Case Study: OTA Enabled Power Optimized Firmware Development of Bluetooth 5.1 Neckband(TWS)
A leading manufacturer of consumer electronic products, approached us to develop a Bluetooth 5.1 Neckband(TWS) device. We carried out the complete firmware development for both the charging case and the earbuds (excluding DSP programming), the implementation of Over The Air (OTA) firmware upgrade capability, and the crucial task of power optimization to ensure a battery life of at least 4 hours for the earbuds and 12 hours for the charging case.
Key Highlights
Firmware for the earbuds & the charging case
Low-power sleep modes, optimized data transmission
Secure OTA firmware updates implementation
Integration with Multiple Devices
Voice Assistance(Google/Alexa) Enabled
