BT832 Series BLE, Bluetooth 5 Module
The Best Bluetooth 5 and Mesh Network Solutions
Hard to reach nodes are likely in mesh networks. BlueNor BT832 Series Bluetooth 5 modules are the best solution for mass Bluetooth 5 deployment and for use in mesh networks.
Develop your Bluetooth 5 products using BT832, a low cost Bluetooth 5 module with Cortex M4F, $5 each at 1 pcs.
Upgrade with BT832F Bluetooth 5.0 module for 760 meters average range, at 7.5 mA peak current.
Upgrade with BT832X (nRF52832 + power amplifier module) for 1140 meters average range.
Upgrade with BT832XE (nRF52 832 + power amplifier + u.FL module), when an external antenna is required. BT832XE is the longest range Bluetooth 5 module, 1350 meters, omni directional
Upgrade with BT840F (nRF52840 module), Bluetooth 5, Thread, Zigbee, CryptoCell 310 co-processor, 2300 meters range at 125 Kbps, 13.6 mA peak current.
Upgrade with BT840E (nRF52840 + u.FL module), Bluetooth 5, Thread, Zigbee, CryptoCell 310, 13.6 mA peak current.
Upgrade with BT840 (nRF52840 module), a lower cost, smaller size, shorter range alternative of BT840F.
Reduce cost by using BT832A (nRF52 810 Bluetooth 5 module), 192KB flash/24KB RAM, no NFC, $3.75 each at 1 pcs.
Reduce cost and increase range by using BT832AF (nRF52810 module), 192KB flash/24KB RAM, no NFC, 760 meters average range.
With Bluetooth 5 mesh network protocol stacks and BlueNor BT832 Series modules, no hardware redesign is needed to reach any node in mesh network. A host board design can accommodate all modules listed above. For wide area network, BT832X can be used in Relay node. For mesh networks with many nodes, BT840F with CryptoCell-310 co-processor is recommended for Relay node.
Open Source Bluetooth 5 Devices
With market ready enclosure, you can begin marketing WiFi to BLE IoT gateway or BLE 5 sensor upon completion of firmware and software development.
If you wish to develop your own products, use these WiFi to BLE IoT gateway and Bluetooth 5 sensor as examples for PCB layout, placement of mechanical components to reduce attenuation and interference of BLE signal for longer range.
Bluetooth Range Measurements
Bluetooth range measurement site, methods, and results for long range modules are available.
11 Modules, Compatible Footprints for Upgradeable Memories, Features, Bluetooth Ranges
To accommodate high performance antenna and power amplifier, physical sizes of BT832 Series are different. However, the soldering pad footprint is identical for all modules. BT840 Series' footprints are superset of that of BT832 Series. Bluetooth range, memories, and features can be upgraded by replacing module only. No change to main board hardware is required. Multiple versions of the same product can be made to meet various requirements for mass deployment in mesh networks.
