Bluetooth Low Energy System On Chip

The package supports the BlueNRG-1 and S2-LP kit platforms available on related web pages to build dual radio applications. It provides a set of BLE demonstration applications with Bluetooth low energy scenarios coupled with the long range capabilities of sub-1GHz technology.

The STSW-BNRG-S2LP-DK SW package contains demonstration applications with complete header and source file sets. A complete set of drivers for interfacing the device peripherals (ADC, GPIOs, I2C, RTC, SPI, Timers, UART, WDG, RTC) and the S2-LP is also provided.

The BLE-Sub1GHz Navigator PC application provides an interactive and user friendly interface to access the BLE-Sub1GHz DK SW package. The main function of the BLE-Sub1GHz Navigator is to select and run the demonstration application in a user friendly manner, without requiring any extra hardware.

Key Features

  • BLE-Sub1GHz Dual Radio Navigator PC application
