Rising technology based on TI CC2640 BLE Bluetooth module
The Bluetooth 4.1 module series introduced by Shengrun Technology adopts TI's CC2640 as the core processor-free driving method. Customers only need to connect the module to the application product, and can connect with the mobile phone equipment, digital product equipment and PDA equipment to realize the data. Interaction, completely replacing short-distance wires and cables for intelligent control and management.
Based on TI CC2640 SDK Development Kit
The TTC CC2640 SDK is a rapid development tool developed by Richtech for TI's CC2640 chip development. The purpose is to let developers no longer need to spend a lot of energy on Bluetooth debugging, just focus on the application development of CC2640 chip functions.
The TTC CC2640 SDK provides APIs for Bluetooth parameter settings, Bluetooth data transceiving, and Bluetooth status processing, as well as test programs. Developers no longer need to design test programs. The TTC CC2640 SDK can be used to adapt the TTC-BLE software provided by our company, to facilitate the debugging of data transmission and reception, and to support the data encryption and decryption function, which can greatly shorten the product development cycle.
