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
Outcomes
- The customer was able to offer an optimum solution to their valuable customers to win a high-volume long term contract for occupancy sensing solution chipset
