BT832, BT832F, and BT832X

 

The Best Solution for Mesh Networks

Hard to reach nodes are likely in mesh networks. BlueNor BT832 Series modules are the best solution for mass deployment in mesh networks.

  1. Develop your products using BT832, the lowest cost module with Cortex M4F.
  2. Upgrade with BT832F when 220 meters range is required.
  3. Upgrade with BT832X when 1170 meters range is required.
  4. Upgrade with BT832XE with an external antenna is required when 1350 meters range is required.
  5. Upgrade with BT840F when support for IEEE 802.15.4 Thread or Zigbee is required.
  6. Reduce cost by using BT832A (nRF52810 module) if 192KB flash/24KB RAM is enough.

With Bluetooth 5 mesh network protocol stacks and BlueNor BT832 Series modules, no hardware or firmware redesign is needed to reach any node in mesh network. For wide area mesh network, BT832X can be used as a repeater.

Using BlueNor BT832 Modules in Bluetooth 5 Mesh Network

Using BlueNor BT832 Modules in Bluetooth 5 Mesh Network

For products not used in a mesh network, BT832 is still the lowest cost, certified module with a Cortex M4F processor. This is our guarantee.

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. Two nodes (evaluation boards) are used for range measurements.

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 B.
  5. Rotate Node A by 30 degrees and take 12 total measurements. Minimum and maximum ranges are listed below.

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.

Upgradeable Bluetooth Range

To accommodate high performance antenna and power amplifier, physical sizes of BT832 Series modules are different. However, the soldering pad footprint is identical for all modules. Bluetooth range can be upgraded by replacing module only. No change to main board hardware and firmware is required (about 100 mA DC current is required for BT832X). Multiple versions of the same product can be made to meet various range requirements for mass deployment in mesh networks.

All nRF52832 GPIO pins can be accessed by either castellated pins or LGA pins.
