TTC CC2640R2 SDK is a rapid development tool provided by our company for TI's CC2640R2F chip development. Designed to make developers no longer need to focus on Bluetooth debugging, just focus on the application development of CC2640R2 chip functions.


The TTC CC2640R2 SDK provides APIs for Bluetooth parameter setting, Bluetooth data transmission and reception, and Bluetooth status processing. It also provides test programs, and developers do not need to design test programs. Using the TTC CC2640R2 SDK can be adapted to the TTC-BLE software provided by our company, which is convenient for debugging data transmission and reception, and supports data encryption and decryption functions, which can greatly shorten the development cycle of the CC2640R2F.


In order to have richer functions and a better experience as soon as possible, we recommend that you contact the relevant business personnel or consult 400-8050-562 as soon as possible to upgrade the SDK. At the same time, thanks to our customers and developers for their unremitting support for Sunrun, Sunrun will continue to optimize its products and provide better solutions for everyone!
