39 Bluetooth Smart Q&A Question Can CC2640 use coin cell batteries and how long would the battery operate? Is dual mode Bluetooth needed? Is it possible to upgrade the firmware Over The Air? Can I add BLE to my existing product? Do I have to pay any royalties to Apple? How long should I plan for- from start of development to final, certified, solution? Answer Yes, it can use coin cell. Depending on application, you can get many years of lifetime. If you want to communicate with all devices on the market, older than 2012/2013, they might not be BT Smart Ready and you will need dual-mode. Yes, we have several solutions to do so, including direct update from a Smartphone/Tablet. All our Bluetooth Smart solutions support what is called network processor modes, and can run with any external MCU available on the market. No, BLE is the only solution for accessories to avoid MFI cost. An exception is Apple s own HomeKit. Depending on your knowledge and complexity of the product. Our customers have their final product into production in 6-12 months time.

40 Initial design considerations Question What data rate will your application require? What volume do you expect on a yearly basis? Does your application need to connect to a PC? Would you need a officially adopted profile, or would you make you own? What is the latency requirement? Why is it important? Our BLE stack supports >16KB per second. Note that the throughput is dependent on the smartphone / tablet too. For low volumes (10-100kU) we would recommend using a module. This would save you cost and time for design and certification. For high volumes we recommend development based on TI reference designs. If yes, our CC2540 has USB support for direct connection to PC. We support most officially adopted profiles in addition to proprietary profiles. TI also provides a broad set software starting points covering multiple applications. Bluetooth Smart gives you down to 7.5 ms latency. Is Security important? All our products has hardware accelerated AES 128 encryption module.
