The BL652 modules are supported with Laird’s smartBASIC, an eventdriven 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.
