetooth Line of Sight Range between BT832X and BT832XE.

BT832X is usually installed inside a enclosure. Interference from other wireless sources, walls, and other physical objects will also reduce Bluetooth range. Bluetooth range in end user environment will be shorter.

Additional Testing Notes

  1. The antenna on the fixed wood stick is always 2.1 meters above ground. If the second antenna is lifted to about 3 meters, Bluetooth range is longer.
  2. We tested BT832XE with +9dBi and +12 dBi external antennal. The range is just a few meters longer. Multiple-path interference can be the dominating limiting factor.
  3. If our speculation is true, Bluetooth range can be much longer if at least one antenna is high above ground. An example is drone application.
