Every BL652 Series module is designed to enable OEMs to add single-mode Bluetooth Low Energy (BLE) v5.0 to
small, portable, power-conscious
devices. The BL652 modules are supported with Laird’s
smartBASIC,
an event-
driven programming language that enables OEMs to make their BLE product development quicker and simpler,
significantly reducing time to market.
smartBASIC
enables customers to develop a complete embedded application
inside the compact BL652 hardware, connecting to a wide array of external sensors via its I2C, SPI, UART, ADC or
GPIO interfaces. The BL652 also
provides flexibility in the OEM’s application development choice with full support
for using Nordic’s SDK and firmware tools.
Based on the world-leading Nordic Semiconductor nRF52832 chipset, the BL652 modules provide ultra-low power
consumption with outstanding wireless range via 4 dBm of transmit power. A broad range of BLE profiles including
Temperature and Heart Rate are available, and
smartBASIC
provides the ideal mechanism to support any BLE
profile development of your choice. This document should be read in conjunction with the
smartBASIC
user
manual.
Note:
BL652 hardware is functionally capable as the nRF52832 chipset used in the module design.
Not all features are currently exposed within Laird’s
smartBASIC
firmware implementation.
