BLE 5 Modules, BT840XEE
BluNor BT840XEE is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic nRF52840 SoC. With
an ARM Cortex
TM
M4F MCU, available 1MB flash, 256KB RAM, embedded 2.4GHz multi-protocol transceiver and a power
amplifier. An u.FL and an MCX connectors for external antenna connection. It allows faster time to
market with reduced development cost.
Bluetooth ranges are measured in environments with Low Multiple Path Interference (LMPI) and
antenna at 5 feet (1.52 meters), typical height of thermostat in the USA. Ranges for LMPI,
correlating to actual link budget, indicate the Bluetooth signal strength for penetrating walls in
buildings.

For full description of the SoC, please download from Nordic Semiconductor website. https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy Block Diagram of nRF52840 The following is a block diagram of Nordic nRF52840 Bluetooth Low Energy (BLE) SoC. Arrows with white heads indicate signals that share physical pins with other signals. - Page 6 BLE 5 Modules, BT840XEE Ver 0.99 Sep. 2022 The 32 bit ARM Cortex M4F MCU with hardware supports for DSP instructions and floating point operations, code density and execution speed are higher than other Cortex M MCU. The Programmable Peripheral Interconnect (PPI) system provides a 20-channel bus for direct and autonomous system peripheral communication without CPU intervention. This brings predictable latency times for peripheral to peripheral interaction and power saving benefits associated with leaving CPU idle.

Page 18: Bluetooth Range
Bluetooth range measurement reports and hex codes used in measurements can be downloaded from Bluetooth Range Measurements section of this webpage. Settings for passing FCC certification testing is used. http://www.fanstel.com/download-document/ Bluetooth ranges are measured between 2 modules on evaluation boards for various height of antenna. On the first measurement, both antennas are pointing to sky and facing each other. - Page 19 BLE 5 Modules, BT840XEE Ver 0.99 Sep. 2022 • Low Multiple Path Interference (LMPI). For longer range measurement, antenna must be higher to have LMPI. To have LMPI, 60% clearance is required. For example, if transmitter and receiver is 1000 meters away, both antennas must be 3.33 meters above ground and away from any obstruction.
- Page 20 • nRF52840 receiver sensitivity is -103 dBm at 125 Kbps per Nordic product specifications. • SKY66112 receiver gain is measured at 1.5 dB by Fanstel. The receiver gain is 11 dB per Skyworks data sheets. Fanstel measures the increase in Bluetooth range in the Arizona desert without and with SKY66112.
