    Challenges

    Insufficient features to meet the end-customer requirement

    Lack of support for SiLabs BLE SoC to enhance the chipset

    Solution

    • 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
