The Particle Mesh gateways use the nRF52840 SoC’s Thread capability to communicate with other Thread devices on the mesh network while the Bluetooth LE connectivity allows developers to use Bluetooth 4.0 (and later) smartphones and tablets for mesh set-up, deployment, and diagnostics in the field.
The Particle Mesh development kits are pre-configured to fully integrate with Particle’s ‘Device Cloud’, a unique set of development tools and Cloud infrastructure, to build, connect, and manage mesh networks.
Nordic’s nRF52840 Bluetooth LE SoC is Nordic’s most advanced ultra low power wireless solution. The SoC supports complex Bluetooth LE and other low-power wireless applications that were previously not possible with a single-chip solution. The SoC combines the Arm processor with a 2.4GHz multiprotocol radio architecture featuring -96dB RX sensitivity and an on-chip PA boosting output power to a maximum of 8dBm. The SoC is supplied with the S140 SoftDevice which supports concurrent Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles.
“We selected Thread over other mesh networking solutions because of its maturity in market, ability to scale to large networks, use of open standards, and the availability of open source implementations,” says William Hart, General Manager of Prototyping at Particle. “Bluetooth LE is also a critical component of Particle Mesh and bidirectional communication between a smartphone and the Particle Mesh device to simplify device setup, deployment, and diagnostics. Because we needed both Thread and Bluetooth LE support, Nordic’s nRF52840 SoC was an ideal choice for our new Particle Mesh hardware solutions.
“We’re also excited to be working with the Nordic team, who have provided us with technical information and examples, direct support from design to production, and access to global distribution partners.”
