Case Studies

DropMix by Hasbro and Harmonix, developed by NFS
  • Near Field Solutions Ltd (NFS) is a leader in Near Field Communication (NFC), Bluetooth Smart (also known as Bluetooth Low Energy, or BLE), IoT, antenna modeling, and printed electronics.
  • Using our CSR1011 chip and the H13137V3 development kit, NFS created the DropMix Music Gaming System, modifying the chip’s firmware to support the Bluetooth Smart and NFC communications demands.
  • Results: NFS went from initial specifications to first prototypes in just 6 weeks. The project was commercial-ready in less than 9 months.
