BT840E Advanced Features
Bluetooth 5 datarate: 2Mbps, 1Mbps, 500 Kbps, 125 kbps
IEEE 802.15.4 Thread and Zigbee
Nordic 2.4 GHz proprietary
1.7V to 3.6V DC power supply
High voltage power supply to accept up to 5.5V DC for direct connection to Lithium batteries or 5V system power. An external voltage regulator is not required. Your total system cost can be lower and your PCB size can be smaller. (To be supported by Rev D silicon)
Range between two BT840Es is estimated at over 900 meters.
Embedded CryptoCell 310 co-processor can be used to provide more secure connection and to prevent hacker.
BT840 is required if your Bluetooth 5 devices are used in mesh networks with many nodes. Security is mandatory in Bluetooth mesh networks. By offloading decryption, encryption, and authentication works to CryptoCell-310, BT840E can deliver high performance in Bluetooth mesh networks.
