Migrating the BLE System On Chip (SoC) from Nordic to SiLabs

Client Overview

US-based leading semiconductor company offering innovative solutions for the digital transformation.

Business Need

  • The client wanted to enhance its existing occupancy sensing solution by adding the support of a SiLabs BLE SoC for BLE connectivity to meet the demand of one of its precious customers

VOLANSYS Contribution

  • Developed a Network Co-Processor (NCP) application on the SiLabs EFR32 SoC that supports all the custom characteristics supported by the application firmware
  • Ported BGLIB interface on the ARM Cortex-M4F MCU (ADuCM4050)
  • Enhanced the current MCU application to communicate with the SiLabs BGLIB APIs instead of the Nordic serialization library
  • Tuning the communication channel parameters and application enhancement to have robust communication
  • Added support of a BLE secure connection to ensure customer data protection
  • End to end system validation and testing
